未创建片段视图的 Android ListView

Question

我在片段中使用 ListView，并且按照 Android 的说明设置了所有必要的要求，下面是我的 XML 列表代码

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@id/android:list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
        android:background="#253453">
    </ListView>

</LinearLayout>

在我的代码中

   @Override
public View onCreateView(LayoutInflater inflater,
        @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    View android = inflater.inflate(R.layout.pending_frag, container, false);
    context = getActivity().getApplicationContext();
    //ListView list = (ListView)android.findViewById(R.id.list);
    ListView list = getListView();

      trackItems = new ArrayList<TrackItem>();
      listAdapter = new TrackOrderListAdapter(getActivity(), trackItems);
      list.setAdapter(listAdapter); }

但是，我仍然收到此错误

Answer 1

 @Override
public View onCreateView(LayoutInflater inflater,
        @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    return inflater.inflate(R.layout.pending_frag, container, false);

}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onViewCreated(view, savedInstanceState);
    context = getActivity().getApplicationContext();
    //ListView list = (ListView)android.findViewById(R.id.list);
    ListView list = getListView();

    trackItems = new ArrayList<TrackItem>();
    listAdapter = new TrackOrderListAdapter(getActivity(), trackItems);
    list.setAdapter(listAdapter); 
}

在创建视图之前，您无法真正操作视图。
