Resize View in WindowManager in android

Question

I would like to re-size my view which is created using service in Windowmanager on touch I have changed height and width it is working properly.

But I have found that params.x and params.y is not changing so it is moving at the time of resizing the view.

And for that I found this values for different situation

• when view is small and at top left params.x = -310 params.y = -826

• when view is small and at bottom left params.x = -364 params.y = 958

• when view is big and at top left params.x = -253 params.y = -657

• when view is big and at bottom left params.x = -323 params.y = 888

  and this is my code of ontouch

                      case MotionEvent.ACTION_DOWN:
                          initialX = params.width;
                          initialY = params.height;
                          initialTouchX = event.getRawX();
                          initialTouchY = event.getRawY();
                          Log.w("DOWN","X="+params.x+" Y="+params.y);
                          return true;
  
                      case MotionEvent.ACTION_MOVE:
                          params.width = (int) (initialX + (int) (event.getRawX() - initialTouchX));
                          params.height = (int) (initialY + (int) (event.getRawY() - initialTouchY));
                          Log.w("MOVE","X="+params.x+" Y="+params.y);
                          windowManager.updateViewLayout(videoLoder, params);
                          return true;
  

• How to get params.x and params.y as change in the height and width ?

• And how this params.x and params.y is calculated?

I have found the some sort of similar question but answered yet.

Answer 1

I have set gravity to center so this issue was raised but after seting gravity to top left all working like charm

params.gravity = Gravity.TOP | Gravity.LEFT;

Might be helpful to some one
