You're seeing the default implementation of [`toString()`](https://stackoverflow.com/questions/3615721/how-to-use-the-tostring-method-in-java) - Override it and change it to something more useful — PPartisan, Mar 21 '19 at 15:18

To fully customize the way you want to display your data, you can override the ArrayAdapter definition to create yours.

Custom layout : item_bean.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="horizontal" >
    <!-- Here, you can display index for example -->
    <TextView
      android:id="@+id/tvIndex"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:style="@style/styleIndex" />
    <TextView
      android:id="@+id/tvName"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:style="@style/styleName" /> <!-- You can use your own style -->
</LinearLayout>

Custom Adapter: BeansAdapter

public class BeansAdapter extends ArrayAdapter<Bean> {
    public UsersAdapter(Context context, ArrayList<Bean> beans) {
       super(context, 0, beans);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
       // Get the data item for this position
       Bean bean = getItem(position);    
       // Check if an existing view is being reused, otherwise inflate the view
       if (convertView == null) {
          convertView = LayoutInflater.from(getContext()).inflate(R.layout.item_bean, parent, false);
       }
       // Lookup view for data population
       TextView tvIndex = (TextView) convertView.findViewById(R.id.tvIndex);
       TextView tvName = (TextView) convertView.findViewById(R.id.tvName);
       // Populate the data into the template view using the data object
       tvIndex.setText(position);
       tvName.setText(bean.getName());
       // Return the completed view to render on screen
       return convertView;
   }
}
