从一个警示框中点击获取值

Question

程序中的警示框中有一个 channels 列表。
我想从 channels 点击中获取值。

 public void ShowChannelDialog(){
      String[] channels = new String[_publicChannels.size()];
      channels = _publicChannels.toArray(channels);
      AlertDialog.Builder showChannel = new AlertDialog.Builder(this);
      showChannel.setTitle("Channel List ("+(_publicChannels.size()-1)+" channels)");
      showChannel.setItems(channels, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            _publicChannels.clear();
            if (item == (_publicChannels.size())) {
                System.out.println("NEW CHANNEL");
                CreateNewChannel();
                dialog.dismiss();
            }else{
                String channel = String.valueOf(item);
                System.out.println("Selected: " + channel);
            }
        }
    });

String.valueof(item) 只在数组中给出一个int值，我想获取实际的text值。
如何实现？谢谢！
