  • unable to set href inside click event of Jquery

    - by akshatrautela
    Hi I am trying to set href using Jquery inside click event of RadioButtonList but that doesnt work If I take the same code to document.ready event it works fine but not in click event. Please advice. $(document).ready(function() { url = "Results.aspx?latitude=" +latitude + "&Longitude=" + longitude; $("a[href='http://www.google.com/']").attr("href", url); // this works.. } $('.rbl input').click(function() { id = $(this).parent().children("input").val(); url = "Results.aspx?latitude=" + latitude + "&Longitude=" + longitude + "&ServiceCenterProductTypeId=" + id; //alert(url); $("a[href='http://www.google.com/']").attr("href", url); //this doesnt work.... }); });

  • Easily use google maps, openstreet maps etc offline.

    - by samkea
    I did it and i am going to explain step by step. The explanatination may appear long but its simple if you follow. Note: All the softwares i have used are the latest and i have packaged them and provided them in the link below. I use Nokia N96 1) RootSign smartComGPS and install it on your phone(i havent provided the signer so that u wuld do some little work. i used Secman' rootsign). 2) Install Universal Maps Downloader, SmartCom OGF2 converter and OziExplorer 3.95.4s on my PC. a) UMD is used to download map tiles from any map source like googlemaps,opensourcemaps etc... and also combine the tiles into an image file like png,jpg,bmp etc... b) SmartCom OGF2 converter is used to convert the image file into a format usable on your mobile phone. c) OziExplorer will help you to calibrate the usable map file so that it can be used with GPS on your mobile phone without the use of internet. 3) Go to google maps or where u pick your maps and pan to the area of your interest. Zoom the map to at least 15 or 16 zoom level where you can see your area clearly and the streets. 4) copy this script in a notepad file and save it on your desktop: javascript:void(prompt('',gApplication.getMap().ge tCenter())); 5) Open the universal maps downloader. You will notice that you are required to add the: left longitude, right longitude,top latitude, bottom latitude. 6) On your map in google maps, doubleclick on the your prefered to most middle point. you will notice that the map will center in that area. 7) copy the script and paste it in the address bar then press enter. You will notice that a dialog with your (top latitude) and longitude respectively pops up. 8) copy the top latitude ONLY and paste it in the corresponding textbox in the UMD. 9) repeat steps 6-7 for the botton latitude. 10)repeat steps 6-7 for left longitude and right longitude too, but u have to copy the longitudes here. (***BTW record these points in the text file as they may be needed later in calibration) 11) Give the zoom level to the same zoom level that you prefered in google maps. 12) Dont forget to choose a path to save your files and under options set the proxy connection settings in UMD if you are using so. 13) Click on start and bingo! there you have your image tiles and a file with an extension .umd will be saved in the same folder. 14) On the UMD, go to tools, click on MapViewer and choose the .umd file. you will now see your map in one piece....and you will smile! 15) Still go to tools and click on map combiner. A dialog will popup for you to choose the .umd file and to enter the IMAGE file name. u can use another extension for the image file like png, jpg etc...i usually use png. 16) Combine.....bingo! there u go! u have an IMAGE file for your map. *I SUGGEST THAT CREATE A .BMP FILE and A .PNG file* 17) Close UMD and open SmartCom OGF2 converter. 18) Choose your .png image and create an ogf2 file. 19) Connect your phone to your PC in Mass Memory mode and transfer the file to the smartComGPS\Maps folder. 20) Now disconnect your phone and load smartComGPS. it will load the map and propt you to add a calibration point. Go ahead and add one calibration point with dummy coordinates. You will notice that it will add another file with extension .map in the smartComGPS\Maps folder. 21) Connect yiur ohone and copy that file and paste it in your working folder on your PC. Delete that .map file from the phone too because you are going to edit it from your PC and put it back. 22) Now Open the OziExplorer, go to file-->Load and Calibrate Map Image. 23) Choose the .bmp image and bingo! it will load with your map in the same zoom level. 24) Now you are going to calibrate. Use the MapView window and take the small box locater to all the 4 cornners of the map. You will notice that the map in the back ground moves to that area too. 25)On the right side, select the Point1 tab. Now you are in calibration mode. Now move the red box in mapview in the left upper corner to calibrate point1. 26) out of mapview go to the the left upper corner of the background map and choose poit (0,0) and your 1st calibration point. You will notice that these X,Y cordinated will be reflected in the Point1 image cordinates. 27) now go back to the text file where you saved your coordibates and enter the top latitude and the left longitude in the corresponding places. 28) Repeat steps 25-27 for point2,point3,point4 and click on save. Thats it, you have calibrated your image and you are about to finish. 29) Go to save and a dilaog which prompts you to save a .map file will poop up. Do save the map file in your working folder. 30) Right click that .map file and edit the filename in the .map file to remove the pc's directory structure. Eg. Change C\OziExplorer\data\Kampala.bmp to Kampala.ogf2. 31) Save the .map file in the smartComGPS\Maps folder on your phone. 32) now open smartComGPS on your phone and bingo! there is your map with GPS capability and in the same zoom level. 33) In smartComGPS options, choose connect and simulate. By now you should be smiling. Whoa! Hope i was of help. i case you get a problem, please inform me Below is the link to the software. regards. http://rapidshare.com/files/230296037/Utilities_Used.rar.html Ok, the Rapidshare files i posted are gone, so you will have to download as described in the solution. If you need more help, go here: http://www.dotsis.com/mobile_phone/sitemap/t-160491.html Some months later, someone else gave almost the same kind of solution here. http://www.dotsis.com/mobile_phone/sitemap/t-180123.html Note: the solutions were mean't to help view maps on Symbian phones, but i think now they ca even do for Windows Phones, iphones and others so read, extract what you want and use it. Hope it helps. Sam Kea

  • JavaFX, Google Maps, and NetBeans Platform

    - by Geertjan
    Thanks to a great new article by Rob Terpilowski, and other work and research he describes in that article, it's now trivial to introduce a map component to a NetBeans Platform application. Making use of the GMapsFX library, as described in Rob's article, which provides a JavaFX API for Google Maps, you can very quickly knock this application together. Click to enlarge the image. Here's all the code (from Rob's article): @TopComponent.Description( preferredID = "MapTopComponent", persistenceType = TopComponent.PERSISTENCE_ALWAYS ) @TopComponent.Registration(mode = "editor", openAtStartup = true) @ActionID(category = "Window", id = "org.map.MapTopComponent") @ActionReference(path = "Menu/Window" /*, position = 333 */) @TopComponent.OpenActionRegistration( displayName = "#CTL_MapWindowAction", preferredID = "MapTopComponent" ) @NbBundle.Messages({ "CTL_MapWindowAction=Map", "CTL_MapTopComponent=Map Window", "HINT_MapTopComponent=This is a Map window" }) public class MapWindow extends TopComponent implements MapComponentInitializedListener { protected GoogleMapView mapComponent; protected GoogleMap map; private static final double latitude = 52.3667; private static final double longitude = 4.9000; public MapWindow() { setName(Bundle.CTL_MapTopComponent()); setToolTipText(Bundle.HINT_MapTopComponent()); setLayout(new BorderLayout()); JFXPanel panel = new JFXPanel(); Platform.setImplicitExit(false); Platform.runLater(() -> { mapComponent = new GoogleMapView(); mapComponent.addMapInializedListener(this); BorderPane root = new BorderPane(mapComponent); Scene scene = new Scene(root); panel.setScene(scene); }); add(panel, BorderLayout.CENTER); } @Override public void mapInitialized() { //Once the map has been loaded by the Webview, initialize the map details. LatLong center = new LatLong(latitude, longitude); MapOptions options = new MapOptions(); options.center(center) .mapMarker(true) .zoom(9) .overviewMapControl(false) .panControl(false) .rotateControl(false) .scaleControl(false) .streetViewControl(false) .zoomControl(false) .mapType(MapTypeIdEnum.ROADMAP); map = mapComponent.createMap(options); //Add a couple of markers to the map. MarkerOptions markerOptions = new MarkerOptions(); LatLong markerLatLong = new LatLong(latitude, longitude); markerOptions.position(markerLatLong) .title("My new Marker") .animation(Animation.DROP) .visible(true); Marker myMarker = new Marker(markerOptions); MarkerOptions markerOptions2 = new MarkerOptions(); LatLong markerLatLong2 = new LatLong(latitude, longitude); markerOptions2.position(markerLatLong2) .title("My new Marker") .visible(true); Marker myMarker2 = new Marker(markerOptions2); map.addMarker(myMarker); map.addMarker(myMarker2); //Add an info window to the Map. InfoWindowOptions infoOptions = new InfoWindowOptions(); infoOptions.content("<h2>Center of the Universe</h2>") .position(center); InfoWindow window = new InfoWindow(infoOptions); window.open(map, myMarker); } } Awesome work Rob, will be useful for many developers out there.

  • Is there a Math.atan2 substitute for j2ME? Blackberry development

    - by Kai
    I have a wide variety of locations stored in my persistent object that contain latitudes and longitudes in double(43.7389, 7.42577) format. I need to be able to grab the user's latitude and longitude and select all items within, say 1 mile. Walking distance. I have done this in PHP so I snagged my PHP code and transferred it to Java, where everything plugged in fine until I figured out J2ME doesn't support atan2(double, double). So, after some searching, I find a small snippet of code that is supposed to be a substitute for atan2. Here is the code: public double atan2(double y, double x) { double coeff_1 = Math.PI / 4d; double coeff_2 = 3d * coeff_1; double abs_y = Math.abs(y)+ 1e-10f; double r, angle; if (x >= 0d) { r = (x - abs_y) / (x + abs_y); angle = coeff_1; } else { r = (x + abs_y) / (abs_y - x); angle = coeff_2; } angle += (0.1963f * r * r - 0.9817f) * r; return y < 0.0f ? -angle : angle; } I am getting odd results from this. My min and max latitude and longitudes are coming back as incredibly low numbers that can't possibly be right. Like 0.003785746 when I am expecting something closer to the original lat and long values (43.7389, 7.42577). Since I am no master of advanced math, I don't really know what to look for here. Perhaps someone else may have an answer. Here is my complete code: package store_finder; import java.util.Vector; import javax.microedition.location.Criteria; import javax.microedition.location.Location; import javax.microedition.location.LocationException;

  • Inconsistent results in R with RNetCDF - why?

    - by sarcozona
    I am having trouble extracting data from NetCDF data files using RNetCDF. The data files each have 3 dimensions (longitude, latitude, and a date) and 3 variables (latitude, longitude, and a climate variable). There are four datasets, each with a different climate variable. Here is some of the output from print.nc(p8m.tmax) for clarity. The other datasets are identical except for the specific climate variable. dimensions: month = UNLIMITED ; // (1368 currently) lat = 3105 ; lon = 7025 ; variables: float lat(lat) ; lat:long_name = "latitude" ; lat:standard_name = "latitude" ; lat:units = "degrees_north" ; float lon(lon) ; lon:long_name = "longitude" ; lon:standard_name = "longitude" ; lon:units = "degrees_east" ; short tmax(lon, lat, month) ; tmax:missing_value = -9999 ; tmax:_FillValue = -9999 ; tmax:units = "degree_celsius" ; tmax:scale_factor = 0.01 ; tmax:valid_min = -5000 ; tmax:valid_max = 6000 ; I am getting behavior I don't understand when I use the var.get.nc function from the RNetCDF package. For example, when I attempt to extract 82 values beginning at stval from the maximum temperature data (p8m.tmax <- open.nc(tmaxdataset.nc)) with > var.get.nc(p8m.tmax,'tmax', start=c(lon_val, lat_val, stval),count=c(1,1,82)) (where lon_val and lat_val specify the location in the dataset of the coordinates I'm interested in and stval is stval is set to which(time_vec==200201), which in this case equaled 1285.) I get Error: Invalid argument But after successfully extracting 80 and 81 values > var.get.nc(p8m.tmax,'tmax', start=c(lon_val, lat_val, stval),count=c(1,1,80)) > var.get.nc(p8m.tmax,'tmax', start=c(lon_val, lat_val, stval),count=c(1,1,81)) the command with 82 works: > var.get.nc(p8m.tmax,'tmax', start=c(lon_val, lat_val, stval),count=c(1,1,82)) [1] 444 866 1063 ... [output snipped] The same problem occurs in the identically structured tmin file, but at 36 instead of 82: > var.get.nc(p8m.tmin,'tmin', start=c(lon_val, lat_val, stval),count=c(1,1,36)) produces Error: Invalid argument But after repeating with counts of 30, 31, etc > var.get.nc(p8m.tmin,'tmin', start=c(lon_val, lat_val, stval), count=c(1,1,36)) works. These examples make it seem like the function is failing at the last count, but that actually isn't the case. In the first example, var.get.nc gave Error: Invalid argument after I asked for 84 values. I then narrowed the failure down to the 82nd count by varying the starting point in the dataset and asking for only 1 value at a time. The particular number the problem occurs at also varies. I can close and reopen the dataset and have the problem occur at a different location. In the particular examples above, lon_val and lat_val are 1595 and 1751, respectively, identifying the location in the dataset along the lat and lon dimensions for the latitude and longitude I'm interested in. The 1595th latitude and 1751th longitude are not the problem, however. The problem occurs with all other latitude and longitudes I've tried. Varying the starting location in the dataset along the climate variable dimension (stval) and/or specifying it different (as a number in the command instead of the object stval) also does not fix the problem. This problem doesn't always occur. I can run identical code three times in a row (clearing all objects in between runs) and get a different outcome each time. The first run may choke on the 7th entry I'm trying to get, the second might work fine, and the third run might choke on the 83rd entry. I'm absolutely baffled by such inconsistent behavior. The open.nc function has also started to fail with the same Error: Invalid argument. Like the var.get.nc problems, it also occurs inconsistently. Does anyone know what causes the initial failure to extract the variable? And how I might prevent it? Could have to do with the size of the data files (~60GB each) and/or the fact that I'm accessing them through networked drives?

  • Building a Store Locator ASP.NET Application Using Google Maps API (Part 1)

    Over the past couple of months I've been working on a couple of projects that have used the free Google Maps API to add interactive maps and geocoding capabilities to ASP.NET websites. In a nutshell, the Google Maps API allow you to display maps on your website, to add markers onto the map, and to compute the latitude and longitude of an address, among many other tasks. With some Google Maps API experience under my belt, I decided it would be fun to implement a store locator feature and share it here on 4Guys. A store locator lets a visitor enter an address or postal code and then shows the nearby stores. Typically, store locators display the nearby stores on both a map and in a grid, along with the distance between the entered address and each store within the area. To see a store locator in action, check out the Wells Fargo store locator. This article is the first in a multi-part series that walks through how to add a store locator feature to your ASP.NET application. In this inaugural article, we'll build the database table to hold the store information. Next, we'll explore how to use the Google Maps API's geocoding feature to allow for flexible address entry and how to translate an address into latitude and longitude pairs. Armed with the latitude and longitude coordinates, we'll see how to retrieve nearby locations as well as how to compute the distance between the address entered by the visitor and the each nearby store.

  • Hibernate many-to-many mapping not saved in pivot table

    - by vincent
    I having problems saving many to many relationships to a pivot table. The way the pojos are created is unfortunately a pretty long process which spans over a couple of different threads which work on the (to this point un-saved) object until it is finally persisted. I associate the related objects to one another right after they are created and when debugging I can see the List of related object populated with their respective objects. So basically all is fine to this point. When I persist the object everything get saved except the relations in the pivot table. mapping files: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.thebeansgroup.jwinston.plugin.orm.hibernate.object"> <class name="ShowObject" table="show_object"> <id name="id"> <generator class="native" /> </id> <property name="name" /> <set cascade="all" inverse="true" name="venues" table="venue_show"> <key column="show_id"/> <many-to-many class="VenueObject"/> </set> </class> </hibernate-mapping> and the other <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.thebeansgroup.jwinston.plugin.orm.hibernate.object"> <class name="VenueObject" table="venue_object"> <id name="id"> <generator class="native"/> </id> <property name="name"/> <property name="latitude" type="integer"/> <property name="longitude" type="integer"/> <set cascade="all" inverse="true" name="shows" table="venue_show"> <key column="venue_id"/> <many-to-many class="ShowObject"/> </set> </class> </hibernate-mapping> pojos: public class ShowObject extends OrmObject { private Long id; private String name; private Set venues; public ShowObject() { } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Set getVenues() { return venues; } public void setVenues(Set venues) { this.venues = venues; } } and the other: public class VenueObject extends OrmObject { private Long id; private String name; private int latitude; private int longitude; private Set shows = new HashSet(); public VenueObject() { } @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } public void setId(Long id) { this.id = id; } public int getLatitude() { return latitude; } public void setLatitude(int latitude) { this.latitude = latitude; } public int getLongitude() { return longitude; } public void setLongitude(int longitude) { this.longitude = longitude; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Set getShows() { return shows; } public void setShows(Set shows) { this.shows = shows; } } Might the problem be related to the lack of annotations?

  • Android SQLlite crashes after trying retrieving data from it

    - by Pavel
    Hey everyone. I'm kinda new to android programming so please bear with me. I'm having some problems with retrieving records from the db. Basically, all I want to do is to store latitudes and longitudes which GPS positioning functions outputs and display them in a list using ListActivity on different tab later on. This is how the code for my DBAdapter helper class looks like: public class DBAdapter { public static final String KEY_ROWID = "_id"; public static final String KEY_LATITUDE = "latitude"; public static final String KEY_LONGITUDE = "longitude"; private static final String TAG = "DBAdapter"; private static final String DATABASE_NAME = "coords"; private static final String DATABASE_TABLE = "coordsStorage"; private static final int DATABASE_VERSION = 1; private static final String DATABASE_CREATE = "create table coordsStorage (_id integer primary key autoincrement, " + "latitude integer not null, longitude integer not null);"; private final Context context; private DatabaseHelper DBHelper; private SQLiteDatabase db; public DBAdapter(Context ctx) { this.context = ctx; DBHelper = new DatabaseHelper(context); } private static class DatabaseHelper extends SQLiteOpenHelper { DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL(DATABASE_CREATE); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { Log.w(TAG, "Upgrading database from version " + oldVersion + " to " + newVersion + ", which will destroy all old data"); db.execSQL("DROP TABLE IF EXISTS titles"); onCreate(db); } } //---opens the database--- public DBAdapter open() throws SQLException { db = DBHelper.getWritableDatabase(); return this; } //---closes the database--- public void close() { DBHelper.close(); } //---insert a title into the database--- public long insertCoords(int latitude, int longitude) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_LATITUDE, latitude); initialValues.put(KEY_LONGITUDE, longitude); return db.insert(DATABASE_TABLE, null, initialValues); } //---deletes a particular title--- public boolean deleteTitle(long rowId) { return db.delete(DATABASE_TABLE, KEY_ROWID + "=" + rowId, null) 0; } //---retrieves all the titles--- public Cursor getAllTitles() { return db.query(DATABASE_TABLE, new String[] { KEY_ROWID, KEY_LATITUDE, KEY_LONGITUDE}, null, null, null, null, null); } //---retrieves a particular title--- public Cursor getTitle(long rowId) throws SQLException { Cursor mCursor = db.query(true, DATABASE_TABLE, new String[] { KEY_ROWID, KEY_LATITUDE, KEY_LONGITUDE}, KEY_ROWID + "=" + rowId, null, null, null, null, null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } //---updates a title--- /*public boolean updateTitle(long rowId, int latitude, int longitude) { ContentValues args = new ContentValues(); args.put(KEY_LATITUDE, latitude); args.put(KEY_LONGITUDE, longitude); return db.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null) 0; }*/ } Now my question is - am I doing something wrong here? If yes could someone please tell me what? And how I should retrieve the records in organised list manner? Help would be greatly appreciated!!

  • JSON Paring - How to show second Level ListView

    - by Sophie
    I am parsing JSON data into ListView, and successfully parsed first level of JSON in MainActivity.java, where i am showing list of Main Locations, like: Inner Locations Outer Locations Now i want whenever i do tap on Inner Locations then in SecondActivity it should show Delhi and NCR in a List, same goes for Outer Locations as well, in this case whenever user do tap need to show USA JSON look like: { "all": [ { "title": "Inner Locations", "maps": [ { "title": "Delhi", "markers": [ { "name": "Connaught Place", "latitude": 28.632777800000000000, "longitude": 77.219722199999980000 }, { "name": "Lajpat Nagar", "latitude": 28.565617900000000000, "longitude": 77.243389100000060000 } ] }, { "title": "NCR", "markers": [ { "name": "Gurgaon", "latitude": 28.440658300000000000, "longitude": 76.987347699999990000 }, { "name": "Noida", "latitude": 28.570000000000000000, "longitude": 77.319999999999940000 } ] } ] }, { "title": "Outer Locations", "maps": [ { "title": "United States", "markers": [ { "name": "Virgin Islands", "latitude": 18.335765000000000000, "longitude": -64.896335000000020000 }, { "name": "Vegas", "latitude": 36.114646000000000000, "longitude": -115.172816000000010000 } ] } ] } ] } Note: But whenever i do tap on any of the ListItem in first activity, not getting any list in SecondActivity, why ?

  • Updating / refreshing a live geojson layer | JSON & JS Variable

    - by Ozaki
    TLDR I am trying to get my geoJSON layer to update, currently it will 1. Create the vector mark, 2. Remove the vector mark, 3. Set the JS variable for lat and lon, 4. Unset the variable??? :S Hey S O. I have a geojson layer set up as follows: //GeoJSON Layer// var layer1 = new OpenLayers.Layer.GML("My GeoJSON Layer", "coordinates", {format: OpenLayers.Format.GeoJSON, styleMap: style_red}); My features are set up as follows: var latitude = 0.0; // as 0.0 it will draw the point in. var longitude = 0.0; // as 0.0 it will draw the point in. //var longitude = getlongitude; where getlongitude = JSON string of longitude. var point = new OpenLayers.Geometry.Point(longitude, latitude); pointFeature = new OpenLayers.Feature.Vector(point, null, style_red); var style_red = OpenLayers.Util.extend({}, layer_style); style_red.strokeColor = "red"; style_red.fillColor = "black"; style_red.fillOpacity = 0.5; style_red.graphicName = "circle"; style_red.pointRadius = 3.8; style_red.strokeWidth = 2; style_red.strokeLinecap = "butt"; and my layer updating function: function UpdateLayer(){ var p = new OpenLayers.Format.GeoJSON({ 'internalProjection': new OpenLayers.Projection("EPSG:900913"), 'externalProjection': new OpenLayers.Projection("EPSG:4326") }); var url = "coordinates"; OpenLayers.loadURL(url, {}, null, function(r) { var f = p.read(r.responseText); map.layers[2].destroyFeatures(); map.layers[2].addFeatures(pointFeature); }); setTimeout("UpdateLayer()",1000) } Any idea what I am doing wrong or what I am missing? Edit1 It now removes the feature (was map.layers[1]) previously... But will not add the new feature.. Edit2 I managed to get it to redraw a point but not with live data. It should draw the point at what (latitude) & (longitude) are equal to. I am trying to set latitude & longitude to some JSON string but every time straight after it sets the variable it changes it back to "undefined" as soon as it passes the line after var latitude? (using firebug & firequery to debug)

  • Progress dialog getting dismissed before the thread gets finished - Android

    - by user264953
    Hi experts, I use the code provided by Fedor in the following link, in order to get the latitude and longitude from my simple demo app. I am trying to fetch the latitude and longitude using the MyLocation class provided by him in that link. What is the simplest and most robust way to get the user's current location in Android? I try to fetch the latitude and longitude on a button click. On the button click, I start an async task and delegate the location fetching work to the do in background method of my asynctask. pre execute - progressdialog initiated. post execute - progress dialog dismissed. This is how, the progress dialog in my code should work and here is the issue which I have. THe progress dialog gets initiated correctly, but even before the latitude and longitude gets printed in the doinbackground method, the progress dialog gets dismissed. I do not understand why this happens. Here is my front end activity public class LocationServices extends Activity { MyLocation myLocation = new MyLocation(); LocationResult locationResult; TextView tv1, tv2; Location location; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); tv1 = (TextView) findViewById(R.id.tv1); tv2 = (TextView) findViewById(R.id.tv2); Button btn = (Button) findViewById(R.id.Button01); btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { new LocationAsyncTasking().execute(); } }); } public class LocationAsyncTasking extends AsyncTask<String, Void, Void> { ProgressDialog dialog; int totalAvail; protected void onPreExecute() { // this.dialog.setMessage("Inserting data..."); dialog = new ProgressDialog(LocationServices.this); this.dialog.setMessage("Fetching data..."); this.dialog.show(); } protected Void doInBackground(String... args) { Looper.prepare(); locationResult = new LocationResult() { public void gotLocation(Location location) { // TODO Auto-generated method stub // LocationServices.this.location = location; System.out.println("Progress dialog should be present now - latitude"+location.getLatitude()); System.out.println("Progress dialog should be present now - longitude"+location.getLongitude()); } }; myLocation.getLocation(LocationServices.this, locationResult); return (null); } protected void onProgressUpdate(Integer... progress) { } protected void onPostExecute(Void unused) { dialog.dismiss(); } } } I am quite puzzled, thinking of what makes this progress dialog disappear even before the SOP in doinbackground is finished. Experts, please help me understand and resolve this issue. Any help in this regard is well appreciated. Looking forward, Best Regards, Rony

  • How can data not stored in a DB be accessed from any activity in Android?

    - by jul
    hi, I'm passing data to a ListView to display some restaurant names. Now when clicking on an item I'd like to start another activity to display more restaurant data. I'm not sure about how to do it. Shall I pass all the restaurant data in a bundle through the intent object? Or shall I just pass the restaurant id and get the data in the other activity? In that case, how can I access my restaurantList from the other activity? In any case, how can I get data from the restaurant I clicked on (the view only contains the name)? Any help, pointers welcome!

  • Introducing the Earthquake Locator – A Bing Maps Silverlight Application, part 1

    - by Bobby Diaz
    Update: Live demo and source code now available!  The recent wave of earthquakes (no pun intended) being reported in the news got me wondering about the frequency and severity of earthquakes around the world. Since I’ve been doing a lot of Silverlight development lately, I decided to scratch my curiosity with a nice little Bing Maps application that will show the location and relative strength of recent seismic activity. Here is a list of technologies this application will utilize, so be sure to have everything downloaded and installed if you plan on following along. Silverlight 3 WCF RIA Services Bing Maps Silverlight Control * Managed Extensibility Framework (optional) MVVM Light Toolkit (optional) log4net (optional) * If you are new to Bing Maps or have not signed up for a Developer Account, you will need to visit www.bingmapsportal.com to request a Bing Maps key for your application. Getting Started We start out by creating a new Silverlight Application called EarthquakeLocator and specify that we want to automatically create the Web Application Project with RIA Services enabled. I cleaned up the web app by removing the Default.aspx and EarthquakeLocatorTestPage.html. Then I renamed the EarthquakeLocatorTestPage.aspx to Default.aspx and set it as my start page. I also set the development server to use a specific port, as shown below. RIA Services Next, I created a Services folder in the EarthquakeLocator.Web project and added a new Domain Service Class called EarthquakeService.cs. This is the RIA Services Domain Service that will provide earthquake data for our client application. I am not using LINQ to SQL or Entity Framework, so I will use the <empty domain service class> option. We will be pulling data from an external Atom feed, but this example could just as easily pull data from a database or another web service. This is an important distinction to point out because each scenario I just mentioned could potentially use a different Domain Service base class (i.e. LinqToSqlDomainService<TDataContext>). Now we can start adding Query methods to our EarthquakeService that pull data from the USGS web site. Here is the complete code for our service class: using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.ServiceModel.Syndication; using System.Web.DomainServices; using System.Web.Ria; using System.Xml; using log4net; using EarthquakeLocator.Web.Model;   namespace EarthquakeLocator.Web.Services {     /// <summary>     /// Provides earthquake data to client applications.     /// </summary>     [EnableClientAccess()]     public class EarthquakeService : DomainService     {         private static readonly ILog log = LogManager.GetLogger(typeof(EarthquakeService));           // USGS Data Feeds: http://earthquake.usgs.gov/earthquakes/catalogs/         private const string FeedForPreviousDay =             "http://earthquake.usgs.gov/earthquakes/catalogs/1day-M2.5.xml";         private const string FeedForPreviousWeek =             "http://earthquake.usgs.gov/earthquakes/catalogs/7day-M2.5.xml";           /// <summary>         /// Gets the earthquake data for the previous week.         /// </summary>         /// <returns>A queryable collection of <see cref="Earthquake"/> objects.</returns>         public IQueryable<Earthquake> GetEarthquakes()         {             var feed = GetFeed(FeedForPreviousWeek);             var list = new List<Earthquake>();               if ( feed != null )             {                 foreach ( var entry in feed.Items )                 {                     var quake = CreateEarthquake(entry);                     if ( quake != null )                     {                         list.Add(quake);                     }                 }             }               return list.AsQueryable();         }           /// <summary>         /// Creates an <see cref="Earthquake"/> object for each entry in the Atom feed.         /// </summary>         /// <param name="entry">The Atom entry.</param>         /// <returns></returns>         private Earthquake CreateEarthquake(SyndicationItem entry)         {             Earthquake quake = null;             string title = entry.Title.Text;             string summary = entry.Summary.Text;             string point = GetElementValue<String>(entry, "point");             string depth = GetElementValue<String>(entry, "elev");             string utcTime = null;             string localTime = null;             string depthDesc = null;             double?

Model I have also created a Model folder and added a new class, Earthquake.cs. The Earthquake object will hold the various properties returned from the Atom feed. Here is a sample of the code for that class. Notice the [Key] attribute on the Id property, which is required by RIA Services to uniquely identify the entity. using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ComponentModel.DataAnnotations;   namespace EarthquakeLocator.Web.Model {     /// <summary>     /// Represents an earthquake occurrence and related information.     /// </summary>     [DataContract]     public class Earthquake     {         /// <summary>         /// Gets or sets the id.         /// </summary>         /// <value>The id.</value>         [Key]         [DataMember]         public string Id { get; set; }           /// <summary>         /// Gets or sets the title.         /// </summary>         /// <value>The title.</value>         [DataMember]         public string Title { get; set; }           /// <summary>         /// Gets or sets the summary.         /// </summary>         /// <value>The summary.</value>         [DataMember]         public string Summary { get; set; }           // additional properties omitted     } }   View Model The recent trend to use the MVVM pattern for WPF and Silverlight provides a great way to separate the data and behavior logic out of the user interface layer of your client applications. I have chosen to use the MVVM Light Toolkit for the Earthquake Locator, but there are other options out there if you prefer another library. That said, I went ahead and created a ViewModel folder in the Silverlight project and added a EarthquakeViewModel class that derives from ViewModelBase. Here is the code: using System; using System.Collections.ObjectModel; using System.ComponentModel.Composition; using System.ComponentModel.Composition.Hosting; using Microsoft.Maps.MapControl; using GalaSoft.MvvmLight; using EarthquakeLocator.Web.Model; using EarthquakeLocator.Web.Services;   namespace EarthquakeLocator.ViewModel {     /// <summary>     /// Provides data for views displaying earthquake information.     /// </summary>     public class EarthquakeViewModel : ViewModelBase     {         [Import]         public EarthquakeContext Context;           /// <summary>         /// Initializes a new instance of the <see cref="EarthquakeViewModel"/> class.         /// </summary>         public EarthquakeViewModel()         {             var catalog = new AssemblyCatalog(GetType().Assembly);

            Initialize();         }           private void Initialize()         {             MapCenter = new Location(20, -170);             ZoomLevel = 2;         }           #region Private Methods           private void OnAutoLoadDataChanged()         {             LoadEarthquakes();

                    }                 }             }, null);         }           #endregion Private Methods           #region Properties           private bool autoLoadData;         /// <summary>         /// Gets or sets a value indicating whether to auto load data.         /// </summary>         /// <value><c>true</c> if auto loading data;

                    RaisePropertyChanged("AutoLoadData");                     OnAutoLoadDataChanged();                 }             }         }           private ObservableCollection<Earthquake> earthquakes;

}             set             {                 if ( mapCenter != value )                 {                     mapCenter = value;                     RaisePropertyChanged("MapCenter");                 }             }         }           private double zoomLevel;         /// <summary>         /// Gets or sets the zoom level.         /// </summary>         /// <value>The zoom level.</value>         public double ZoomLevel         {             get { return zoomLevel;

Another thing to notice is what’s going on in the default constructor. I chose to use the Managed Extensibility Framework (MEF) for my composition needs, but you can use any dependency injection library or none at all. To allow the EarthquakeContext class to be discoverable by MEF, I added the following partial class so that I could supply the appropriate [Export] attribute: using System; using System.ComponentModel.Composition;   namespace EarthquakeLocator.Web.Services {     /// <summary>     /// The client side proxy for the EarthquakeService class.     /// </summary>     [Export]     public partial class EarthquakeContext     {     } }   One last piece I wanted to point out before moving on to the user interface, I added a client side partial class for the Earthquake entity that contains helper properties that we will bind to later: using System;   namespace EarthquakeLocator.Web.Model {     /// <summary>     /// Represents an earthquake occurrence and related information.     /// </summary>     public partial class Earthquake     {         /// <summary>         /// Gets the location based on the current Latitude/Longitude.         /// </summary>         /// <value>The location.</value>         public string Location         {             get { return String.Format("{0},{1}", Latitude, Longitude); }         }           /// <summary>         /// Gets the size based on the Magnitude.         /// </summary>         /// <value>The size.</value>         public double Size         {             get { return (Magnitude * 3); }         }     } }   View Now the fun part! Usually, I would create a Views folder to place all of my View controls in, but I took the easy way out and added the following XAML code to the default MainPage.xaml file. Be sure to add the bing prefix associating the Microsoft.Maps.MapControl namespace after adding the assembly reference to your project. The MVVM Light Toolkit project templates come with a ViewModelLocator class that you can use via a static resource, but I am instantiating the EarthquakeViewModel directly in my user control. I am setting the AutoLoadData property to true as a way to trigger the LoadEarthquakes() method call. The MapItemsControl found within the <bing:Map> control binds its ItemsSource property to the Earthquakes collection of the view model, and since it is an ObservableCollection<T>, we get the automatic two way data binding via the INotifyCollectionChanged interface. <UserControl x:Class="EarthquakeLocator.MainPage"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:bing="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl"     xmlns:vm="clr-namespace:EarthquakeLocator.ViewModel"     mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480" >     <UserControl.Resources>         <DataTemplate x:Key="EarthquakeTemplate">             <Ellipse Fill="Red" Stroke="Black" StrokeThickness="1"                      Width="{Binding Size}" Height="{Binding Size}"                      bing:MapLayer.Position="{Binding Location}"                      bing:MapLayer.PositionOrigin="Center">                 <ToolTipService.ToolTip>                     <StackPanel>                         <TextBlock Text="{Binding Title}" FontSize="14" FontWeight="Bold" />                         <TextBlock Text="{Binding UtcTime}" />                         <TextBlock Text="{Binding LocalTime}" />                         <TextBlock Text="{Binding DepthDesc}" />                     </StackPanel>                 </ToolTipService.ToolTip>             </Ellipse>         </DataTemplate>     </UserControl.Resources>       <UserControl.DataContext>         <vm:EarthquakeViewModel AutoLoadData="True" />     </UserControl.DataContext>       <Grid x:Name="LayoutRoot">           <bing:Map x:Name="map" CredentialsProvider="--Your-Bing-Maps-Key--"                   Center="{Binding MapCenter, Mode=TwoWay}"                   ZoomLevel="{Binding ZoomLevel, Mode=TwoWay}">             <bing:MapItemsControl ItemsSource="{Binding Earthquakes}"                                   ItemTemplate="{StaticResource EarthquakeTemplate}" />         </bing:Map>       </Grid> </UserControl>   The EarthquakeTemplate defines the Ellipse that will represent each earthquake, the Width and Height that are determined by the Magnitude, the Position on the map, and also the tooltip that will appear when we mouse over each data point. Running the application will give us the following result (shown with a tooltip example): That concludes this portion of our show but I plan on implementing additional functionality in later blog posts. Be sure to come back soon to see the next installments in this series.

  • Process: Unable to start service com.google.android.gms.checkin.CheckinService with Intent

    - by AndyRoid
    I'm trying to build a Google map application but keep receiving this in my LogCat. I have all the permissions and meta-data set in my manifest, but am still dumbfounded by this error. Have looked everywhere on SO for this specific error but found nothing relating to com.google.android.gms.checkin A little bit about my structural hierarchy. MainActivity extends ActionBarActivity with three tabs underneath actionbar. Each tab has it's own fragment. On the gMapFragment I create a GPSTrack object from my GPSTrack class which extends Service and implements LocationListener. The problem is that when I start the application I get this message: I have all my libraries imported properly and I even added the google-play-services.jar into my libs folder. I also installed Google Play Services APKs through CMD onto my emulator. Furthermore the LocationManager lm = = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); in my GPSTrack class always returns null. Why is this and how can I fix these issues? Would appreciate an explanation along with solution too, I want to understand what's going on here. ============== Code: gMapFragment.java public class gMapFragment extends SupportMapFragment { private final String TAG = "gMapFragment";

  • Removing and then adding MKAnnotations to a MapView is leaving me with a blank MapView

    - by Chris McCall
    A followup to this quesiton: http://stackoverflow.com/questions/2944581/forcing-reload-of-view-when-returning-from-flipsideview-of-utility-application When returning from the flipside view, I'm calling NSArray *annotations = [NSArray arrayWithArray:[mapView annotations]]; [mapView removeAnnotations:annotations]; To remove all the pins from the map (let me know if this isn't the best way to do this). Then: for(Hole *hole in fetchedObjects) { double latitude = [hole.Latitude doubleValue]; cord.latitude = latitude; double longitude = [hole.Longitude doubleValue]; cord.longitude = longitude; WellPlaceMark *placemark = [[WellPlaceMark alloc] initWithCoordinate:cord withWellType:[NSString stringWithString: hole.WellType]]; [mapView addAnnotation:placemark]; } Plus: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation{ MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentloc"]; if ([annotation isKindOfClass:[MKUserLocation class]]) return nil; if([annotation isKindOfClass:[WellPlaceMark class]]) { ... } annView.animatesDrop=FALSE; return annView; } All of this code seems to be called in the debugger, but when it's finished, I'm presented with a blank map. I've tried zooming out and the pins are nowhere. The map loads up fine on the first try, but once I call removeAnnotations, they never return.

  • Can get coordinates from iPhone simulator, but can't get coordinates from iPhone device

    - by iPhoneARguy
    Hi everyone, I've run into something of a mysterious bug (to me). I have some code to pick out the user's current location on the iPhone SDK. It works fine on the iPhone simulator, but when I try to run it on the actual device, I get a weird error. Here is the code (I am using ASIFormDataRequest to create a POST request): ASIFormDataRequest * request = [ASIFormDataRequest requestWithURL:url]; [request setPostValue:@"testauthor" forKey:@"author"]; [request setPostValue:[[NSNumber numberWithDouble:datum.location.coordinate.latitude] stringValue] forKey:@"latitude"]; NSLog(@"%f", datum.location.coordinate.latitude); NSLog(@"%f", datum.location.coordinate.longitude); [request setPostValue:[[NSNumber numberWithDouble:datum.location.coordinate.longitude] stringValue] forKey:@"longitude"]; [request setPostValue:datum.comment forKey:@"comment"]; On the simulator, NSLog does log both the latitude and longitude, but on the iPhone, it does not. Even stranger, when I go through with the debugger on the device, I try "po datum.location", I get <+###, -###> +/- 223.10m (speed 0.00 mps / course -1.00) @ 2010-05-02 22:18:37 -0400 (### replaced by my location) but when I do "(gdb) po datum.location.coordinate" I get: There is no member named coordinate. Do you guys have any idea why this might happen? Thanks in advance for your help!

  • Geolocation Firefox accurate than iPhone Safari?

    - by johnz
    I just tested Geolocation on Firefox 3.6 and iPhone Safari (os 3.1.3), the result is interesting, firefox is more accurate than safari. any one got idea how to make iPhone Safari result more accurate. this is the code for testing: navigator.geolocation.getCurrentPosition(handler, {enableHighAccuracy: true}); function handler(location) { var message = document.getElementById("message"); message.innerHTML = "<img src='http://maps.google.com/staticmap?sensor=true&center=" + location.coords.latitude + "," + location.coords.longitude + "&size=300x300&maptype=street&zoom=16&key=ABQIAAAAZrVtlT2df2pkfI_RZB_6WBRWTAkRKJS7h1XjKaOTqACHuw1n0BT5cATkkKFnZNGHmrwUw9IilQK0Eg' />"; message.innerHTML+="<p>Longitude: " + location.coords.longitude + "</p>"; message.innerHTML+="<p>Latitude: " + location.coords.latitude + "</p>"; message.innerHTML += "<p>Accuracy: " + location.coords.accuracy + "</p>"; // call the function with my current lat/lon getPlaceFromFlickr(location.coords.latitude, location.coords.longitude, 'output'); } . . test from here

  • Crash on replacing map annotations

    - by Alwin
    Solved it, see below code I'm trying to replace annotations on my MapView depending on the distance between user location and annotation. The annotations are getting replaced like they should, but when I touch te mapview my app crashes. This is de code I have so far: NSMutableArray *tempArray = [[NSMutableArray alloc] init]; for (id object in self.mapAnnotations) { if([object isKindOfClass:[ClosedAnnotation class]]) { ClosedAnnotation *ann = (ClosedAnnotation *)object; CLLocation *tempLocation = [[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance <= 1.0){ [mapView removeAnnotation:object]; OpenAnnotation *openAnnotation = [[OpenAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:openAnnotation]; [tempArray addObject:openAnnotation]; [openAnnotation release]; } else { [tempArray addObject:object]; } } else if([object isKindOfClass:[OpenAnnotation class]]){ OpenAnnotation *ann = (OpenAnnotation *)object; CLLocation *tempLocation = [[[CLLocation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude] autorelease]; double distance = [self.currentLocation getDistanceFrom: tempLocation] / 1000; [tempLocation release]; if(distance > 1.0){ [mapView removeAnnotation:object]; ClosedAnnotation *closedAnnotation = [[ClosedAnnotation alloc] initWithLatitude:ann.coordinate.latitude longitude:ann.coordinate.longitude imageSrc:[ann getImageSrcForAnnotation] title:ann.title tekst:[ann getTextForAnnotation] imageSize:[ann getSizeForImage] username:[ann getUserNameForAnnotation] usertext:[ann getUserTextForAnnotation]]; [mapView addAnnotation:closedAnnotation]; [tempArray addObject:closedAnnotation]; [closedAnnotation release]; } else { [tempArray addObject:object]; } } } [self.mapAnnotations removeAllObjects]; [self.mapAnnotations addObjectsFromArray:tempArray]; [tempArray release]; I solved it by getting rid of the complete "two-class"-structure and handling everything within one annotation class. Works like a charm now.
