示例1: SwapTouchEvent
private MotionEvent SwapTouchEvent(MotionEvent ev)
{
float width = Width;
float height = Height;
float swappedX = (ev.GetY() / height) * width;
float swappedY = (ev.GetX() / width) * height;
ev.SetLocation(swappedX, swappedY);
return ev;
}示例2: OnTouchEvent
public override bool OnTouchEvent (MotionEvent e)
{
UpdateSourcePartial();
// The logic below is mostly copied from the parent class, since we
// can't update private mBounds variable.
