未创建具有片段视图的Android列表视图

Question

我在一个片段中使用ListView，我已经按照Android的指示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，我仍然得到这个错误

08-20 23:26:26.053:E/AndroidRuntime（30334）：致命异常：main 08-20 23:206:26.053：E/Android Runtime“30334”：进程：com.deliveryscience.track，PID:3034 08-20 23:26:26.053:E/AndroidRuntime（30334）:java.lang.IllegalStateException：内容视图尚未创建08-20 23:20 26.053:E/android Runtime：E/android运行时（30334）：位于com.deliveryscience.track.PendingActivity.onCreateView（PendingAction.java:51）08-20 23:26:26.053:E/AndroidRuntime（30334）：位于android.support.v4.app.Fragment.performCreateView（Fragment.java:1504）08-20 23时26分053:E/AndroidRuntime 34）：在android.support.v4.app.FragmentManagerImpl.moveToState（FragmentManager.java:1121）08-20 23:26:26.053:E/AndroidRuntime（30334）：位于android.support.v 4.app.BackStackRecord.run（BackStack Record.java:682）08-20 23时26分053:E/AndroidRuntime运行时间（30334）：在android.support.v4.app.FragmentManagerImpl.executePendingTransactions（FragmentManager.java:482）08-20 23:26:26.053:E/AndroidRuntime（30334）：位于android.support.v 4.app.FragmentStatePagerAdapter.finishUpdate（Fragment StatePager适配器.java:163）08-20 23时26分26秒053:E/AndroidRuntime oidRuntime（30334）：在android.support.v4.view.ViewPager.populate（ViewPager.java:919）08-20 23:26:26.053:E/AndroidRuntime（30334）：在android.support.v4.view.ViewPager.onMeasure（ViewPager.java:1441）

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，您无法真正操纵视图。
