  • android : Dynamically changing the content of tab

    - by Jomia
    I want to change the content of a tab? when tha tab is created i set the content of the tab by setContent() method. But if I click again, I want to change the content that means change to another activity. I used setOnTabChangedListener() method, but I am not sure about how to set the content to another intent? Resources res = getResources(); TabHost tabHost=getTabHost(); tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("HOME").setContent(new Intent(getBaseContext(),homeGroup.class))); tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("ABOUT US").setContent(new Intent(getBaseContext(),aboutusGroup.class))); tabHost.setCurrentTab(0); tabHost.setOnTabChangedListener(new OnTabChangeListener() { @Override public void onTabChanged(String tabId) { //here i want to set the content of each tab to another intent // for 'tab1', change to home.class // for 'tab2', change to aboutus.class //how to set these? } }); Please help me.. Thank you..

  • android question about service and the method onstartcommand

    - by user516883
    In a service class there is a method to start the service. If that service gets done executing does it runs onstartcommand from the beginning? Is onstartcommand sorta like a loop as long as the service is running. For example i have onstartcommand { int x = 0; if(x == 0){ } else{ } } After that is complete does it run it again. If you know that answer please explain. I have read google explanation of services and it did not explain that part very well. Is onstartcommand sorta like a loop as long as the service is runnning

  • Android setContentView operation

    - by stormin986
    I've read that it's important to call setContentView() early in an activity since it builds the view objects that may be manipulated by subsequent code in onCreate(). In terms of lifecycle, does the view get drawn to screen as soon as setContentView() is called, or does it allow the onCreate() function to build/populate the information in the view objects, and wait to actually draw it after onCreate() completes? Thanks!

  • Android SurfaceView/Canvas flickering after trying to clear it

    - by Mark D
    So I am trying to clear the Canvas using canvas.drawColor(Color.BLACK) but if I just call this once, the display flickers and displays the old drawing which should have been covered up by the drawColor. Here is the important bits of my code - public void update() { //This method is called by a Thread Canvas canvas = holder.lockCanvas(null); if (canvas != null) { onDraw(canvas); } holder.unlockCanvasAndPost(canvas); } @Override protected void onDraw(Canvas canvas) { if (toClear) { canvas.drawColor(Color.BLACK); //if this is not set to change back to false, it does not flicker toClear = false; } //Draw some objects that are moving around } public void clearScreen() { //This method is called when the user pressed a button toClear = true; } After Googling around a litte, I heard about double buffering but came to the understanding that lockCanvas() and unlockCanvasAndPost() should handle this for me. What is going wrong here?

  • Change Text on Landscape mode with Java Code and not XML (Android)

    - by Chowza
    I wrote my layout entirely in java code because it was just more convenient. (I had a lot of textViews and using for statements were more convenient). However, my TextViews require the day of the week and in portrait mode, I would like to cut the day of the week to a short form. For example, I want "Sunday" to show "Sun" for portrait mode, but "Sunday" for landscape mode. I understand how to do this in XML files, but how do I do it in code? I.e. sample code: LinearLayout parent = new LinearLayout(getApplicationContext()); parent.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT)); TextView example = new TextView; example.setLayoutParams(mparams); example.setText("Sunday"); //<--make this "Sun" when in portrait but "Sunday" in landscape parent.addView(example);

  • ontouch - Switching positions of two views(images) in Android

    - by idish
    I've been looking for that 2 days long and haven't found anything related to it. I'll give an example for my goal. Let's say I have 2 images positioned side by side horizontally. I want the user to be able to switch their positions onlongtouch listener. so let's say that the first image was on the left and the second was on the right side, after switching positions between them, the first image would be in the right and the second would be on the left side. Basically, it is just like in the launcher where you can switch apps positions. Please, if anything is not clear for you, I would like to know, and I'll try to explain it better, thank you.

  • Android Java error handling XML file

    - by Paul
    I'm using SAX and XML reader to read XML weather info from the web and it works fine if the page exists. But if for instance the user inputs an invalid city, zip etc the XML page that gets read from is empty and the app force closes with nullpointerexception. The area that generates the error is here right at open inputstream. Any suggestions?: SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = null; try { sp = spf.newSAXParser(); } catch (ParserConfigurationException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SAXException e) { // TODO Auto-generated catch block e.printStackTrace(); } /* Get the XMLReader of the SAXParser we created. */ XMLReader xr = null; try { xr = sp.getXMLReader(); } catch (SAXException e) { // TODO Auto-generated catch block e.printStackTrace(); } /* Create a new ContentHandler and apply it to the XML-Reader*/ WeatherHandler myExampleHandler = new WeatherHandler(); xr.setContentHandler(myExampleHandler); /* Parse the xml-data from our URL. */ try { xr.parse(new InputSource(url.openStream())); parsedWeatherDataSet = myExampleHandler.getParsedData(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SAXException e) { // TODO Auto-generated catch block e.printStackTrace(); } return parsedWeatherDataSet.toString();

  • Load image blurred Android

    - by Mira
    I'm trying to create a map for a game through an image, where each black pixel is equivalent to a wall, and yellow to flowers(1) and green grass(0) so far i had this image (50x50): http://i.imgur.com/Ydj9Cp2.png the problem here seems to be that, when i read the image on my code, it get's scaled up to 100x100, even tough i have it on the raw folder. I can't let it scale up or down because that will put noise and blur on the image and then the map won't be readable. here i have my code: (...) Bitmap tab=BitmapFactory.decodeResource(resources, com.example.lolitos2.R.raw.mappixel); //tab=Bitmap.createScaledBitmap(tab, 50, 50, false); Log.e("w", tab.getWidth()+"."+tab.getHeight()); for (int i = 0; i < tab.getWidth(); i++) { for (int j = 0; j < tab.getHeight(); j++) { int x = j; int y = i; switch (tab.getPixel(x, y)) { // se o é uma parede case Color.BLACK: getParedes()[x][y] = new Parede(x, y); break; case Color.GREEN: fundo.add(new Passivo(x,y,0)); break; default: fundo.add(new Passivo(x,y,1)); } } } How can i read my image Map without rescaling it?

  • Are there any Android YouTube Player Flags?

    - by stormin986
    My goal is to launch a video in the YouTube player, and then return to my app. I realize I can't control what's going on in another app, BUT I'm wondering if the YouTube app supports any kind of flags or data set in the calling Intent that might support this functionality. Anyone aware of any? I cannot find any documentation on the YouTube app/activities. I had to watch the logs just to figure out which activity to call in the first place (so the choose app dialog didn't appear).

  • Android Timer update UI between multiple tasks

    - by Rilcon42
    I have tried multiple ways to have a single persistent timer update the ui in multiple activities, and nothing seems to work. I have tried an AsyncTask, a Handler, and a CountDownTimer. The code below does not execute the first Log.i statement.... Is there a better way to start the timer (which must be called from another class) in Main (which is the only persistent class)? public static void MainLawTimer() { MainActivity.lawTimer = new CountDownTimer(MainActivity.timeLeft, 1000) { public void onTick(long millisUntilFinished) { Log.i("aaa","Timer running. Time left: "+MainActivity.timeLeft); MainActivity.timeLeft--; if(MainActivity.timeLeft<=0) { //do stuff } else { //call method in another class } }

  • Android: Problem with onMeasure()

    - by droid-test
    Hi I made a custom view. If I add the view to the layout XML file and I set the height to "fill_parent" "specSize" return 0. Why? Code: @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int measuredHeight = 90; int specMode = MeasureSpec.getMode(heightMeasureSpec); int specSize = MeasureSpec.getSize(MeasureSpec.getMode(heightMeasureSpec)); if(specMode != MeasureSpec.UNSPECIFIED){ measuredHeight = specSize; } setMeasuredDimension(60, measuredHeight); } Does anyone know how I can get the height of "fill_parent"? Thanks!
