RecyclerTouchListener overclicks the button in recyclerview

Question

I have a recyclerview that has image, texts & image button, when I use the RecyclertouchListener and add onItemTouchListener it overclicks the button while the button has onclicklistener

If I don't handle clicklistener for the recyclerview, the button works fine. Only when the recyclerview has something to do in the onItemtouchListener.

public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener{

private GestureDetector gestureDetector;
ClickListener clickListener;

public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener)
{

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

        @Override
        public void onLongPress(MotionEvent e) {

            View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if(child != null && clickListener != null)
                clickListener.onLongClick(child, recyclerView.getChildAdapterPosition(child));

        }

    });

}

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
    View child = rv.findChildViewUnder(e.getX(), e.getY());
    if(child != null && clickListener != null && gestureDetector.onTouchEvent(e))
        clickListener.onClick(child, rv.getChildAdapterPosition(child));
    return false;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {

}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}

recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getActivity(), recyclerView, new ClickListener() {
        @Override
        public void onClick(View view, int position) {
            startActivity(new Intent(getActivity(), Show.class).putExtra("show", data.get(position)));
        }

        @Override
        public void onLongClick(View view, int position) {

        }
    }));

Answer 1

So for the RecyclerTouchListener there is no way I found to change the focus from the recyclerview to the button. As the onInterceptTouchEvent steals the focus of the viewgroup to perform the onclick, which means it steals the whole focus on the touch to make its child perform the click which is the recyclerview here. So anything inside the recyclerview can't intercept.

For more explanation try to search on how the onInterceptTouchEvent works from passing false when you tap on the window then false for the viewgroup then the recyclerview which calls the viewgroup onInterceptTouchEvent to apply the onclick. Also I could't adjust the scale of the child (recyclerview).

So I found a solution for the second way to implement onclick for the itemview in the recycleradapter class & I made it could be called from outside the adapter.

Thanks Tara for inspiring a little. Here's is the reference [http://alexzh.com/tutorials/recyclerview-click-listener/][1]

Her's the code I modified

1- Add Interface for the click

public interface ClickListener {

public void onClick (View view, int  position);

public void onLongClick (View view, int  position);

}

2- In Class RecyclerAdapter add method setClickListener

public void setClickListener(ClickListener _clickListener) {
    this.clickListener = _clickListener;
}

3- Call the clickListener.onClick & onLongClick in onBindViewHolder

@Override
public void onBindViewHolder(final HawkViewHolder holder, final int position) {

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                clickListener.onClick(view, holder.getPosition());
            }
        });

        holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View view) {
                clickListener.onLongClick(view, holder.getPosition());
                return true;
            }
        });

4- Call the method recyclerAdapter.setClickListener in the activity

        recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
    recyclerAdapter = new CustomRecyclerAdapter(this);
    recyclerView.setAdapter(recyclerAdapter);
    recyclerAdapter.setClickListener(new ClickListener() {
        @Override
        public void onClick(View view, int position) {

        }

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

Answer 2

Add onClick listener in RecyclerAdapter some thing like this. You can take help from this

final int position=i;
    ListRowHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(mContext,"Recycler Click"+position+myTitle,Toast.LENGTH_SHORT).show();

            Intent intent=new Intent(mContext,ItemDetails.class);
            intent.putExtra("itemName",myTitle);
            mContext.startActivity(intent);
        }
    });
