  • Android ViewFlipper is out of control

    - by Doug Miller
    I have an app that uses a ViewFlipper to display some text and images. I have the flipper's flipinterval set to 10 seconds, but also want to allow the user to click a button that will advance the flipper. The code blow works great on 2.2, the view is changed every 10 seconds and if I click flip_button the view is changed and the auto flip steps back in 10 seconds later. The 1.5 and 1.6 versions will remember the manual advance and it will happen every time in the rotation. What am I missing? private void initFlipButton(){ final ImageView flip_button = (ImageView) findViewById(R.id.flip_button); info_button.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { flipper.stopFlipping(); flipper.showNext(); flipper.startFlipping(); } }); } private void initFlipper(){ flipper = (ViewFlipper) findViewById(R.id.flip_dog); flipper.setFlipInterval(10000); flipper.setInAnimation(inFromRightAnimation()); flipper.setOutAnimation(outToLeftAnimation()); flipper.startFlipping(); }

  • Android Content Provider database leak issue

    - by MattC
    I am writing a content provider for this application and in my content provider I am opening a database connection, running a query and returning the cursor of results to the calling program. If I close this database connection in the provider, the cursor has no results. If I leave it open, I get "leak found" errors in my DDMS log. What am I missing here? What's the clean, proper way to return a cursor of database results?

  • Weird Overlay draw behaviour when zooming in the MapView [android]

    - by Itsik
    I've extended Overlay and implemented draw() in order to draw some stuff onto the map. When zooming is done through mapController.zoomIn() (called when doubleTapping the map), the overlay is drawn properly onto the map. BUT whenever I zoom in/out with the built in zoom controller, the overlay is not drawn properly and panning the map is needed to get the overlay refreshed.

  • Android, NetworkInfo.getTypeName(), NullpointerException

    - by moppel
    I have an activity which shows some List entries. When I click on a list item my app checks which connection type is available ("WIF" or "MOBILE"), through NetworkInfo.getTypeName(). As soon as I call this method I get a NullpointerException. Why? I tested this on the emulator, cause my phone is currently not available (it's broken...). I assume this is the problem? This is the only explanation that I have, if that's not the case I have no idea why this would be null. Here's some code snippet: public class VideoList extends ListActivity{ ... public void onCreate(Bundle bundle){ final ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); ... listview.setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> parent, View view, int position, long id) { ... NetworkInfo ni = cm.getActiveNetworkInfo(); String connex = ni.getTypeName(); //Nullpointer exception here if(connex.equals("WIFI")doSomething(); } }); } }

  • Android: Access child views from a ListView

    - by lacker
    I need to find out the pixel position of one element in a list that's been displayed using a ListView. It seems like I should get one of the TextViews and then use getTop, but I can't figure out how to get a child view of a ListView. Thanks! Update: The children of the ViewGroup do not correspond 1-to-1 with the items in the list, for a ListView. Instead, the ViewGroup's children correspond to only those views that are visible right now. So getChildAt operates on an index that's internal to the ViewGroup and doesn't necessarily have anything to do with the position in the list that the ListView uses. :-/

  • Android - Loop Through strings.xml file

    - by Alexis Cartier
    I was wondering if there is anyway to loop through the strings.xml file. Let's say that I have the following format: <!-- FIRST SECTION --> <string name="change_password">Change Password</string> <string name="change_server">Change URL</string> <string name="default_password">password</string> <string name="default_server">http://xxx:8080</string> <string name="default_username">testPhoneAccount</string> <!-- SECOND SECTION --> <string name="debug_settings_category">Debug Settings</string> <string name="reload_data_every_startup_pref">reload_data_every_startup</string> <string name="reload_data_on_first_startup_pref">reload_data_on_first_startup</string> Now let's say I have this: private HashMap<String,Integer> hashmapStringValues = new HashMap<String, Integer>(); Is there a way to iterate only in the second section of my xml file? Maybe wrap the section with a tag like <section2> and then iterate through it? public void initHashMap(){ for (int i=0;i< ???? ;i++) //Here I need to loop only in the second section of my xml file { String nameOfTag = ? // Here I get the name of the tag int value = R.string.nameOfTag // Here I get the associated value of the tag this.hashmapStringValues.put(nameOfTag,value); } }

  • Android - Read PNG image without alpha and decode as ARGB_8888

    - by loki666
    I try to read an image from sdcard (in emulator) and then create a Bitmap image with the BitmapFactory.decodeByteArray method. I set the options: options.inPrefferedConfig = Bitmap.Config.ARGB_8888 options.inDither = false Then I extract the pixels into a ByteBuffer. ByteBuffer buffer = ByteBuffer.allocateDirect(width*height*4) bitmap.copyPixelsToBuffer(buffer) I use this ByteBuffer then in the JNI to convert it into RGB format and want to calculate on it. But always I get false data - I test without modifying the ByteBuffer. Only thing I do is to put it into the native method into JNI. Then cast it into a unsigned char* and convert it back into a ByteBuffer before returning it back to Java. unsigned char* buffer = (unsinged char*)(env->GetDirectBufferAddress(byteBuffer)) jobject returnByteBuffer = env->NewDirectByteBuffer(buffer, length) Before displaying the image I get data back with bitmap.copyPixelsFromBuffer( buffer ) But then it has wrong data in it. My Question is if this is because the image is internally converted into RGB 565 or what is wrong here? ..... Have an answer for it: - yes, it is converted internally to RGB565. Does anybody know how to create such an bitmap image from PNG with ARGB8888 pixel format? If anybody has an idea, it would be great!

  • Web image loaded by thread in android

    - by Bostjan
    I have an extended BaseAdapter in a ListActivity: private static class RequestAdapter extends BaseAdapter { and some handlers and runnables defined in it // Need handler for callbacks to the UI thread final Handler mHandler = new Handler(); // Create runnable for posting final Runnable mUpdateResults = new Runnable() { public void run() { loadAvatar(); } }; protected static void loadAvatar() { // TODO Auto-generated method stub //ava.setImageBitmap(getImageBitmap("URL"+pic)); buddyIcon.setImageBitmap(avatar); } In the getView function of the Adapter, I'm getting the view like this: if (convertView == null) { convertView = mInflater.inflate(R.layout.messageitem, null); // Creates a ViewHolder and store references to the two children views // we want to bind data to. holder = new ViewHolder(); holder.username = (TextView) convertView.findViewById(R.id.username); holder.date = (TextView) convertView.findViewById(R.id.dateValue); holder.time = (TextView) convertView.findViewById(R.id.timeValue); holder.notType = (TextView) convertView.findViewById(R.id.notType); holder.newMsg = (ImageView) convertView.findViewById(R.id.newMsg); holder.realUsername = (TextView) convertView.findViewById(R.id.realUsername); holder.replied = (ImageView) convertView.findViewById(R.id.replied); holder.msgID = (TextView) convertView.findViewById(R.id.msgID_fr); holder.avatar = (ImageView) convertView.findViewById(R.id.buddyIcon); holder.msgPreview = (TextView) convertView.findViewById(R.id.msgPreview); convertView.setTag(holder); } else { // Get the ViewHolder back to get fast access to the TextView // and the ImageView. holder = (ViewHolder) convertView.getTag(); } and the image is getting loaded this way: Thread sepThread = new Thread() { public void run() { String ava; ava = request[8].replace(".", "_micro."); Log.e("ava thread",ava+", username: "+request[0]); avatar = getImageBitmap(URL+ava); buddyIcon = holder.avatar; mHandler.post(mUpdateResults); //holder.avatar.setImageBitmap(getImageBitmap(URL+ava)); } }; sepThread.start(); Now, the problem I'm having is that if there are more items that need to display the same picture, not all of those pictures get displayed. When you scroll up and down the list maybe you end up filling all of them. When I tried the commented out line (holder.avatar.setImageBitmap...) the app sometimes force closes with "only the thread that created the view can request...". But only sometimes. Any idea how I can fix this? Either option.

  • Android: Deciding between SurfaceView and OpenGL (GLSurfaceView)

    - by Rich
    Is there a way to decide up front based on the expected complexity of a game/app in the planning phase whether to use regular Canvas drawing in a SurfaceView or to go with OpenGL? I've been playing around with a Canvas and only need 2D movement, and on a fairly new phone I'm getting pretty decent performance with a bunch of primitive objects and a few bitmaps running around the screen on a solid background. Is it fair to say that if I'm going to be drawing background images and increasing the number of objects being moved and drawn on top of them that I should go straight to OpenGL?

  • Custom event listener on Android app

    - by Bilthon
    Hi everybody, I need to set up a simple event listener to refresh a listview from once in a while. The problem is I don't know how could I generate an event. I know that for events like key or button pressing I just need to implement the handler. But in this specific case I actually need to generate the event, which will be fired everytime another running thread of my app wakes up and refreshes it's list of news from a rss feed. I've done everything, but got stucked in here. Can I get any suggestion or link with some more info on how to implement this? Thanks Nelson R. Perez

  • Animating translation and scaling of view in Android

    - by hgpc
    I have to animate a view from state A to B with changes to its scale, position and scrolling. I know everything about state A (widthA, heightA, topA, leftA, scrollXA, scrollYA) and state B (widthB, heightB, topB, leftB, scrollXB, scrollYB). So far I wrote the following code: AnimationSet animation = new AnimationSet(true); int toXDelta; // What goes here? int toYDelta; // What goes here? TranslateAnimation translateAnimation = new TranslateAnimation(1, toXDelta, 1, toYDelta); translateAnimation.setDuration(duration); animation.addAnimation(translateAnimation); float scale = (float) widthB / (float) widthA; ScaleAnimation scaleAnimation = new ScaleAnimation(1, scale, 1, scale); scaleAnimation.setDuration(duration); animation.addAnimation(scaleAnimation); animation.setAnimationListener(new AnimationListener() { @Override public void onAnimationEnd(Animation arg0) { view.clearAnimation(); // Change view to state B } @Override public void onAnimationRepeat(Animation arg0) {} @Override public void onAnimationStart(Animation arg0) {} }); view.startAnimation(animation); Is this the right way to do this? If so, how should I calculate the values of toXDelta and toYDelta? I'm having trouble finding the exact formula. Thanks!

  • Popup window size in android

    - by Bostjan
    I'm creating a popup window in a listactivity in the event onListItemClick. LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View pop = inflater.inflate(R.layout.popupcontact, null, false); ImageView atnot = (ImageView)pop.findViewById(R.id.aNot); height = pop.getMeasuredHeight(); width = pop.getMeasuredWidth(); Log.e("pw","height: "+String.valueOf(height)+", width: "+String.valueOf(width)); atnot.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { pw.dismiss(); } }); pw = new PopupWindow(pop, width, height, true); // The code below assumes that the root container has an id called 'main' //pw.showAtLocation(v, Gravity.CENTER, 0, 0); pw.showAsDropDown(v, 10, 5); Now, the height and width variables were supposed to be height and width of the layout used for the popup window (popupcontact). But they return 0. I guess that is because the layout isn't rendered yet. Does anyone have a clue, how can I control the size of the popup window without needing to use absolute pixel numbers?

  • Android: scaling a button with a background image.

    - by jkhouw1
    I'm probably just being daft but my Google searches are not working out well. I have a bunch of buttons i add in code that all have dynamic text. I've set a background image for each of these buttons since the default greybutton doesn't work well for my application. This works perfectly and when the text size (or content) changes, the button automatically grows to accommodate the expanded text. What doesn't work is that I'd like the button to scale proportionally - i.e. if the background image is round, i'd like it to stay round rather than oval as the button gets bigger. With an imagebutton, there is a property "Adjust view bounds" that does exactly this but I cant put text on an imagebutton. Is there something equivalent for a regular button? or am I going about this wrong? i also tried setting the width of the button in code, but I can't seem to determine the new height (button.getHeight() returns 0)

  • How to use startMethodTracing APIs on Android?

    - by Rajorshi
    I have recently started working on an app which has both Java and native components. I am trying to generate trace information for both components using Debug.startMethodTracing("myapp") and Debug.startNativeTracing() alternately. However, both are behaving unexpectedly. When I use Debug.startMethodTracing("myapp"), I can see a file /sdcard/myapp.trace being created but it is always empty no matter how long I run my app. When I use Debug.startNativeTracing() and start the emulator with the -trace <tracename> switch, I see a message saying "Trace started", but when I try to run my app, the emulator crashes. Am I missing something obvious here? How do I debug this problem?
