If you really thinking how to starting game development, then it is useful for you.This is simple example of how to find the co-ordinate of layout in Android.This is not a big idea, but more developer want to find their position of finger touch in view.

Here is the some code:

  tv = new TextView(this);



  tv.setText("Drag By One Finger");

  tv.setOnTouchListener(this);

  setContentView(tv);

 }



 @Override

 public boolean onTouch(View v, MotionEvent event) {

  sb.setLength(0);

  switch (event.getAction()) {

  case MotionEvent.ACTION_DOWN:

   sb.append("Down, ");

   break;

  case MotionEvent.ACTION_MOVE:

   sb.append("Move, ");

   break;

  case MotionEvent.ACTION_CANCEL:

   sb.append("Cancel ,");

   break;

  case MotionEvent.ACTION_UP:

   sb.append("Up, ");

   break;

  }

  sb.append(event.getX());

  sb.append(",");

  sb.append(event.getY());

  String test=sb.toString();

  Log.d("TAG", "Testing->"+test);

  tv.setText(test);

  return true;

 }

}
