自定义ArrayAdapter不工作？

这是我的代码工作，试图添加别的东西，然后发现我以前的代码已停止工作的情况之一。程序启动时崩溃。这个错误似乎与ArrayAdapter自定义类的定义有关，就像我尝试使用内置适配器一样，它工作正常。任何帮助？自定义ArrayAdapter不工作？

public class MainEntry extends ListActivity{  

private String[] items = {"yay","yay2","asdfa","nlah","lipsum","orum","rawr"}; 



/** Called when the activity is first created. */ 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setListAdapter(new IconicAdapter()); 
} 


class IconicAdapter extends ArrayAdapter { 
    IconicAdapter(){ 
     super(MainEntry.this, R.layout.post_obj, items); 
    } 

    public View getView(int pos, View convertView, ViewGroup parent){ 
     LayoutInflater inf = getLayoutInflater(); 

     View row = null; 
     if(convertView==null){ 
      inf.inflate(R.layout.post_obj, parent, false); 
     }else{ 
      row = convertView; 
     } 
     inf.inflate(R.layout.post_obj, parent, false); 

     TextView label = (TextView) row.findViewById(R.id.label); 
     label.setText(items[pos]); 

     ImageView image = (ImageView) row.findViewById(R.id.icon); 
     image.setImageResource(((Math.random()>.5)?R.drawable.wolfire:R.drawable.android)); //temp 

     return row; 
    } 

}

}

这里的logcat的日志，如果有帮助：

您可以详细说明什么现在不起作用，或者您使用上述代码看到了什么？ – 2009-12-30 04:02:03

啊，对不起。它只是在启动时关闭。 – GuyNoir 2009-12-30 04:40:43

考虑添加注释和JavaDoc，特别是如果您发布代码以供其他人阅读。其次，编写单元测试。这将帮助您检测行为变化。 – 2009-12-30 09:39:22

唉唉......我是这样一个白痴。大声笑。我没有真正将'row'设置为inf.inflate（）的值。

Facepalm是的。忽视这一点。希望别人能够找到有用的代码。

你是对的（row = inf.inflate ...），你应该有一个NullPointerException。另外，你必须删除第二个电话inf.inflate(R.layout.post_obj, parent, false);。否则，您将失去由convertView授予的优化...
