long downTime = SystemClock.uptimeMillis();
final MotionEvent downEvent = MotionEvent.obtain(downTime, downTime,
MotionEvent.ACTION_DOWN, x, y, 0);
//downTime += 2500;
final MotionEvent upEvent = MotionEvent.obtain(downTime, downTime,
MotionEvent.ACTION_UP, x, y, 0);
//	        view.onTouchEvent(downEvent);
//	        view.onTouchEvent(upEvent);
view.dispatchTouchEvent(downEvent);
view.dispatchTouchEvent(upEvent);
downEvent.recycle();
upEvent.recycle();
