Question

I have a listview and custom layout consisting of TextView, ImageView, ImageButton. I want my image button to behave like RadioButton. But my onListItemClick event is not getting invoked.

public class MyListAdapter extends BaseAdapter {

    Context context;
    ArrayList<String> text;
    ArrayList<String> Count;

    int count;

    public MyListAdapter(Context ctx, ArrayList<String> text, ArrayList<String> Count) {
        this.context = ctx;
        this.textAnswers = text;
        this.optionCount = Count;
    }

    @Override
    public int getCount() {
        return Count.size();
    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        if(convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.custom_layout, null);
        }

        ImageButton choice = (ImageButton)convertView.findViewById(R.id.ImageButton);
        if(imageChoice != null) {
            choice.setImageResource(R.drawable.radio_unselected);

        }

        TextView txt = (TextView)convertView.findViewById(R.id.TextView);
        txt.setText(Count.get(position));

        TextView txtText = (TextView)convertView.findViewById(R.id.TextViewAnswer);
        txtText.setText(textAnswers.get(position));

        return convertView;
    }
}

And my onListItemClick as,

@Override
protected void onListItemClick(ListView listView, View v, int position, long id) {
    super.onListItemClick(listView, v, position, id);
    ImageButton choice = (ImageButton)v.findViewById(R.id.ImageButton);
    choice.setImageResource(R.drawable.radio_selected); 
}

Now plz any one help to give my imagebutton the behavior like radiobutton. Most important i missed is that my onListItemClick is not getting invoked.
Also I have set the android:focusable=”false” android:focusableInTouchMode=”false” android:clickable=”false” of all controls on my custom_layout.
Thanks in advance.

You need to add a setOnItemClickListener to your ListView in the main activity, if you do not, you’ll never get a call to the itemClick.

for instance:

OnCreate() Method:

ListView lv = (ListView) findViewById(R.id.listview1);

lv.setOnItemClickListener(this);

// Create the method below and let the activity implement onitemclicklistener

public void onItemClick(AdapterView<?> a, View v, int position, long id) {
//set action here
 }

that should work 🙂
