How to get item from RecyclerView adapter in Android

Question

In old code when I was using ListView with custom adapter I could get item with this code.

Message msg = (Message) adapter.getItem(poistion);

Now I am implementing RecyclerView. How can I get item from RecyclerView.adapter?

You have to implement it yourself.

Add a new method in your custom Adapter and you are done.

public Message getItem(int position) {
  return messageList.get(position);
}

Yeah of course.. but in order to have `Message` object as return value you need to set the List of items as `List mItems;` in your adapter. – Davideas May 05 '15 at 12:44

I think the correct way to getItem() is through RecyclerView LayoutManager.

View v = recyclerView.getLayoutManager().findViewByPosition(position);

This how to get the view, not the data backing the view. – Bryan Bryce Mar 10 '16 at 16:51

@PhoenixFF true, but if you have EditTexts as items, this is the best method to get their value (after it was changed by the user)! :) – Willi Mentzel Aug 08 '16 at 20:00

How do you get the data from the view? (assume it has a TextView named 'tv') – john k Oct 10 '18 at 18:09
@johnktejik when you get the view by using above method then you can get any view attribute like view.textView.gettext() – Vikas Oct 20 '21 at 15:37

Onclicklistener did the trick

public class MainActivity extends AppCompatActivity {

    Context context;
    RecyclerView recyclerView;
    RelativeLayout relativeLayout;
    RecyclerView.Adapter recyclerviewAdapter;
    RecyclerView.LayoutManager recyclerViewLayoutManager;
    String[] numbers = { "ANDROID",

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        relativeLayout = (RelativeLayout)findViewById(R.id.relativelayout1);
        recyclerView = (RecyclerView)findViewById(R.id.recyclerview1);

        recyclerviewAdapter = new RecyclerViewAdapter(context,numbers);
        recyclerView.setAdapter(recyclerviewAdapter);



    }


    public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {

        String[] numvalues;

        }

        public  class ViewHolder extends RecyclerView.ViewHolder{

public frames getItem(int position) {
  return rv_list_frames.get(position);

This will return the View but not the item. – MarioNoll Apr 25 '19 at 13:58
