Click button inside row in StaggeredGrid RecyclerView causes whole item to click

Hi I have a button inside a row RecyclerView

(for a bookmark). When I click on a button, it calls that button as well as itemclick for the entire row. I have separate code to handle clicks of a button and the whole element. Why does a button in a row cause the entire element to be clicked?

How can I fix this problem?

Here is my code for a mouse click inside the adapter:

viewHolder.imgBookmark.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        ...
    }
});

      

        
        
        
      

    

Here is my code for clicking on the RecyclerView item:

mGridView.addOnItemTouchListener(new RecyclerItemClickListener(
        getActivity(), mGridView,
        new RecyclerItemClickListener.OnItemClickListener() {
    @Override
    public void onItemClick(View view, int position) {
        ...
    }

    @Override
    public void onItemLongClick(View view, int position) {
        ...
    }
}));

      

        
        
        
      

    

RecyclerItemClickListener.java

public class RecyclerItemClickListener implements
    RecyclerView.OnItemTouchListener {
    public static interface OnItemClickListener {
        public void onItemClick(View view, int position);

        public void onItemLongClick(View view, int position);
    }

    private OnItemClickListener mListener;
    private GestureDetector mGestureDetector;

    public RecyclerItemClickListener(Context context,
            final RecyclerView recyclerView, OnItemClickListener listener) {
        mListener = listener;

        mGestureDetector = new GestureDetector(context,
                new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }

            @Override
            public void onLongPress(MotionEvent e) {
                View childView = recyclerView.findChildViewUnder(
                        e.getX(), e.getY());

                if (childView != null && mListener != null) {
                    mListener.onItemLongClick(childView,
                            recyclerView.getChildPosition(childView));
                }
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(), e.getY());

        if (childView != null && mListener != null
                && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView, view.getChildPosition(childView));
        }

        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
    }
}
