Android - 为什么我不能向 ListFragment 的 ListView 添加页脚视图？

Question

我之前在 ListActivity 中运行此代码没有问题，现在我正在重构以使用 ListFragment 并且代码编译但我看不到任何按钮（页脚）

代码：

@Override
public void onActivityCreated(Bundle savedInstanceState)
{
    super.onActivityCreated(savedInstanceState);

    log("+ ON ACTIVITY CREATED +");

    listView = getListView();

    // Retrieve routines ArrayList from JSON
    routineList = FitnessApp.routineList;   

    routineList.add(new Routine("test routine"));

    adapter = new GeneralTemplateAdapter(routineList, getActivity().getLayoutInflater());

    listView.setAdapter(adapter);

    // Creating bottom button as a footer view
    Button bAddNew = (Button) getActivity().getLayoutInflater().inflate(R.layout.add_new_button, null);
    bAddNew.setText("Add Routine");

    listView = getListView();   // Get reference to ListActivities ListView
    listView.addFooterView(bAddNew);
}

有什么想法吗？

干杯

啊，我忘记了在添加适配器之前必须声明页眉和页脚的简单事实
