Tutaj tworzę własny listview z checkbox / RadioButton. Mam to, ale potrzebuję tylko jednego wyboru.

Próbuję tego użyćlstvw.setChoiceMode(ListView.CHOICE_MODE_SINGLE); ale dla mnie to nie działa. Czy są na to jakieś inne rozwiązania?

main.java

  private ImageAdapter  adapter; 

private static String month[] = {"January","February","March","April","May",  
    "June","July","August","September",  
    "October","November","December"};  


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ListView lstvw = (ListView) findViewById(R.id.listView);

     adapter = new ImageAdapter(this, month);  
     lstvw.setAdapter(adapter);  
      lstvw.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

     lstvw.setOnItemClickListener(this);
}

Nie mam pojęcia, jak dodać kod do pola wyboru w klasie adaptera. Sprawdź klasę adaptera jak poniżej.

ImageAdapter.class

public class ImageAdapter extends BaseAdapter{

public String title[];  
public String description[];  
public Activity context;  
public LayoutInflater inflater;

public ImageAdapter(Activity context,String[] title) {  
    super();  

    this.context = context;  
    this.title = title;  

    this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);  
}  

@Override  
public int getCount() {  
    // TODO Auto-generated method stub  
    return title.length;  
}  

@Override  
public Object getItem(int position) {  
    // TODO Auto-generated method stub  
    return null;  
}  

@Override  
public long getItemId(int position) {  
    // TODO Auto-generated method stub  
    return 0;  
}  

public static class ViewHolder  
{  

    TextView txtViewTitle;  

}  

@Override  
public View getView(int position, View convertView, ViewGroup parent) {  
    // TODO Auto-generated method stub  

    ViewHolder holder;  
    if(convertView==null)  
    {  
        holder = new ViewHolder();  
        convertView = inflater.inflate(R.layout.listitem, null);  

        holder.txtViewTitle = (TextView) convertView.findViewById(R.id.lstvw_textView);  
        convertView.setTag(holder);  
    }  
    else  
        holder=(ViewHolder)convertView.getTag();  

    holder.txtViewTitle.setText(title[position]);  

    return convertView;  
}   

}
