Xamarin Android-带有图标的条目-SetCompoundDrawableSwithinInstincBounds-触摸/点击事件？

我想用右边的图标进入

我使用Xamarin表单+PCL

我已经在IOS和Android中实现了主要部分

我在条目中添加了图标，这看起来棒极了

但是！ 我需要捕捉当用户点击这个图标

在Ios中，我做的很简单…但是Android。。我不能做这件事(((

Droid自定义渲染以供输入

  FormsEditText editText = Control;
            if(!string.IsNullOrEmpty(element.Image))
            {            
                Drawable d = GetDrawable(element.Image);

                switch(element.ImageAlignment)
                {
                    case ImageAlignment.Left:
                         editText.SetCompoundDrawablesWithIntrinsicBounds(d, null, null, null);
                        break;

                    case ImageAlignment.Right:
                        editText.SetCompoundDrawablesWithIntrinsicBounds(null, null, d, null);
                        break;
                }
            }


 private BitmapDrawable GetDrawable(string imageEntryImage)
        {
            int resID = Resources.GetIdentifier(imageEntryImage, "drawable", Context.PackageName);
            Android.Graphics.Drawables.Drawable drawable = ContextCompat.GetDrawable(Context, resID);
            Bitmap bitmap = ((BitmapDrawable)drawable).Bitmap;
            var im =  new BitmapDrawable(Resources, Bitmap.CreateScaledBitmap(bitmap, element.ImageWidth * 4, element.ImageHeight * 4, true));
            return im;
        }

protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
    {
        base.OnElementChanged(e);

        if (Control != null)
        {
           //Resource.Drawable.ic_action_info is your image resId
            Control.SetCompoundDrawablesRelativeWithIntrinsicBounds(Resource.Drawable.ic_action_info, 0, 0, 0);
            Control.SetOnTouchListener(new OnDrawableTouchListener());
        }
    }
    public class OnDrawableTouchListener : Java.Lang.Object, Android.Views.View.IOnTouchListener
    {
        public bool OnTouch(Android.Views.View v, MotionEvent e)
        {
            if (v is EditText && e.Action == MotionEventActions.Up)
            {
                EditText editText = (EditText)v;
                editText.SetCompoundDrawablesRelativeWithIntrinsicBounds(Resource.Drawable.ic_action_info, 0, 0, 0);
                if (editText.GetCompoundDrawables()[0] != null)
                {
                    //If the region on which i tapped is the region with the icon
                    if (e.RawX <=editText.GetCompoundDrawables()[0].Bounds.Width())
                    {
                        Toast.MakeText(v.Context,"icon",ToastLength.Short).Show();
                        return true;
                    }
                }
            }

            return false;
        }
    }

因此，我需要捕获此图标上的点击/触摸事件

多谢各位
