Android 当区域设置更改时，ActivityReference不使用从右到左的资源

我目前正在开发一个基于代码支持3种语言的应用程序。这很好，我可以在运行时更改应用程序语言，但有一个问题让我感到困惑。不幸的是，当我想转到ActivityReference时，语言和资源仍然是英语，当我将应用程序语言更改为波斯语时，它不会使用从右到左的资源，例如布局和字符串。首选项v7有什么问题？我从应用程序中附加了一些图像，当语言为英语和波斯语时。先谢谢你

更改语言方法

private static Context updateResources(Context context, String language) {
        Locale locale = new Locale(language);
        Locale.setDefault(locale);

        Resources res = context.getResources();
        Configuration config = new Configuration(res.getConfiguration());
        if (Build.VERSION.SDK_INT >= 17) {
            config.setLocale(locale);
            context = context.createConfigurationContext(config);
        } else {
            config.locale = locale;
            res.updateConfiguration(config, res.getDisplayMetrics());
        }
        return context;
    }

活动类型参考代码

public class ActivityPreference extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_setting);

        if (savedInstanceState == null) {
            // Display the fragment as the main content.
            FragmentPreference fragmentPreference = FragmentPreference.newInstance();
            fragmentPreference.setArguments(this.getIntent().getExtras());
            this.getSupportFragmentManager().beginTransaction().replace(R.id.content, fragmentPreference).commit();
        }
    }
}

public class FragmentPreference  extends PreferenceFragmentCompat {

    public static FragmentPreference newInstance(){
        FragmentPreference fr = new FragmentPreference();
        return fr;
    }

    @Override
    public void onStart() {
        super.onStart();

        int width = ViewGroup.LayoutParams.MATCH_PARENT;
        int height = ViewGroup.LayoutParams.MATCH_PARENT;
        FragmentPreference.this.getActivity().getWindow().setLayout(width, height);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public void onCreatePreferences(Bundle bundle, String s) {
        addPreferencesFromResource(R.xml.preference);
    }
}

片段首选项代码

public class ActivityPreference extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_setting);

        if (savedInstanceState == null) {
            // Display the fragment as the main content.
            FragmentPreference fragmentPreference = FragmentPreference.newInstance();
            fragmentPreference.setArguments(this.getIntent().getExtras());
            this.getSupportFragmentManager().beginTransaction().replace(R.id.content, fragmentPreference).commit();
        }
    }
}

public class FragmentPreference  extends PreferenceFragmentCompat {

    public static FragmentPreference newInstance(){
        FragmentPreference fr = new FragmentPreference();
        return fr;
    }

    @Override
    public void onStart() {
        super.onStart();

        int width = ViewGroup.LayoutParams.MATCH_PARENT;
        int height = ViewGroup.LayoutParams.MATCH_PARENT;
        FragmentPreference.this.getActivity().getWindow().setLayout(width, height);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public void onCreatePreferences(Bundle bundle, String s) {
        addPreferencesFromResource(R.xml.preference);
    }
}

ActivityReference不支持Rtl@FarshadAsgharzadeh必须有一种方法强制ActivityReference使用rtl资源。我去年尝试过，但失败了。您必须为创建自己的自定义活动preference@FarshadAsgharzadeh它也不使用rtl字符串资源。它没有意义。您是否尝试在设置区域设置后刷新活动？
