Android - 仅在适配器中显示Spinner的值1

我有一个微调控件，我从一个继承自BaseAdapter的类中填充。我可以使用这个适配器类来填充微调，但它显示2列，我只喜欢一个。例如，它目前显示：Android - 仅在适配器中显示Spinner的值1

而且我也喜欢，只显示：

下面是我的适配器代码：

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; 
    } 
}

并填充码spinner：

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

DBA dapter.queryAll（）返回一个POCInfo类型的列表。 POCInfoAdapter类也被许多其他需要电子邮件地址的活动使用，因此我不能只是将getView（）更改为仅返回FullName。

任何想法？

删除此行holder.txtEmailAddress =（TextView的）view.findViewById（R.id.txtEmailAddress）膨胀该布局; – 2012-03-07 16:03:59

正如我在OP的第二行到最后一行所说的那样，我无法更改getView，因为这个类在其他需要的活动中使用。 – Robert 2012-03-07 16:06:14

...然后创建一个类的副本，并将其删除并使用该...或有一个标志，将隐藏它，并相应地设置该标志 – jsimpson 2012-03-07 16:07:41

无论您要显示多少项目（包括单选按钮），都可以在您的自定义布局中对其进行配置。并且可以由代码

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