How to add Onclick listener to recycler view

You can handle this using two ways

1). Gesture touch

2).Using interface in adapter

I suggest second way using interface

How to use interface for recycleritemclick

public class RecycleViewAdapter extends 
  RecyclerView.Adapter<RecycleViewHolder> {// Recyclerview will extend to
  private List<FileName> fileNames;
  private Context context;

//declare interface 
  private OnItemClicked onClick;

//make interface like this
  public interface OnItemClicked {
        void onItemClick(int position);
  }

  public RecycleViewAdapter(Context context,List<FileName> fileNames) {
    this.context = context;
    this.fileNames = fileNames;
  }

Now assign click to interface

@Override
public void onBindViewHolder(RecycleViewHolder holder, final int position) {
  //............//
  holder.title.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
        onClick.onItemClick(position);
     }
  });
}

At the end of the adapter class up from finishing bracket make one method to assign itemclick to interface

public void setOnClick(OnItemClicked onClick){
    this.onClick=onClick;
}

In MainActivity.java
Bind the item click with adapter

public class MainActivity extends Activity implements OnItemClicked {
 
    private RecyclerView mRecyclerView;
    private CityAdapter mAdapter;
    private List<City> cities;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_city);

        mRecyclerView = (RecyclerView)findViewById(R.id.list);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        
        mAdapter = new CityAdapter(cities, R.layout.row_city, this);
        mRecyclerView.setAdapter(mAdapter);
 
        mAdapter.setOnClick(MainActivity.this); // Bind the listener
    }
 
    @Override
    public void onItemClick(int position) {
    // The onClick implementation of the RecyclerView item click
    //ur intent code here
    }
}
