Question

我的应用程序有一个滑动的抽屉菜单，我需要在滑动菜单的一个片段中加载preferenceFragment。我创建了一个代码，其中preferenceFragment被加载到片段中，但当我关闭抽屉时，prefrenceFragment不会消失我只能通过按下后退按钮来关闭它。我的完整代码和应用程序图像显示在下面。请帮帮我吗？

设置片段

public class Settings_fragment extends Fragment
{
public Settings_fragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
{
    View rootView = inflater.inflate(R.layout.fragment_about, container, false); 

    getActivity().getFragmentManager().beginTransaction().replace(android.R.id.content, new MyPreferenceFragment()).commit();
    return rootView;
}
public static class MyPreferenceFragment extends PreferenceFragment
{
        @Override
        public void onCreate(final Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.preference_layout);
        }
}
}

NavigationDrawer

我有同样的问题，我通过更换解决了的 android.R.id.content 至的 R.id.container 即可。

Answer 3

你正在取代SettingsFragment中的PreferenceFragment onCreateView为什么？根据您的代码，您将使用PreferenceFragment替换SettingsFragment，它是静态的，而不是销毁或删除，避免代码中的静态成员函数，类和变量，因为它们在代码中的任何位置都可以全局使用。浏览您的代码并编辑您的问题
