Question

I am trying to set a row to bold on clicking it. But it gives me a ClassCastException when I try to convert view into TextView like the following –

setListAdapter(adapter);
final ListView lv = getListView();
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
  int position, long id) {
            TextView tv = (TextView)view;
            tv.setTypeface(null, Typeface.BOLD);
        }
        });

What am I doing wrong? How should I go about it?

EDIT:

My adapter looks like –

public class CountryListAdapter extends ArrayAdapter<String> {
private final Activity context;
private final ArrayList<String> names;

public CountryListAdapter(Activity context, ArrayList<String> names) {
    super(context, R.layout.rowlayout, names);
    this.context = context;
    this.names = names;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = context.getLayoutInflater();
    View rowView = inflater.inflate(R.layout.rowlayout, null, true);
    TextView textView = (TextView) rowView.findViewById(R.id.label);
    textView.setText(names.get(position));

    return rowView;
}
}

Your adapter code shows the main cause of failure:

According to your adapter code the view you cast is the rowView, not the textView.So you should access it also that way. That’s why you get ClassCastException.

 public void onItemClick(AdapterView<?> parent, View view,
 int position, long id) {
        View rowView = view
        TextView tv = (TextView) rowView.findViewById(R.id.label);
        tv.setTypeface(null, Typeface.BOLD);
    }
    });
