选项菜单要求视图寻呼机中的 2 个片段如何处理??.

Question

我正在使用查看页程序片段分页机适配器，它一次加载两个片段如何处理选项菜单，一次为两个片段调用它

public class RTHomeTabFragment extends Fragment implements TabListener,OnBackButtonPressInterfaceForFragment{

Answer 1

要在单独的片段中使用单独的菜单，您只需使用

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    menu.clear();
    getActivity().getMenuInflater().inflate(R.menu.new_message_menu, menu);
}

在

片段中而不是在父活动中
