Android Recycler - OnClickListener called when clicking everywhere


I have a simple adapter on a recycler view and a simple xml layout for inflation. In the xml i have 2 textviews and i register an onClickListener only to the first. But when i click to the second textview, the listener is called again. Anywhere i click the listener is called.

Any ideas? Thank you

MyRecyclerViewAdapter

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

private List<String> mData;
private LayoutInflater mInflater;
private ItemClickListener mClickListener;
private RecyclerView rv;

// data is passed into the constructor
MyRecyclerViewAdapter(Context context, List<String> data,RecyclerView rv) {
    this.mInflater = LayoutInflater.from(context);
    this.mData = data;
}

// inflates the row layout from xml when needed
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = mInflater.inflate(R.layout.test, parent, false);
    return new ViewHolder(view);
}

// binds the data to the TextView in each row
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    String animal = mData.get(position);
    holder.myTextView.setText(animal);
}

// total number of rows
@Override
public int getItemCount() {
    return mData.size();
}


// stores and recycles views as they are scrolled off screen
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    TextView myTextView;

    ViewHolder(View itemView) {
        super(itemView);
        myTextView = itemView.findViewById(R.id.tvAnimalName);
         itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("Item","clicked");
            }
        });

    }


}

// convenience method for getting data at click position
String getItem(int id) {
    return mData.get(id);
}
}`

Test Layout

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="82dp">

    <TextView
        android:id="@+id/tvAnimalName"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:text="Hello World Ankit"
        android:textSize="24sp"

Solution

  • Change this :

    // stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView myTextView;
    
        ViewHolder(View itemView) {
            super(itemView);
            myTextView = itemView.findViewById(R.id.tvAnimalName);
             itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Log.d("Item","clicked");
                }
            });
    
        }
    
    
    }
    

    To:

    // stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView myTextView;
    
        ViewHolder(View itemView) {
            super(itemView);
            myTextView = itemView.findViewById(R.id.tvAnimalName);
             myTextView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Log.d("Item","clicked");
                }
            });
    
        }
    
    
    }
