  • Asynchronous Html.ImageGetter for setting multiple images in a TextView

    - by thedude19
    I'm writing an application that takes HTML pages and parses them to display on the screen. Specifically, this application pulls HTML from a message board and lists posts made by users. The problem is that a lot of the content in posts are pictures in <img> tags, so I need to write a Html.ImageGetter to handle the downloading of the images. My textView.setText() method will look like this: myTextView.setText(Html.fromHtml(myText, new ImageGetter() { @Override public Drawable getDrawable(String source) { Drawable d; // Need to async download image here return d; } }, null)); Doing this synchronously is trivial, but is there a suggested way to do this asynchronously so that it doesn't lock up my UI thread? I would also like to eventually build in caching of these images, but I imagine that would be pretty simple once the async downloading was there.

  • Extended SurfaceView's onDraw() method never called

    - by Gab Royer
    Hi, I'm trying to modify the SurfaceView I use for doing a camera preview in order to display an overlaying square. However, the onDraw method of the extended SurfaceView is never called. Here is the source : public class CameraPreviewView extends SurfaceView { protected final Paint rectanglePaint = new Paint(); public CameraPreviewView(Context context, AttributeSet attrs) { super(context, attrs); rectanglePaint.setARGB(255, 200, 0, 0); rectanglePaint.setStyle(Paint.Style.FILL); rectanglePaint.setStrokeWidth(2); } @Override protected void onDraw(Canvas canvas){ canvas.drawRect(new Rect(10,10,200,200), rectanglePaint); Log.w(this.getClass().getName(), "On Draw Called"); } } public class CameraPreview extends Activity implements SurfaceHolder.Callback{ private SurfaceHolder holder; private Camera camera; @Override protected void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); // We remove the status bar, title bar and make the application fullscreen requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // We set the content view to be the layout we made setContentView(R.layout.camera_preview); // We register the activity to handle the callbacks of the SurfaceView CameraPreviewView surfaceView = (CameraPreviewView) findViewById(R.id.camera_surface); holder = surfaceView.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { Camera.Parameters params = camera.getParameters(); params.setPreviewSize(width, height); camera.setParameters(params); try { camera.setPreviewDisplay(holder); } catch (IOException e) { e.printStackTrace(); } camera.startPreview(); } public void surfaceCreated(SurfaceHolder holder) { camera = Camera.open(); } public void surfaceDestroyed(SurfaceHolder holder) { camera.stopPreview(); camera.release(); } }

  • onPause/onResume activity issues

    - by Josh
    I have a small test application I am working on which has a timer that updates a textview to countdown from 100 to 0. That works fine, but now I am trying to pause the application if the user presses the back button on the phone and then restart the timer from where they left off when they reopen the app. Here is the code I am using: @Override public void onPause() { if(this._timer_time_remaining > 0) { this.timer.cancel(); } super.onPause(); Log.v("Pausing", String.format("Pausing with %d", this._timer_time_remaining)); } @Override public void onResume() { super.onResume(); Log.v("Resuming", String.format("Resuming with %d", this._timer_time_remaining)); if(this._timer_time_remaining > 0) { setContentView(R.layout.in_game); start_timer(this._timer_time_remaining); } } The start_timer() method creates a CountDownTimer which updates the textview in the onTick method and updates the this._timer_time_remaining int variable. CountDownTimer and _timer_time_remaining are both declared at the class level like this: private CountDownTimer timer; private int _timer_time_remaining; From the Log.v() prints I see that the _timer_time_remaining variable has the correct number of seconds stored when onPause is called, but it is set back to 0 when onResume starts. Why does the variable get reset? I thought that the application would continue to run in the background with the same values. Am I missing something? This is all declared in a class that extends Activity. Thanks in advance!

  • Inform Activity from a BroadcastReceiver ONLY if it is in the foreground

    - by Zordid
    Hi there! Maybe it's easy, but I couldn't really figure this out right so far... I got a BroadcastReceiver waiting to get triggered by the AlarmMangager - this works fine. Now: because the event, if it occurs, needs to refresh some elements on screen of the main Activity, I would like to send an Intent from that background BroadcastReceiver to my Activity - but only if it is currently in the foreground, aka active. If it is not running or not visible, I don't care - and the last thing I want to do is start the Activity by my intent! I handle repainting of the views in my onResume method, so I don't care at all. Any hints on how to do that? Thanks! EDIT: my BroadcastReceiver is waiting for alarms that must be notified to the user. So, it must be there and declared in the manifest. The problem is: it will have to decide whether the mentioned Activity is currently up in front or not.

  • NullPointerException when Using requestWindowFeature(Window.FEATURE_NO_TITLE) on ListActivity Extending Activity

    - by ColorWP.com
    I have a ListActivity extending class and I am trying to hide the default TitleBar (I think it's called ActionBar) using the code below. It works on a regular activity, but not on the ListActivity. How do I accomplish the same in this scenario? public class MyClass extends ListActivity{ @Override public void onCreate(Bundle b) { requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(b); // Tried Window.FEATURE_NO_TITLE here as well setContentView(R.layout.activity_myclass); getActionBar().setDisplayHomeAsUpEnabled(true); } }

  • Nexus One & Windows XP USB Driver

    - by Stefan
    I've been unable to get my Nexus One working as a development phone on Windows XP. I've got the driver (revision 3 for N1 support), I've got it installed according to the official installation guide, and the phone appears in the Device Manager just as the guide says it should. However, adb still can't find the phone. 'adb devices', for example, returns no active devices. Am I forgetting some basic step? One thing I've noticed is that the driver is labeled in Windows as version 2 released November, 2009 (I need version 3 from January 2010 for N1 support). However, I've never had version 2 installed. I've used the SDK to download version 3 several times - even deleted it and redownloaded it. I've uninstalled/reinstalled the version 3 driver multiple times. It still says version 2. Is this the problem, or this something completely unrelated? Note: The phone is working as a dev phone on Ubuntu, so I know the phone/cable/etc. are good. It's either my fault or the driver's.

  • Linux Mint something wrong with my .bashrc

    - by user2309862
    The path of my .basrc file is /home/vamsi/.bashrc It is weird that my file has nothing but the path I set. I think I am using a file at the wrong location or that I have lost my .bashrc file as none of the environment variables set here seem to work. #ANDROID_DEV ANDROID_HOME=/opt/android-sdk-linux export ANDROID_HOME PATH= $PATH:$ANDROID_SDK_HOME/tools export PATH PATH=$PATH:$ANDROID_HOME/platform-tools export PATH PATH=$PATH:$ANDROID_HOME/build-tools export PATH #MAVEN-PATH M2_HOME=/opt/apache-maven-3.1.0 export M2_HOME M2=$PATH:$M2_HOME/bin export M2 I was prompted to install maven2 in order to use mvn, but the android command cannot be found. Could you please help me find a solution to this issue. EDIT: Meanwhile,I tried this: export PATH=${PATH}:/opt/android-sdk-linux/platform-tools export PATH=${PATH}:/opt/android-sdk-linux/tools Now,the output of $PATH echoes: bash: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/android-sdk-linux/platform-tools:/opt/android-sdk-linux/build-tools: No such file or directory

  • Cant get Jquery ui autocomplete widget to work

    - by Boob
    Im trying to develop my first ASP.NET MVC web app and have run into a problem with the jquery ui autocomplete widget. At the moment I have a form with a number of text boxs which would lend themselves well to an autocomplete ability. The code for my "Make"(Car make) text box is show below: jquery: $(function() { $("#Make").autocomplete({ source: '<%=Url.Action("Make","AutoComplete") %>' }); }); ASP.NET MVC controller: public ActionResult Make(string term) { return Json(Service.GetHints(HintType.Make, term, 20)); } GetHints() returns an IList of Hints, an object with just label and value string properties. The documentation implies that this is what I should be returning to the jquery but it doesnt want to work? Can anyone give me any advice/help?

  • NetworkImageView with InfoWindowAdapter

    I'm having trouble trying to use Volley's NetworkImageView with an InfoWindow of Google Maps API v2. My markers shows an InfoWindow with an image fetched from the internet.

  • XML Table layout? Two EQUAL-width rows filled with equally width buttons??

    - by Oliver Goossens
    Hi heres a part from my XML for LAND format: <TableLayout android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="center" android:stretchColumns="*"> <TableRow> <Button android:id="@+id/countbutton" android:text="@string/plus1"/> <Button android:id="@+id/resetbutton" android:text="@string/reset" /> </TableRow> </TableLayout> And now what I dont get - the WIDTH of one row and also of the button depends on the TEXT inside the button. If the both texts are equaly long lets say : TEXT its ok - the table half is in the middle of the screen. But if they have different size - lets say "A" and "THIS IS THE LONG BUTTON" the CENTER of the table isnt in the middle of the screen anymore and so the buttons are not equally width... Cant find any solution... Please advise... Thank you Oliver Goossens

  • Admob ads will not display when placed inside a tabview

    - by smith324
    I've been trying to get my ads to display in this type of layout. Tabs - LinearLayout - ListView - header. The header is set via addHeaderView and is displaying normally. If I were to move the ads anywhere else they display normally (so its not a setup issue). Using ads in the header of a listview works fine in my other projects. So this seems to be a very specific problem, the ads simply refuse to display when placed in the header of a listview inside a tabhost. My logs show no activity from admob at all. There is either a bug here or limitation of the sdk. Does anyone have any experience or insight into this issue? EDIT I found the solution. It actually had to do with padding that was in the root of my Tabview. For more checkout my answer here

  • Variable cannot be resolved

    - by Devel
    Hi, I am trying to create an item list, diffrent for each i and j variable. My code is: if (i == 0) { if (j == 0) { final CharSequence[] items = {"4:45", "5:00"} } else if (j == 1) { final CharSequence[] items = {"4:43", "4:58"} } else if (j == 2) { final CharSequence[] items = {"4:41", "4:56"} } else { final CharSequence[] items = {"4:38", "4:53"} } ... new AlertDialog.Builder(this) .setTitle("Hours") .setItems(items, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialoginterface, int i) { // getStation(i); } }) .show(); } I get an error in the line .setItems(items,: items cannot be resolved I think that the compiler thinks that the CharSequence[] items may not be initialised or something... How can I make this programme run?

  • Stop All Started Services on App Close / Exit

    Is it possible to stop all started services when the user hits the Home Button? I use: startService(new Intent(ClassName.this, ClassName2.class)); stopService(new Intent(ClassName.this, ClassName2.class)); This means I will have to somehow add the 'stopService()' for 7+ of my app classes I've researched this topic and I think there's 'onTerminate' but still not sure how this should be implemented. Any help or hints would be appreciated! Thanks!

  • QT creator/qt embedded widget demo problem

    I have downloaded the source code for the embedded widget demos from nokia and tried to get it to compile--I end up with the following error: Compiler (mingw32) message : In file included from ../../src/basicgraph/qtbasicgraph.cpp:9: ../../src/basicgraph/qtbasicgraph.h:14:17: QtGui: No such file or directory The offending line is #include <QtGui> QT creator 1.2.0, QT 2009.03 I have checked paths, etc, and all seems fine. I have checked to make sure that I have implicitly included QT += gui and that I have NOT included QT -= gui anywhere in the .pro and .pri files. After making no changes, I used VS2005 and the appropriate commercial version of QT 4.4.3, and it compiled and ran fine I have googled the error, and have found others asking similar questions (but not here) but no posted answers...so I would appreciate any help. thanks Jonathan Howland

    - by dusker
    Hi Everyone, here's a problem that i've run into lately: I have a listview with a custom adapter class, the adapter takes in a listview and populates the listview with elements from it. Now, i'd like to have a button on each row of a listview to remove the item from it. How should i approach this problem? Is there a way to remotely trigger a method in the activity class and call notifydatachanged() method on the adapter to refresh the listview? thanks in advance for your help and some code snippets if possible best regards peter

  • Python TKinter connect variable to entry widget

    - by Sano98
    Hi everyone, I'm trying to associate a variable with a Tkinter entry widget, in a way that: Whenever I change the value (the "content") of the entry, mainly by typing something into it, the variable automatically gets assigned the value of what I've typed. Without me having to push a button "Update value " or something like that first. Whenever the variable gets changed (by some other part of the programm), I want the entry value displayed to be adjusted automatically. I believe that this could work via the textvariable. I read the example on http://effbot.org/tkinterbook/entry.htm, but it is not exactly helping me for what I have in mind. I have a feeling that there is a way of ensuring the first condition with using entry's "validate". Any ideas? Thank you for your input! Sano

  • Action Item shown only in Landscape?

    - by roboguy12
    I was just wondering if it were at all possible for an Action Bar icon to only be shown when the device is in landscape mode? In portrait I have an onscreen button for a certain task, but in order to take advantage of all of the screen-space in landscape, that button won't fit. So I was wondering if I could put it in the Action Bar, but it would only be necessary when the device is in landscape. Thanks!

  • How to set clickable and highlightable a ViewStub?

    - by Pentium10
    I have ViewStubs in my layout. If I set clickable and implement the OnClickListener this does work only on the root of the element. But the layout holds parent elements, and when I click on those the click is not recognized. How do I make a full row/view of ViewStub as whole to be clickable and highlightable like a ListView elements? Also what do I have to add to get that orange highlight?

  • Deleting items from a ListView using a custom BaseAdapter

    - by HXCaine
    I am using a customised BaseAdapter to display items on a ListView. The items are just strings held in an ArrayList. The list items have a delete button on them (big red X), and I'd like to remove the item from the ArrayList, and notify the ListView to update itself. However, every implementation I've tried gets mysterious position numbers given to it, so for example clicking item 2's delete button will delete item 5's. It seems to be almost entirely random. One thing to note is that elements may be repeated, but must be kept in the same order. For example, I can have "Irish" twice, as elements 3 and 7. My code is below: private static class ViewHolder { TextView lang; int position; } public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.language_link_row, null); holder = new ViewHolder(); holder.lang = (TextView)convertView.findViewById(R.id.language_link_text); holder.position = position; final ImageView deleteButton = (ImageView) convertView.findViewById(R.id.language_link_cross_delete); deleteButton.setOnClickListener(this); convertView.setTag(holder); deleteButton.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.lang.setText(mLanguages.get(position)); return convertView; } I later attempt to retrieve the deleted element's position by grabbing the tag, but it's always the wrong position in the list. There is no noticeable pattern to the position given here, it always seems random. // The delete button's listener public void onClick(View v) { ViewHolder deleteHolder = (ViewHolder) v.getTag(); int pos = deleteHolder.position; ... ... ... } I would be quite happy to just delete the item from the ArrayList and have the ListView update itself, but the position I'm getting is incorrect so I can't do that. Please note that I did, at first, have the deleteButton clickListener inside the getView method, and used 'position' to delete the value, but I had the same problem. Any suggestions appreciated, this is really irritating me.
