How do I get the position selected in a RecyclerView?

Question

I am experimenting with the support library\'s recyclerview and cards. I have a recyclerview of cards. Each card has an \'x\' icon at the top right corner to remove it:

Answer 1

1. Create class Name RecyclerTouchListener.java

import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;

public class RecyclerTouchListener implements RecyclerView.OnItemTouchListener 
{

private GestureDetector gestureDetector;
private 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) {

}

public interface ClickListener {
    void onClick(View view, int position);

    void onLongClick(View view, int position);
}
}

2. Call RecyclerTouchListener

recycleView.addOnItemTouchListener(new RecyclerTouchListener(this, recycleView, 
new RecyclerTouchListener.ClickListener() {
    @Override
    public void onClick(View view, int position) {
        Toast.makeText(MainActivity.this,Integer.toString(position),Toast.LENGTH_SHORT).show();
    }

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

    }
}));
