Answer 1

I suspect that you want to detect a sideways motion, much like the used for unlocking the screen. To do that, you have to listen for a touch down event, then an up event and compare the coordinates of the two events.

You need to use gestures and gesture listeners( http://developer.android.com/reference/android/gesture/GestureOverlayView.OnGestureListener.html ). The MotionEvent that you obtain in listener contains all the information you need.
