How to setContentView in a fragment?

Question

Now I've got this fragment which i want to use setContentView with but so far i cant find how. You can see my case in the code below, im not trying to inflate a layout, im trying to use it with the view called SampleView. So how can I do that? Thanks in advance

public class largeImageScroller extends SherlockFragment {  // Physical display width and height. private static int displayWidth = 0; private static int displayHeight = 0;  /** Called when the activity is first created. */ public View onCreateView(LayoutInflater inflater, ViewGroup group, Bundle saved) {          getActivity();         // displayWidth and displayHeight will change depending on screen         // orientation. To get these dynamically, we should hook onSizeChanged().         // This simple example uses only landscape mode, so it's ok to get them         // once on startup and use those values throughout.          Display display = ((WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();         displayWidth = display.getWidth();                      displayHeight = display.getHeight();              // SampleView constructor must be constructed last as it needs the         // displayWidth and displayHeight we just got.         setContentView(new SampleView(this)); }  private static class SampleView extends View {         private static Bitmap bmLargeImage; //bitmap large enough to be scrolled         private static Rect displayRect = null; //rect we display to         private Rect scrollRect = null; //rect we scroll over our bitmap with         private int scrollRectX = 0; //current left location of scroll rect         private int scrollRectY = 0; //current top location of scroll rect         private float scrollByX = 0; //x amount to scroll by         private float scrollByY = 0; //y amount to scroll by         private float startX = 0; //track x from one ACTION_MOVE to the next         private float startY = 0; //track y from one ACTION_MOVE to the next          public SampleView(Context context) {                 super(context);                  // Destination rect for our main canvas draw. It never changes.                 displayRect = new Rect(0, 0, displayWidth, displayHeight);                 // Scroll rect: this will be used to 'scroll around' over the                 // bitmap in memory. Initialize as above.                 scrollRect = new Rect(0, 0, displayWidth, displayHeight);                  // Load a large bitmap into an offscreen area of memory.                 bmLargeImage = BitmapFactory.decodeResource(getResources(),                         R.drawable.ground_floor_b);         }          @Override         public boolean onTouchEvent(MotionEvent event) {                  switch (event.getAction()) {                         case MotionEvent.ACTION_DOWN:                                 // Remember our initial down event location.                                 startX = event.getRawX();                                 startY = event.getRawY();                                 break;                          case MotionEvent.ACTION_MOVE:                                 float x = event.getRawX();                                 float y = event.getRawY();                                 // Calculate move update. This will happen many times                                 // during the course of a single movement gesture.                                 scrollByX = x - startX; //move update x increment                                 scrollByY = y - startY; //move update y increment                                 startX = x; //reset initial values to latest                                 startY = y;                                 invalidate(); //force a redraw                                 break;                 }                 return true; //done with this event so consume it         }          @Override         protected void onDraw(Canvas canvas) {                  // Our move updates are calculated in ACTION_MOVE in the opposite direction                 // from how we want to move the scroll rect. Think of this as dragging to                 // the left being the same as sliding the scroll rect to the right.                 int newScrollRectX = scrollRectX - (int)scrollByX;                 int newScrollRectY = scrollRectY - (int)scrollByY;                  // Don't scroll off the left or right edges of the bitmap.                 if (newScrollRectX < 0)                         newScrollRectX = 0;                 else if (newScrollRectX > (bmLargeImage.getWidth() - displayWidth))                         newScrollRectX = (bmLargeImage.getWidth() - displayWidth);                  // Don't scroll off the top or bottom edges of the bitmap.                 if (newScrollRectY < 0)                         newScrollRectY = 0;                 else if (newScrollRectY > (bmLargeImage.getHeight() - displayHeight))                         newScrollRectY = (bmLargeImage.getHeight() - displayHeight);                  // We have our updated scroll rect coordinates, set them and draw.                 scrollRect.set(newScrollRectX, newScrollRectY,                         newScrollRectX + displayWidth, newScrollRectY + displayHeight);                 Paint paint = new Paint();                 canvas.drawBitmap(bmLargeImage, scrollRect, displayRect, paint);                  // Reset current scroll coordinates to reflect the latest updates,                 // so we can repeat this update process.                 scrollRectX = newScrollRectX;                 scrollRectY = newScrollRectY;         } } } 

Answer 1

You dont call setContentView in fragments, in fact you need to return a View from onCreateView.

Try replacing:

setContentView(new SampleView(this)); 

With this:

return new SampleView(this); 

Answer 2

Return the view instance you want to use:

    @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {         return inflater.inflate(R.layout.ads_tab, container, false);     }
