Pinch Gesture Not Working on Android about xamarinformsgesture

[yonkahlon]

Just as a reference, here is my workaround:

private MotionEvent? _pinchInitialDown;
public void OnUp(MotionEvent? e)
{
    if(e != null)
        PanAction?.Invoke(e, e);

    _pinchInitialDown = null;
}

public override bool OnScroll(MotionEvent? initialDown, MotionEvent? currentMove, float distanceX, float distanceY)
{
    if (currentMove != null && initialDown != null)
    {
        if (_pinchInitialDown == null && initialDown.PointerCount == 1 && currentMove.PointerCount == 2)
        {
            _pinchInitialDown = MotionEvent.Obtain(currentMove);
        }

        if(currentMove.PointerCount == 1 && PanAction != null)
            return PanAction.Invoke(initialDown, currentMove);

        if (currentMove.PointerCount == 2 && PinchAction != null && _pinchInitialDown != null)
        {
            PinchAction.Invoke(_pinchInitialDown, currentMove);
            return true;
        }
    }
    return false;
}
