RecyclerView 單擊偵聽器

public  class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {

    private GestureDetector gestureDetector;
    private RecyclerTouchListener.ClickListener clickListener;

    public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final RecyclerTouchListener.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.getChildPosition(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.getChildPosition(child));
        }
        return false;
    }

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

    }

    @Override
    public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

    }

    public interface ClickListener {
        void onLongClick(View child, int childPosition);

        void onClick(View child, int childPosition);
    }
}

在 MainActivity 中

RecyclerView recyclerView =(RecyclerView) findViewById(R.id.recyclerview);
 recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getActivity(),recyclerView, new RecyclerTouchListener.ClickListener() {
      @Override
      public void onLongClick(View child, int childPosition) {

      }

      @Override
      public void onClick(View child, int childPosition) {

       
     }
    }));
