自定義ArrayAdapter不工作？

這是我的代碼工作，試圖添加別的東西，然後發現我以前的代碼已停止工作的情況之一。程序啓動時崩潰。這個錯誤似乎與ArrayAdapter自定義類的定義有關，就像我嘗試使用內置適配器一樣，它工作正常。任何幫助？自定義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; 
    } 

}

}

這裏的logcat的日誌，如果有幫助：

您可以詳細說明什麼現在不起作用，或者您使用上述代碼看到了什麼？ – 2009-12-30 04:02:03

啊，對不起。它只是在啓動時關閉。 – GuyNoir 2009-12-30 04:40:43

考慮添加註釋和JavaDoc，特別是如果您發佈代碼以供其他人閱讀。其次，編寫單元測試。這將幫助您檢測行爲變化。 – 2009-12-30 09:39:22

唉唉......我是這樣一個白癡。大聲笑。我沒有真正將'row'設置爲inf.inflate（）的值。

Facepalm是的。忽視這一點。希望別人能夠找到有用的代碼。

你是對的（row = inf.inflate ...），你應該有一個NullPointerException。另外，你必須刪除第二個電話inf.inflate(R.layout.post_obj, parent, false);。否則，您將失去由convertView授予的優化...
