如何在选项卡中添加片段

Question

public class TabFragment扩展了Fragment {

private TabHost mTabHost;
View rootView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    rootView = inflater.inflate(R.layout.tabinterview, container, false);
    mTabHost = (TabHost) rootView.findViewById(R.id.tabhost);
    mTabHost.setup();
    TabHost.TabSpec spec = mTabHost.newTabSpec("tag");
    spec.setIndicator("Android");
    spec.setContent(new TabHost.TabContentFactory() {

        @Override
        public View createTabContent(String tag) {
            // TODO Auto-generated method stub
            return (new QuestionFragment().getView());
        }
    });
    mTabHost.addTab(spec);

    return rootView;
}

}

在上面的代码我创建了选项卡，在内部选项卡中我必须添加相应的片段 我有结帐选项卡显示在片段，但当我尝试添加选项卡问题片段的设置内容时，我收到以下错误

请帮我在标签中添加片段或建议我任何其他逻辑

我认为你正在寻找像这样的tabbar概念。

为此我可以使用以下链接。
