• Getting really weird long Contact Group names

  - by Pentium10

  When looking at the Contact Groups on Google Contacts or in the People application of my HTC Legend phone, I get the groups names ok eg: Friends, Family, VIP, Favorite etc... But in my application I get really wrong names such as "Family" became "System Group: Family" "Friends" became "System Group: Friends" "Favorite" became "Favorite_5656100000000_3245664334564" I use the below code to read these values: public Cursor getFromSystem() { // Get the base URI for the People table in the Contacts content // provider. Uri contacts = ContactsContract.Groups.CONTENT_URI; // Make the query. ContentResolver cr = ctx.getContentResolver(); // Form an array specifying which columns to return. String[] projection = new String[] { ContactsContract.Groups._ID, ContactsContract.Groups.TITLE, ContactsContract.Groups.NOTES }; Cursor managedCursor = cr.query(contacts, projection, ContactsContract.Groups.DELETED + "=0", null, ContactsContract.Groups.TITLE + " COLLATE LOCALIZED ASC"); return managedCursor; } What I am missing?

• Possible to do rounded corners in custom Progressbar progressDrawable?

  - by b-ryce

  I have a progress bar that is supposed to look like the attached image: And I've made it a long way. I'm very close the only part that isn't working is the rounded corners for the progressDrawable. Here is what mine looks like. (Notice, circled in red, that the fill inside the white outline does not have rounded corners): So, I've found a couple of ways to make this work when the progress bar is colored in with a shape, gradient, or color. BUT, I can't get it with an image as the progressDrawable. Here is my class that extends ProgressBar public class RoundedProgressBar extends ProgressBar{ private Paint paint; public RoundedProgressBar(Context context) { super(context); setup(); } public RoundedProgressBar(Context context, AttributeSet attrs) { super(context, attrs); setup(); } public RoundedProgressBar(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); setup(); ; } protected void setup() { paint = new Paint(); } @Override protected synchronized void onDraw(Canvas canvas) { // First draw the regular progress bar, then custom draw our text super.onDraw(canvas); paint.setColor(Color.WHITE); paint.setStyle(Paint.Style.STROKE); RectF r = new RectF(0,0,getWidth()-1,getHeight()-1); canvas.drawRoundRect(r,getHeight()/2,getHeight()/2, paint); } } Here is my selector: <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@android:id/background" android:drawable="@drawable/slider_track" /> <item android:id="@android:id/secondaryProgress" android:drawable="@drawable/slider_track" /> <item android:id="@android:id/progress" android:drawable="@drawable/slider_track_progress" /> </layer-list> Here are the images used in the selector: slider_track- slider_track_progress- Here is where I embed my progressbar in the layout for my activity <com.android.component.RoundedProgressBar android:id="@+id/player_hp_bar" android:layout_width="fill_parent" android:layout_height="36dip" android:layout_marginLeft="30dip" android:layout_marginRight="30dip" android:max="100" style="?android:attr/progressBarStyleHorizontal" android:progressDrawable="@drawable/slider_layer_list" android:progress="20" android:maxHeight="12dip" android:minHeight="12dip" /> Anyone know how to make this work?

• How do i close the alert dialog that displays custom view

  - by Asdfg

  I have an activity named MainActivity which has a button. On click of that button i am displaying an AlertDialog which contains a custom view named ChildWindow.xml. That custom view has multiple textboxes and a OK button. On click of the OK button, i am calling a method of MainActivity. I am able to access the ChildWindow here as view.getRootView().findViewById(R.id.txtFirstName); Once the user clicks on the OK button, i have to close the alert dialog which i am able to do as view.getRootView().setVisibility(View.GONE); My problem is even though i have closed the the ChildWindow in the above statement, i am able to get reference to the textbox in the next line which means AlertDialog is closed but child window is still there. This is how the OK button click looks like: This works as expected: EditText tb = (EditText) view.getRootView().findViewById(R.id.txtFirstName); Toast toast = Toast.makeText(getApplicationContext(), tb.getText(), Toast.LENGTH_LONG); toast.show(); view.getRootView().setVisibility(View.GONE); This should not work as i am closing the alert dialog and then getting the reference of the textbox but this works too. view.getRootView().setVisibility(View.GONE); EditText tb = (EditText) view.getRootView().findViewById(R.id.txtFirstName); Toast toast = Toast.makeText(getApplicationContext(), tb.getText(), Toast.LENGTH_LONG); toast.show(); I think i am closing the alert dialog but i am not destroying it from the memory. Can someone point me out what am i missing here?

• Enable GPS and network location programmatically on rooted phone?

  - by Steve H

  I'd like to write a simple widget that toggles GPS and network location on and off. I've read that it's not possible to do that normally, but presumably on a rooted phone it must be doable. Does anyone know what the code would be? (I only need the code to toggle the location providers, I know how to make the widget.) It doesn't matter that this isn't a 'good' solution, I don't plan to distribute the widget. If it matters, this would be on an HTC Hero, still running v1.5.

• Recording a screencast of an Android app using the emulator

  - by hgpc

  Unlike the iPhone simulator, the Android emulator doesn't look like an Android device. If you have to create a screencast or promotional video of your Android application, the default skin of the emulator is no good. Is there any way to configure the emulator to look like an Android device? If you have dealt with this already, what other things do you recommend taking into account to record an emulator screencast? Not a programming question per se, but an useful question for Android developers.

• Android - Eclipse setup missing Google APIs

  - by teepusink

  Hi, I just finished setting up my Eclipse with the Android plug-in. (i.e https://dl-ssl.google.com/android/eclipse/) Now when I do the following 1. Eclipse Preferences Android, I see a lot of "Target Name" like Android 1.1 - Android 2.1 However, in the book that I'm reading, I'm also supposed to see a "Target Name" called "Google APIs". I don't see that. What am I missing? Is that a separate install? Thank you, Tee

• Prevent an Activity from being killed by the OS while starting a child activity

  - by Martin Marinov

  I have a main activity which calls a child one via Intent I = new Intent(this, Child.class); startActivityForResult(I, 0); But as soon as Child becomes visible the main activity gets its onStop and immediately after that onDestroy method triggered. And as soon as I call finish() within the Child activity or press the back button, the Child activity closes and the home screen shows (instead of the main activity). How can I prevent the main activity from being destroyed? :\

• Strange behaviour with mediaplayer and seekTo

  - by Mathias Lin

  I'm implementing a custom video player because I need custom video controls. I have an app with only one activity, which on startup shall start playing a video right away. Now, the problem I have is: I don't want the video to start from the beginning, but from a later position. Therefore I do a seekTo(16867). Since seekTo is asynchronous, I place the start call of the mediaplayer (player.start()) in the onSeekComplete of the onSeekCompleteListener. The strange behaviour I experience though is that I can see/hear the video playing from the beginning for a few millisecs before it actually plays from/jumps to the position I seeked to. But - on the other hand - the Log output I call before the player.start returns the correct position 16867, where I seeked to. Below is the relevant code section, the complete class is at http://pastebin.com/jqAAFsuX (I'm on Nexus One / 2.2 StageFright) private void playVideo(String url) { try { btnVideoPause.setEnabled(false); if (player==null) { player=new MediaPlayer(); player.setScreenOnWhilePlaying(true); } else { player.stop(); player.reset(); } url = "/sdcard/myapp/main/videos/main.mp4"; // <--- just for test purposes hardcoded here now player.setDataSource(url); player.setDisplay(holder); player.setAudioStreamType(AudioManager.STREAM_MUSIC); player.setOnCompletionListener(this); player.setOnPreparedListener(this); player.setOnSeekCompleteListener(new MediaPlayer.OnSeekCompleteListener() { public void onSeekComplete(MediaPlayer mediaPlayer) { Log.d("APP", "current pos... "+ player.getCurrentPosition() ); player.start(); // <------------------ start video on seek completed player.setOnSeekCompleteListener(null); } }); player.prepareAsync(); } catch (Throwable t) { Log.e(TAG, "Exception in btnVideoPause prep", t); } } public void onPrepared(MediaPlayer mediaplayer) { width=player.getVideoWidth(); height=player.getVideoHeight(); if (width!=0 && height!=0) { holder.setFixedSize(width, height); progressBar.setProgress(0); progressBar.setMax(player.getDuration()); player.seekTo(16867); // <------------------ seeking to position } btnVideoPause.setEnabled(true); }

• How to partially update views in an app widget without rebuilding all the RemoteViews

  - by Gianni Costanzi

  I'm implementing an app widget and I'd like to be able to change the property of a single view in the widget layout, without rebuilding all the RemoteViews from scratch, which involves loading XML etc and which is not necessary in some circumstances.. Is there a way to say "update property X on view identified by a specific ID in the current widget layout"? I've seen that there is a partiallyUpdateAppWidget method in the AppWidgetManager class but I can't understand nor if it is meant for this purpose neither how it must be used.. Can you help me or point me to a useful link or example?

• Passing ArrayList<String> between tabs

  - by Christophe

  Hi all, I'm not very clear about the Intent object and how to use it to pass data between Activities. In my application I have several tabs between which I want to pass ArrayList. Here is a sample code I plan to use, but I'm missing the part where the main activity catches the Intent and passes it to the new activity on start : 1. myTabs.java == This is where I think I need to add some code to pass the data between TabOne and TabTwo. For now it is just using the sample code of the TabActivity sample. public class myTabs extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Reusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, TabPeopleActivity.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("TabOne").setIndicator("TabOne", res.getDrawable(R.drawable.ic_tab_one)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, TabTransactionActivity.class); spec = tabHost.newTabSpec("TabTwo").setIndicator("TabTwo", res.getDrawable(R.drawable.ic_tab_two)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTab(0); } } 2. TabOne.java == I added a piece of code in the onStop procedure to fill in the Intent data with the array I want to pass to TabTwo. Not sure it is the right way to do though. public class TabOne extends Activity { [...] private ArrayList<String> arrayPeople; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tabone); arrayPeople = new ArrayList<String>(); [... here we modify arrayPeople ...] } /** Called when the activity looses focus **/ @Override public void onStop(){ Intent myIntent = new Intent(); myIntent.putStringArrayListExtra("arrayPeople", arrayPeople); this.setIntent(myIntent); } } 3. TabTwo.java == Here I am trying to fetch the ArrayList from the Intent that is supposed to be passed when the Activity starts. But how to do this? public class TabTwo extends Activity { private ArrayList<String> arrayPeople; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.transaction); Intent myIntent = new Intent(); myIntent = this.getIntent(); arrayPeople = myIntent.getStringArrayListExtra("arrayPeople"); } } Thanks for your ideas !

• Retrieving and displaying a contact name from a contact id while using a SimpleCursorAdapter

  - by Henrique

  I am storing information on the phone's contacts using a sqlite database. The fields I am storing are: _id, contact_id, body where _id is the row's id, contact_id is the phone contact's id and body is just a simple text which is the actual information I am storing. I'm using a SimpleCursorAdapter to map the data to the view, like so: Cursor cursor = database.fetchInformation(); // fetch info from DB String[] from = new String[] { CONTACT_ID, BODY }; int[] to = new int[] { R.id.contact, R.id.body }; SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.row, cursor, from, to); getListView().setAdapter(adapter); What I would actually want is to get the contact name that is associated with this CONTACT_ID, and have that be shown in the view. I can't seem to find a simple solution. I've tried implementing my own SimpleCursorAdapter and rewriting setViewText(TextView, String) but it didn't work. Also, it just seems overly complicated for such a simple task. Any help? Thanks.

• Android HelloGoogleMaps to OSMdroid (Open Street Maps)

  - by birgit

  I am trying to reproduce a working HelloGoogleMaps app in Open Street Maps - but I have trouble including the itemized overlay in OSMdroid. I have looked at several resources but I cannot figure out how to fix the error on OsmItemizedOverlay - I guess I am constructing OsmItemizedOverlay wrongly or have a mixup with OsmItemizedOverlay and ItemizedOverlay? But everything I tried to change just raised more errors... "Implicit super constructor ItemizedOverlay() is undefined. Must explicitly invoke another constructor" "Cannot make a static reference to the non-static method setMarker(Drawable) from the type OverlayItem" - I hope someone can help me getting the class definition straight? Thanks so much! package com.example.osmdroiddemomap; import java.util.ArrayList; import android.app.AlertDialog; import android.content.Context; import android.graphics.Point; import android.graphics.drawable.Drawable; import org.osmdroid.api.IMapView; import org.osmdroid.views.*; import org.osmdroid.views.overlay.*; import org.osmdroid.views.overlay.OverlayItem.HotspotPlace; public class OsmItemizedOverlay extends ItemizedOverlay<OverlayItem> { Context mContext; private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); //ERRORS are raised by the following 3 lines: public OsmItemizedOverlay(Drawable defaultMarker, Context context) { OverlayItem.setMarker(defaultMarker); OverlayItem.setMarkerHotspot(HotspotPlace.CENTER); mContext = context; } public void addOverlay(OverlayItem overlay) { mOverlays.add(overlay); populate(); } @Override protected OverlayItem createItem(int i) { return mOverlays.get(i); } @Override public int size() { return mOverlays.size(); } protected boolean onTap(int index) { OverlayItem item = mOverlays.get(index); AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); dialog.setTitle(item.getTitle()); dialog.setMessage(item.getSnippet()); dialog.show(); return true; } @Override public boolean onSnapToItem(int arg0, int arg1, Point arg2, IMapView arg3) { // TODO Auto-generated method stub return false; } }

• Exception when creating an activity: Could not select item Parcel unable to marshal value

  - by user341652

  Hi, I am trying to call an Activity from another instance of the activity. The code is supposed to be a simple file browser (part of a larger application). I am using a ListActivity, and when an item (such as a folder) is selected, it is supposed to open it up in the new Activity. I have a feeling it is a problem with the AndroidManifest (which just has the basic tag). Any assistance would be appreciated. Thanks, Steve

• AVD properties for Motorola Flipout?

  I'm looking to create AVDs to test my apps on, and i'm trying to figure out the correct settings for a square screen such as the new Motorola Flip Out. I don't see a wikipedia article for it, or many specs... On a related note, what about tablets? Actually.. Why aren't there a set of AVD instances with params from popular devices.. or at least a site that lists them for each of the 60+ devices. Thanks in advance :)

• getting the Contact's Birthday of a HTC Sense phone

  - by Pentium10

  I am not sure, but probably HTC Sense does the following, syncs my Facebook contacts to my phone along with their mobile number and their birthday. This shows well in the agenda and the user panel. But as it turns out it doesn't use the standard SDK way to store the birthdays. As if I use the following code to get the birthday of a contact it returns NO data for those contacts. public String getBirthday() { if (data.containsKey(BIRTHDAY)) { return CRUtils.getString(data, BIRTHDAY); } else { // read birthday Cursor c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + this.getId() + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, null); if (c != null) { try { if (c.moveToFirst()) { String s = c.getString(0); this.setBirthday(s); return s; } } finally { c.close(); } } return ""; } } How can I fix this?

• Show Alertdialog and use vibrator

  - by user1007522

  I'm having a class that implements RecognitionListener like this: public class listener implements RecognitionListener I wanted to show a alertdialog and use the vibrator but this isn't possible because I need to provide a context what I don't have. My alertdialog code was like this: new AlertDialog.Builder(this) .setTitle("dd") .setMessage("aa") .setNeutralButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { } }) .show(); But the AlertDialog.Builder(this) wants a context, the same problem with my vibrator code: v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); The getSystemService method isn't available. My code that starts the class: sr = SpeechRecognizer.createSpeechRecognizer(this); sr.setRecognitionListener(new listener()); Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"voice.recognition.test"); intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,5); sr.startListening(intent); Whats the best way to solve this?

• OnTouch event consumes click event and prevents execution in parent

  - by Taig

  I'm having a FrameLayout that has an extended ImageView (github) as a child. When I set an onClick()-Event to the FrameLayout it won't be triggered. The reason appears to be the onTouch() method's return value. If I set the ACTION_DOWN's return value to false the event is passed along properly - but then the Multitouch functionalities break. Also running performClick() in the ACTION_UP event comes to nothing. How to handle those events correctly?

This is the code of the activity: public class ItemConsultaGastos extends ListActivity { private DataHelper dh ; TextView seleccion; private static String[] FROM = {DataHelper.MES, DataHelper.ANO}; private static int[] TO = {R.id.columnaMes, R.id.columnaAno }; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.muestrafechas); this.dh = new DataHelper(this); Cursor cursor = dh.selectAllMeses(); startManagingCursor(cursor); this.mostrarFechas(cursor); ListView lv = getListView(); lv.setOnItemLongClickListener(new OnItemLongClickListener(){ @Override public boolean onItemLongClick(AdapterView<?> arg0, View arg1,int row, long arg3) { //here is where i got the classCastException. String[] tmp = (String[]) arg0.getItemAtPosition(row); //tmp[0] ist the Text of the first TextView displayed by the clicked ListItem Log.w("Gastos: ", "El texto: " + tmp[0].toString()); return true; } }); } private void mostrarFechas(Cursor cursor) { SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.muestrafechasitem,cursor, FROM, TO); setListAdapter(adapter); } } ///// This is the xml where a define the rows to show on the listview <TextView android:id="@+id/espacio" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text=" " /> <TextView android:id="@+id/columnaAno" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="20sp" android:layout_toRightOf="@+id/espacio"/> <TextView android:id="@+id/separador1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text=" -- " android:layout_toRightOf="@+id/columnaAno" android:textSize="20sp" /> <TextView android:id="@+id/columnaMes" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toRightOf="@+id/separador1" android:textSize="20sp"/>

• getView() in CountDownTimer's onTick return sometimes null

  - by HexWrench

  I had recently a crash report where I could see that in the CountDownTimer's onTick method the getView() call returns null. I use the onTick method to display the remaining time in a textView. The textView is inside a Fragment. Since the CountDownTimer runs in the UI thread I have no idea why this had happened. What could be the cause for this and what is a possible workaround for this problem? Thanks!
