内容查看未创建错误

我想通过从服务器下载图像实例化列表视图，然后在我的asynkTask类的onPostExecute（）中调用setImages（），这是我的主要活动。之后mTransaction.commit（）崩溃，我得到内容查看未创建错误

这里是我的setImages方法错误消息 “尚未创建内容查看”：

public void setImages(List<Bitmap> result) 
{ 
    log("Entered setImages()"); 

    ListViewAdapter listAdapter = new ListViewAdapter(this, R.layout.list_item,  R.id.imageView, result); 
    customListFragment = new customListFragment(); 
    customListFragment.setListAdapter(listAdapter); 

    FragmentTransaction mTransaction = mFragmentManager.beginTransaction(); 
    mTransaction.add(R.layout.activity_main, customListLineFragment); 
    mTransaction.commit(); 

}

这里是我的logcat：

这里是CustomListFragment类

public class CustomListFragment extends ListFragment { 



@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setListAdapter(new ArrayAdapter<ImageView>(getActivity(), android.R.layout.simple_list_item_1)); 

} 

@Override 
public void onAttach(Activity activity) { 
    super.onAttach(activity); 

    this.setEmptyText("...."); 

}

添加片段后设置适配器，提交。试试这个：

mTransaction.commit(); 
mFragmentManager.executePendingTransactions(); 
customListFragment.setListAdapter(listAdapter);

我仍然收到崩溃和错误消息“内容视图尚未创建”。我应该在下载数据之前添加片段视图吗？ –

你可以发布你的customListFragment onAttach和onCreateView方法吗？ – FrankenBel

我贴在上面 –
