onFling不起作用

Question

I have a ViewPager which holds a RecyclerView I add a OnTouchListener to an image view inside the RecyclerView 's item, trying to detect touches using GestureDetector.SimpleOnGestureListener but I can't get the onFling events. I suspect it's happening because either the RecyclerView or the ViewPager catching the motion event. How do I fix it?
My code (though it's pretty simple):

public class MyClickListener extends GestureDetector.SimpleOnGestureListener{

public MyClickListener(){

}

@Override
public boolean onDown(MotionEvent e) {
    return false;
}

@Override
public void onShowPress(MotionEvent e) {
    // TODO Auto-generated method stub
    Log.d("aaa", "show press");
}

@Override
public boolean onSingleTapUp(MotionEvent e) {
    Log.d("aaa", "tapup");
    return false;
}

@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
        float distanceY) {
    // TODO Auto-generated method stub
    Log.d("aaa", "scroll");
    return false;
}

@Override
public void onLongPress(MotionEvent e) {
    // TODO Auto-generated method stub
    Log.d("aaa", "long press");
}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
        float velocityY) {
    // TODO Auto-generated method stub
    Log.d("aaa", "fling");
    return false;
}

setting the oun touch:

public VoiceItemHolder(View view, GestureDetector.OnGestureListener listener) {
    super(view); 

    icon = (CircleButton) view.findViewById(R.id.icon_iv);
    touchListener = new GestureDetectorCompat(view.getContext(), listener);

    icon.setOnTouchListener(this);

}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if (touchListener != null)
        touchListener.onTouchEvent(event);
    return false;
}

Feeling a bit awkward to answer my own question :)
If you have a view in a view group and you want to get onFling 's on the inner view you should override the onInterceptTouchEvent of the view group and return false
