Question

Why OnTouchEvent in Mono for Android doesn’t have the View argument OnTouch has in Android for Java? How can I get the view that’s firing the event?

I’m trying to do something as the drag and zooming examples here.

Thanks in advance.

Answer 1

The method you’re looking at is Activity.OnTouchEvent which looks the same as it does in Java. The example you’re looking at is actually using the OnTouchListener.onTouch method, which in Mono For Android maps to IOnTouchListener.OnTouch. A basic class definition that implemented this inferface would look something like:

public class Touch : Activity, View.IOnTouchListener
{
    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);
    }

    public bool OnTouch(View v, MotionEvent e)
    {
        return true;
    }
}
