Android-仅在Adapter的Spinner中显示1个值

Question

我有一个微调器控件，它是从继承自BaseAdapter的类中填充的。我可以使用这个适配器类来填充微调器，但它显示了2列，我只想要一列。例如，它目前显示：

John Brown                       [e-mail]
Sue Fields                       [e-mail]
Mark Twain                       [e-mail]

我希望它只显示：

John Brown
Sue Fields
Mark Twain

这是我的适配器的代码：

public class POCInfoAdapter extends BaseAdapter {
    //Private objects.
    private List<POCInfo> mListPOCInfo;
    private LayoutInflater mInflater;
    //constructor.
    public POCInfoAdapter(Context c, List<POCInfo> list){
        mListPOCInfo = list;
        //create layout inflater.
        mInflater = LayoutInflater.from(c);
    }
    @Override
    public int getCount(){
        return mListPOCInfo.size();
    }
    @Override
    public Object getItem(int position){
        return mListPOCInfo.get(position);
    }
    @Override
    public long getItemId(int position){
        return position;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent){
        //Get view reference.
        View view = convertView;
        //If view is null.
        if(view == null){
            //Inflate new layout.
            view = mInflater.inflate(R.layout.poc_list, null);
            //create holder.
            ViewHolder holder = new ViewHolder();
            //Find Controls.
            holder.txtFullName = (TextView)view.findViewById(R.id.txtFullName);
            holder.txtEmailAddress = (TextView)view.findViewById(R.id.txtEmailAddress);
            //Set data structure to view.
            view.setTag(holder);
        }
        //Get selected POC Info.
        POCInfo pocInfo = mListPOCInfo.get(position);
        if(pocInfo != null){
            //query data structure.
            ViewHolder holder = (ViewHolder)view.getTag();
            //Set data to display.
            holder.txtFullName.setText(pocInfo.getFullName());
            holder.txtEmailAddress.setText(pocInfo.getEmailAddress());
        }
        return view;
    }
    //Class to hold data structure on view with POC Information.
    static class ViewHolder{
        private TextView txtFullName;
        private TextView txtEmailAddress;
    }
}

以及填充微调器的代码：

Spinner spSpinner = (Spinner)findViewById(R.id.spPOCs);
spSpinner.setAdapter(new POCInfoAdapter(this, DBAdapter.queryAll()));

queryAll（）返回一个类型为POCInfo的列表。POCInfoAdapter类也被许多其他需要电子邮件地址的活动使用，所以我不能只将getView（）更改为只返回FullName。

有什么想法吗？

无论您想要显示多少项，包括单选按钮，您都可以在自定义布局中配置它们。你可以通过你的代码来扩展这个布局

view = mInflater.inflate(R.layout.poc_list, null);
