How to disable IOnTouchListener

Shay Wilner 1,746

Hello

I implemented a class GameAreaTouchListener to detect if i touch a relative layout called gamearea;

class GameAreaTouchListener:Java.Lang.Object ,RelativeLayout.IOnTouchListener
        {
            public GameAreaTouchListener(RelativeLayout rl )
            {
                Gamearea = rl;
             }
            private RelativeLayout Gamearea { get; }
             public bool OnTouch(View v, MotionEvent e)

            {

                switch (e.ActionMasked)
                {
                    case MotionEventActions.Up:
                               //blablabla   

                        }
                            break;
                }
                return true;
            }
        }

i have two buttons

private void Button1_Click(object sender, System.EventArgs e)
//  i  create an instance of class  GameAreaTouchListener
        {
            gat = new GameAreaTouchListener(gamearea);
           gamearea.SetOnTouchListener(gat);

        }


 private void Button2_Click(object sender, System.EventArgs e)
            {


            }

When i click Button2 i would like to disable OnTouch(View v, MotionEvent e) of GameAreaTouchListener ?

Thanks

Hello,

Welcome to our Microsoft Q&A platform!

Android.Views.View class doesn't provide the method to remove the onTouchListener. A workaround is to set another touchListener to the view instead and do nothing in the OnTouch event.

Here is the sample code, you could refer to it.

   private void Button2_Click(object sender, System.EventArgs e)  
   {  
       gamearea.SetOnTouchListener(new DoNothing_TouchListener());  
   }  
     
     
   class DoNothing_TouchListener : Java.Lang.Object, IOnTouchListener  
   {  
       public bool OnTouch(View v, MotionEvent e)  
       {  
           return false;  
       }  
   }

Best Regards,
