Question

我正在向ListFragment添加标题，但标题不会出现。我尝试添加onCreate和onStart，但我已经设置了我的适配器。我在这里找到了这个Best place to addHeaderView in ListFragment，但它无效。

@Override

     public View onCreateView(LayoutInflater inflater, ViewGroup container,
                    Bundle savedInstanceState) {
                View v = getActivity().getLayoutInflater().inflate(R.layout.header,
                        null);
                container.addView(v,0);
                rla = new RowListAdapter(getActivity().getLayoutInflater(),
                        R.layout.itemlayout, rl);
                setListAdapter(rla);
                return super.onCreateView(inflater, container, savedInstanceState);
            }

    @Override
    public void onStart() {
        super.onStart();
        getListView().setBackgroundResource(R.color.tostadoclaro);
        getListView()
                .setDivider(getResources().getDrawable(R.drawable.divider));

        getListView().setDividerHeight(4);
    }

¡¡¡SOLUTION !!!

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    View v = getActivity().getLayoutInflater().inflate(R.layout.header,
            null);
    this.getListView().addHeaderView(v);
    rla = new RowListAdapter(getActivity().getLayoutInflater(),
            R.layout.itemlayout, rl);
    setListAdapter(rla);
    super.onActivityCreated(savedInstanceState);
}
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState){// Empty. Use original.}

Answer 1

不要将视图添加到容器中。使用addHeaderView（v）。

Answer 2

完整代码（改编自here）：

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    TextView tv = new TextView(getActivity());
    tv.setText("Hello");
    getListView().addHeaderView(tv);
    setListAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1,
            new String[] { "Hello world" }));
}

@Override
public void onDestroyView() {
    setListAdapter(null);
    super.onDestroyView();
}
