Can I get the value of MotionEvent.getRawX()/getRawY() of other pointers ?
MotionEvent.getRawX() api reference
The api says that uses getRawX/getRawY to get original raw X/Y coordinate, but it only for 1 pointer(the last touched pointer), is it possible to get other pointer's raw X/Y coordinate ?
Indeed, the API doesn't allow to do this, but you can compute it. Try that :
public boolean onTouch(final View v, final MotionEvent event) {
int rawX, rawY;
final int actionIndex = event.getAction() >> MotionEvent.ACTION_POINTER_ID_SHIFT;
final int location[] = { 0, 0 };
v.getLocationOnScreen(location);
rawX = (int) event.getX(actionIndex) + location[0];
rawY = (int) event.getY(actionIndex) + location[1];
}
