Question

在我的Android应用程序中，我想更改语言表单片段。我的应用程序包含MainActivity.java。此活动包含导航抽屉和片段。当我从片段中更改我的语言环境时，语言会在导航抽屉中的每个位置都更改。我正在使用代码

private String setLocal() {
    Locale locale;
    Resources res = getResources();
    DisplayMetrics dm = res.getDisplayMetrics();
    Configuration conf = res.getConfiguration();
    prefs = getActivity().getSharedPreferences("Language", 0);
    String restoredText = prefs.getString("language", "");
    if (restoredText.equalsIgnoreCase("fr_FR"))
        locale = new Locale("fr");

    else
        locale = new Locale("en");
    Locale.setDefault(locale);
    conf = new Configuration();
    res.updateConfiguration(conf, dm);

    return restoredText;
}

当我选择英语时，我得到以下结果

改变语言后我得到了这个

这是来自values-fr目录的字符串文件

 <string-array name="nav_drawer_titles">
    <item>Accueil</item>
    <item>Profil</item>
    <item>courses</item>
    <item>Tarification</item>
    <item>Configuration</item>
    <item>Envoyez à un ami</item>
    <item>Facture</item>
    <item>Position du Chaufeur</item>
    <item>Aide</item>
    <item>Déconnexion</item>
</string-array>

此处来自值文件夹

 <!-- Nav Drawer Menu Items -->
<string-array name="nav_drawer_titles">
    <item>Home</item>
    <item>Profile</item>
    <item>Ride Log</item>
    <item>Invoice</item>
    <item>Track Chauffeur</item>
    <item>Language</item>
    <item>Refer To Friend</item>
    <item>Help</item>
    <item>Sign Out</item>
</string-array>

我的navigationdrawerfragnet是

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    title = getResources().getStringArray(R.array.nav_drawer_titles);

    images = getResources().getStringArray(R.array.nav_drawer_icons);


    mDrawerListView = (ListView) inflater.inflate(
            R.layout.fragment_navigation_drawer, container, false);


    mDrawerListView
            .setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
                    selectItem(position);
                }
            });
    selectedposition = new int[] { mCurrentSelectedPosition };
    drawerAdapter = new CustomDrawerAdapter(getActivity(), title, images,
            selectedposition);

    mDrawerListView.setItemChecked(mCurrentSelectedPosition, true);
    mDrawerListView.setAdapter(drawerAdapter);
    return mDrawerListView;
}

Im MainActivity.java

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    super.onPrepareOptionsMenu(menu);
    invalidateOptionsMenu();
    setLocal();
    return super.onPrepareOptionsMenu(menu);
}
@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    setLocal();
    invalidateOptionsMenu();
}

Answer 1

您应该在setContentView(int resId)之前在抽屉活动中设置您的区域设置。

同样在onResume()方法中，您可以使用API_LEVEL >= 11重新调整您的活动致电super.recreate()以及11以下，您可以设置onCreate(null)。

Answer 2

检查this

title = getResources().getStringArray(R.array.nav_drawer_titles);

images = getResources().getStringArray(R.array.nav_drawer_icons);

   mDrawerListView
        .setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                selectItem(position);
            }
        });
selectedposition = new int[] { mCurrentSelectedPosition };
drawerAdapter = new CustomDrawerAdapter(getActivity(), title, images,
        selectedposition);

mDrawerListView.setItemChecked(mCurrentSelectedPosition, true);
mDrawerListView.setAdapter(drawerAdapter);

您需要在setLocal方法上按下该行以使抽屉列表无效
