Java 内容视图未创建错误

我试图通过从服务器下载图像来实例化列表视图，然后在asynkTask类的onPostExecute中调用主活动中的setImages。在mTransaction.commit崩溃后，我收到了错误消息“内容视图尚未创建”

以下是我的setImages方法：

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();

}

下面是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("....");

}

在添加片段和提交后设置适配器。 试试这个：

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

我仍然得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？你能发布你的customListFragment-onAttach和onCreateView方法吗？

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