单击选项卡时，如何保留相同的 contentView，并且仅调用在列表中应用过滤器来更改元素的方法？如果我不设置“setContent”属性，我会得到“您必须指定一种创建选项卡内容的方法”，但我不想仅为列表中的某些更改创建新视图！

这里创建和控制选项卡的类

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    super.onCreateView(inflater, container, savedInstanceState);

    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.implant_fragment, container, false);

    // Take implant listView
    _lv_imp = (ListView) view.findViewById(android.R.id.list);

    _tabHost = (TabHost) getActivity().findViewById(R.id.tabHost);

    // Tab1
    TabHost.TabSpec todoImpTab = _tabHost.newTabSpec("todo");
    // set title and icon
    todoImpTab.setIndicator("Impianti DA FARE");

// ******** Here invoke the method for change the content of listView when tab clicked ****
    filterTodoImplant();

    // Tab2
    TabHost.TabSpec allImpTab = _tabHost.newTabSpec("all");
    allImpTab.setIndicator("TUTTI gli impianti");

    listDBImplants();

    // Add tabspec to tabHost
    _tabHost.addTab(todoImpTab);
    _tabHost.addTab(allImpTab);

    return view;
}

这里是布局文件
