Making a RecyclerView interactive

Question

How do I implement an OnClickListener on a RecyclerView??

Online tutorials show the implementation of OnItemTouchListener, but they are a little vague. Could someone show the code for a simple implementation of touch interaction with a RecyclerView.

One article i came across : http://sapandiwakar.in/recycler-view-item-click-handler/

This provides a vague picture of how to go about it, but could someone make things clear. Thanks.

If you are using custom adapter then you can use OnClickListener method like this in your Holder class.

public class DataObjectHolder extends RecyclerView.ViewHolder {
        TextView header , resp_id , time;
        ImageView status,info,delete,upload;

        public DataObjectHolder(View itemView) {
            super(itemView);
            header = (TextView) itemView.findViewById(R.id.header_text_inc);
            resp_id = (TextView) itemView.findViewById(R.id.resp_text_inc);
            time = (TextView) itemView.findViewById(R.id.time_text_inc);
            delete =(ImageView)itemView.findViewById(R.id.delete_inc_image);
        Log.e(LOG_TAG, "Adding Listener");



            itemView.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub

                   // do something here                 
                }
            });
        delete.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                r_bean = mDataset.get(getAdapterPosition());

            }
        });

How do I get the content pertaining to the childView clicked, in the onClick. — Arjun Issar, Aug 18 '15 at 12:49
You can find them using itemView.findViewById(R.id.something) and set OnClickListener on them. — SRB Bans, Aug 18 '15 at 12:52

For RecyclerView item OnItemTouchListener is best way

But you can do it click on Item by following in adpter

 @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
    ...
    holder.itemView.setOnClickListener(..)
    ...
 }

For swipe on RecyclerView

 ItemTouchHelper.SimpleCallback simpleItemTouchCallback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {

        @Override
        public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder viewHolder1) {
            return false;
        }

        @Override
        public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
            //Remove swiped item from list and notify the RecyclerView

            if (swipeDir == ItemTouchHelper.LEFT) {
                Snackbar.make(recyclerViewCards, getString(R.string.item_deleted),
                        Snackbar
                                .LENGTH_LONG)
                        .show();
                showVisitingCardsPresenterImpl.detletCardFromRealm(Realm.getInstance
                                (ShowVisitingCardsActivity.this), mAdapter.getID(viewHolder
                                .getAdapterPosition()), viewHolder
                                .getAdapterPosition()
                );

            } else {
                showVisitingCardsPresenterImpl.startVisitingCardUpdateActivity(mAdapter.getID(viewHolder
                        .getAdapterPosition()));
            }
        }
    };

Could you elaborate on the implementation of OnItemTouchListener? — Arjun Issar, Aug 18 '15 at 12:03

You can use holder.root for item click in the customadapter

 @Override
    public void onBindViewHolder(final MyAdapter.ViewHolder1 holder,  final int position) {

    holder.root.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
         //write your code here
        }         
    });

}

and you have to use this

 mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {


       @Override
       public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) {
           child = recyclerView.findChildViewUnder(motionEvent.getX(),motionEvent.getY());


           if(child!=null && mGestureDetector.onTouchEvent(motionEvent)){
               //Drawer.closeDrawers();
        //write your code here

               return true;
           }             

           if(txt!=null)
           {


       }
       });
