以编程方式设置区域设置

时间:2011-02-13 17:51:34

标签: android locale user-defined

我的应用支持3种(很快就有4种)语言。由于几个语言环境非常相似,我想让用户选择在我的应用程序中更改语言环境,例如意大利人可能更喜欢西班牙语而不是英语。

用户是否有办法在可用于应用程序的区域设置中进行选择,然后更改使用的区域设置?我不认为为每个Activity设置区域设置是一个问题,因为它是在基类中执行的简单任务。

希望这个帮助(在onResume上):

Locale locale = new Locale("ru");
Locale.setDefault(locale);
Configuration config = getBaseContext().getResources().getConfiguration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
      getBaseContext().getResources().getDisplayMetrics());

对于仍在寻找此答案的人,由于configuration.locale已弃用,您现在可以使用API​​ 24:

configuration.setLocale(locale);

请注意此方法的minSkdVersion是API 17。

完整的示例代码:

@SuppressWarnings("deprecation")
private void setLocale(Locale locale){
    SharedPrefUtils.saveLocale(locale); // optional - Helper method to save the selected language to SharedPreferences in case you might need to attach to activity context (you will need to code this)
    Resources resources = getResources();
    Configuration configuration = resources.getConfiguration();
    DisplayMetrics displayMetrics = resources.getDisplayMetrics();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1){
        configuration.setLocale(locale);
    } else{
        configuration.locale=locale;
    }
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
        getApplicationContext().createConfigurationContext(configuration);
    } else {
        resources.updateConfiguration(configuration,displayMetrics);
    }
}

不要忘记,如果您使用正在运行的Activity更改语言环境,则需要重新启动它才能使更改生效。

从@ CookieMonster的帖子开始,您可能无法在较高的API版本中保持区域设置更改。如果是这样,请将以下代码添加到Base活动中,以便在每次创建活动时更新上下文区域设置:

@Override
protected void attachBaseContext(Context base) {
     super.attachBaseContext(updateBaseContextLocale(base));
}

private Context updateBaseContextLocale(Context context) {
    String language = SharedPrefUtils.getSavedLanguage(); // Helper method to get saved language from SharedPreferences
    Locale locale = new Locale(language);
    Locale.setDefault(locale);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return updateResourcesLocale(context, locale);
    }

    return updateResourcesLocaleLegacy(context, locale);
}

@TargetApi(Build.VERSION_CODES.N)
private Context updateResourcesLocale(Context context, Locale locale) {
    Configuration configuration = context.getResources().getConfiguration();
    configuration.setLocale(locale);
    return context.createConfigurationContext(configuration);
}

@SuppressWarnings("deprecation")
private Context updateResourcesLocaleLegacy(Context context, Locale locale) {
    Resources resources = context.getResources();
    Configuration configuration = resources.getConfiguration();
    configuration.locale = locale;
    resources.updateConfiguration(configuration, resources.getDisplayMetrics());
    return context;
}

如果您使用此功能,请不要忘记在使用setLocate(locale)

设置区域设置时将语言保存到SharedPreferences

答案 2 :(得分:14)

@SuppressWarnings("deprecation")
public static void forceLocale(Context context, String localeCode) {
    String localeCodeLowerCase = localeCode.toLowerCase();

    Resources resources = context.getApplicationContext().getResources();
    Configuration overrideConfiguration = resources.getConfiguration();
    Locale overrideLocale = new Locale(localeCodeLowerCase);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        overrideConfiguration.setLocale(overrideLocale);
    } else {
        overrideConfiguration.locale = overrideLocale;
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        context.getApplicationContext().createConfigurationContext(overrideConfiguration);
    } else {
        resources.updateConfiguration(overrideConfiguration, null);
    }
}

只需使用此辅助方法强制使用特定区域设置。

答案 3 :(得分:13)

我在使用设备以编程方式设置区域设置时出现问题 Android OS N及更高版。 对我来说,解决方案是在我的基本活动中编写此代码:

(如果您没有基本活动,那么您应该在所有活动中进行这些更改)

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(updateBaseContextLocale(base));
}

private Context updateBaseContextLocale(Context context) {
    String language = SharedPref.getInstance().getSavedLanguage();
    Locale locale = new Locale(language);
    Locale.setDefault(locale);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        return updateResourcesLocale(context, locale);
    }

    return updateResourcesLocaleLegacy(context, locale);
}

@TargetApi(Build.VERSION_CODES.N)
private Context updateResourcesLocale(Context context, Locale locale) {
    Configuration configuration = context.getResources().getConfiguration();
    configuration.setLocale(locale);
    return context.createConfigurationContext(configuration);
}

@SuppressWarnings("deprecation")
private Context updateResourcesLocaleLegacy(Context context, Locale locale) {
    Resources resources = context.getResources();
    Configuration configuration = resources.getConfiguration();
    configuration.locale = locale;
    resources.updateConfiguration(configuration, resources.getDisplayMetrics());
    return context;
}

请注意,这里只能调用

createConfigurationContext(configuration)

您还需要获取此方法返回的上下文,然后在attachBaseContext方法中设置此上下文。

由于目前解决此问题的方法尚未完成,我尝试提供完整解决方案的说明。如果遗漏或可以做得更好,请评论。

一般信息

首先,存在一些想要解决问题的库,但它们似乎都已过时或缺少某些功能:

此外,我认为编写库可能不是解决此问题的好/简单方法,因为没有太多工作要做,而且必须要做的是改变现有代码而不是使用完全解耦的东西。 因此,我编写了以下应该完成的说明。

我的解决方案主要基于https://github.com/gunhansancar/ChangeLanguageExample(已经由localhost链接)。这是我发现的最佳代码。一些评论:

  • 根据需要,它提供了不同的实现来更改Android N(及以上)及以下
  • 的区域设置
  • 它使用每个Activity中的方法updateViews()在更改区域设置后使用通常的getString(id)手动更新所有字符串,这在下面显示的方法中是不必要的
  • 它仅支持语言而非完整的语言环境(也包括区域(国家/地区)和变体代码)

我改变了一点,将持久保存所选语言环境的部分解耦(如下所示,人们可能想单独进行此操作)。

解决方案

解决方案包括以下两个步骤:

  • 永久更改应用程序使用的区域设置
  • 使应用程序使用自定义区域设置,而无需重新启动

第1步:更改区域设置

根据gunhansancar's LocaleHelper

使用课程LocaleHelper
  • 使用可用语言在ListPreference中添加PreferenceFragment(必须在以后添加语言时进行维护)
import android.annotation.TargetApi;
import android.content.Context;
import android.content.SharedPreferences;
import android.content.res.Configuration;
import android.content.res.Resources;
import android.os.Build;
import android.preference.PreferenceManager;

import java.util.Locale;

import mypackage.SettingsFragment;

/**
 * Manages setting of the app's locale.
 */
public class LocaleHelper {

    public static Context onAttach(Context context) {
        String locale = getPersistedLocale(context);
        return setLocale(context, locale);
    }

    public static String getPersistedLocale(Context context) {
        SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
        return preferences.getString(SettingsFragment.KEY_PREF_LANGUAGE, "");
    }

    /**
     * Set the app's locale to the one specified by the given String.
     *
     * @param context
     * @param localeSpec a locale specification as used for Android resources (NOTE: does not
     *                   support country and variant codes so far); the special string "system" sets
     *                   the locale to the locale specified in system settings
     * @return
     */
    public static Context setLocale(Context context, String localeSpec) {
        Locale locale;
        if (localeSpec.equals("system")) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                locale = Resources.getSystem().getConfiguration().getLocales().get(0);
            } else {
                //noinspection deprecation
                locale = Resources.getSystem().getConfiguration().locale;
            }
        } else {
            locale = new Locale(localeSpec);
        }
        Locale.setDefault(locale);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            return updateResources(context, locale);
        } else {
            return updateResourcesLegacy(context, locale);
        }
    }

    @TargetApi(Build.VERSION_CODES.N)
    private static Context updateResources(Context context, Locale locale) {
        Configuration configuration = context.getResources().getConfiguration();
        configuration.setLocale(locale);
        configuration.setLayoutDirection(locale);

        return context.createConfigurationContext(configuration);
    }

    @SuppressWarnings("deprecation")
    private static Context updateResourcesLegacy(Context context, Locale locale) {
        Resources resources = context.getResources();

        Configuration configuration = resources.getConfiguration();
        configuration.locale = locale;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            configuration.setLayoutDirection(locale);
        }

        resources.updateConfiguration(configuration, resources.getDisplayMetrics());

        return context;
    }
}

创建SettingsFragment,如下所示:

import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceFragment;
import android.preference.PreferenceManager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import mypackage.LocaleHelper;
import mypackage.R;

/**
 * Fragment containing the app's main settings.
 */
public class SettingsFragment extends PreferenceFragment implements SharedPreferences.OnSharedPreferenceChangeListener {
    public static final String KEY_PREF_LANGUAGE = "pref_key_language";

    public SettingsFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.preferences);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_settings, container, false);
        return view;
    }

    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
        switch (key) {
            case KEY_PREF_LANGUAGE:
                LocaleHelper.setLocale(getContext(), PreferenceManager.getDefaultSharedPreferences(getContext()).getString(key, ""));
                getActivity().recreate(); // necessary here because this Activity is currently running and thus a recreate() in onResume() would be too late
                break;
        }
    }

    @Override
    public void onResume() {
        super.onResume();
        // documentation requires that a reference to the listener is kept as long as it may be called, which is the case as it can only be called from this Fragment
        getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
    }

    @Override
    public void onPause() {
        super.onPause();
        getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
    }
}

使用以下方式(list of locale codes)创建一个资源locales.xml列出包含可用翻译的所有区域设置:

<!-- Lists available locales used for setting the locale manually.
     For now only language codes (locale codes without country and variant) are supported.
     Has to be in sync with "settings_language_values" in strings.xml (the entries must correspond).
  -->
<resources>
    <string name="system_locale" translatable="false">system</string>
    <string name="default_locale" translatable="false"></string>
    <string-array name="locales">
        <item>@string/system_locale</item> <!-- system setting -->
        <item>@string/default_locale</item> <!-- default locale -->
        <item>de</item>
    </string-array>
</resources>

PreferenceScreen中,您可以使用以下部分让用户选择可用的语言:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory
        android:title="@string/preferences_category_general">
        <ListPreference
            android:key="pref_key_language"
            android:title="@string/preferences_language"
            android:dialogTitle="@string/preferences_language"
            android:entries="@array/settings_language_values"
            android:entryValues="@array/locales"
            android:defaultValue="@string/system_locale"
            android:summary="%s">
        </ListPreference>
    </PreferenceCategory>
</PreferenceScreen>

使用strings.xml中的以下字符串:

<string name="preferences_category_general">General</string>
<string name="preferences_language">Language</string>
<!-- NOTE: Has to correspond to array "locales" in locales.xml (elements in same orderwith) -->
<string-array name="settings_language_values">
    <item>Default (System setting)</item>
    <item>English</item>
    <item>German</item>
</string-array>

第2步:使应用程序使用自定义区域设置

现在设置每个Activity以使用自定义区域设置。完成此操作的最简单方法是使用以下代码为所有活动创建公共基类(重要代码位于attachBaseContext(Context base)onResume()中):

import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;

import mypackage.LocaleHelper;
import mypackage.R;

/**
 * {@link AppCompatActivity} with main menu in the action bar. Automatically recreates
 * the activity when the locale has changed.
 */
public class MenuAppCompatActivity extends AppCompatActivity {
    private String initialLocale;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        initialLocale = LocaleHelper.getPersistedLocale(this);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.menu_settings:
                Intent intent = new Intent(this, SettingsActivity.class);
                startActivity(intent);
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(LocaleHelper.onAttach(base));
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (initialLocale != null && !initialLocale.equals(LocaleHelper.getPersistedLocale(this))) {
            recreate();
        }
    }
}

它做的是

  • 覆盖attachBaseContext(Context base)以使用先前使用LocaleHelper
  • 保留的区域设置
  • 检测区域设置的更改并重新创建活动以更新其字符串

关于此解决方案的说明

  • 重新创建活动不会更新ActionBar的标题(如此处所示:https://github.com/gunhansancar/ChangeLanguageExample/issues/1)。

    • 只需在每项活动的setTitle(R.string.mytitle)方法中设置onCreate()即可实现。
  • 它允许用户选择系统默认语言环境,以及应用程序的默认语言环境(可以命名,在本例中为“英语”)。

  • 到目前为止,仅支持语言代码,无区域(国家/地区)和变体代码(例如fr-rCA)。要支持完整的语言环境规范,可以使用类似于Android-Languages library中的解析器(支持区域但不包含变体代码)。

    • 如果有人找到或编写了一个好的解析器,请添加注释,以便我可以将其包含在解决方案中。

使用以下方法添加辅助类:

public class LanguageHelper {
    public static final void setAppLocale(String language, Activity activity) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            Resources resources = activity.getResources();
            Configuration configuration = resources.getConfiguration();
            configuration.setLocale(new Locale(language));
            activity.getApplicationContext().createConfigurationContext(configuration);
        } else {
            Locale locale = new Locale(language);
            Locale.setDefault(locale);
            Configuration config = activity.getResources().getConfiguration();
            config.locale = locale;
            activity.getResources().updateConfiguration(config,
                    activity.getResources().getDisplayMetrics());
        }

    }
}

并在您的启动活动中调用它,例如MainActivity.java

public void onCreate(Bundle savedInstanceState) {
    ...
    LanguageHelper.setAppLocale("fa", this);
    ...
}

简单易用

Locale locale = new Locale("en", "US");
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = locale;
res.updateConfiguration(conf, dm);

其中“en”是语言代码,“US”是国家/地区代码。

在您的每个活动中添加此代码以解决此问题:

Configuration.setLocale

答案 11 :(得分:0)

对API16到API28有效 只需将此方法放在以下位置:

    Context newContext = context;

        Locale locale = new Locale(languageCode);
        Locale.setDefault(locale);

        Resources resources = context.getResources();
        Configuration config = new Configuration(resources.getConfiguration());

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {

        config.setLocale(locale);
                newContext = context.createConfigurationContext(config);

        } else {

        config.locale = locale;
                resources.updateConfiguration(config, resources.getDisplayMetrics());
        }

    return newContext;
}

使用以下代码在所有活动中插入此代码:

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(localeUpdateResources(base, "<-- language code -->"));
    }

或在需要新上下文的地方在片段,适配器等上调用localeUpdateResources。

截至2020年,语言管理变得轻松!您所要做的就是:

  1. 致电Activity.applyOverrideConfiguration
  2. 然后致电Locale.setDefault

您必须从活动构造器调用它们,因为您只能调用一次applyOverrideConfiguration,并且系统很早就调用它。

并注意应用程序捆绑包,当使用应用程序捆绑包时,Google会自动按语言资源拆分APK。查看新的API和解决方法here


我创建了一个帮助器类来帮助您。在我的实现中,G.app是应用程序上下文。另外,我需要从应用程序上下文访问资源,因此我使用Res类,该类是可选的,但我也提供了其代码。

用法

public BaseActivity(){
    LanguageUtility.init(this);
}

public void changeLanguage(Local local){
    // you must recreat your activity after you call this
    LanguageUtillity.setDefaultLanguage(local, this);
}

源代码

public class LanguageUtility {

    private static Configuration configuration;

    public static void setDefaultLanguage(Locale locale, Context context) {
        Locale.setDefault(locale);

        context.getSharedPreferences("LocaleSettings", Context.MODE_PRIVATE)
                .edit()
                .putString("language", locale.getLanguage())
                .putString("country", locale.getCountry())
                .putString("variant", locale.getVariant())
                .apply();

        configuration = createConfiguration(context);
        Res.updateContext();
    }

    /**
     * Used to update your app context in case you cache it.
     */
    public static Context createConfigurationContext(Context context) {
        return context.createConfigurationContext(getConfiguration(context));
    }

    public static void init(Activity activity) {
        activity.applyOverrideConfiguration(LanguageUtility.getConfiguration(G.app));
        // you can't access sharedPrefferences from activity constructor 
        // with activity context, so I used the app context.
        Locale.setDefault(getLocale(G.app));
    }

    @NotNull
    private static Configuration getConfiguration(Context context) {
        if (configuration == null) {
            configuration = createConfiguration(context);
        }
        return configuration;
    }

    @NotNull
    private static Configuration createConfiguration(Context context) {
        Locale locale = getLocale(context);
        Configuration configuration = new Configuration();
        configuration.setLocale(locale);
        LanguageUtility.configuration = configuration;
        return configuration;
    }

        Locale aDefault = Locale.getDefault();
        SharedPreferences preferences =
                context.getSharedPreferences("LocaleSettings", Context.MODE_PRIVATE);
        String language = preferences.getString("language", aDefault.getLanguage());
        String country = preferences.getString("country", aDefault.getCountry());
        String variant = preferences.getString("variant", aDefault.getVariant());

将此代码放入您的活动

 if (id==R.id.uz)
    {
        LocaleHelper.setLocale(MainActivity.this, mLanguageCode);

        //It is required to recreate the activity to reflect the change in UI.
        recreate();
        return true;
    }
    if (id == R.id.ru) {

        LocaleHelper.setLocale(MainActivity.this, mLanguageCode);

        //It is required to recreate the activity to reflect the change in UI.
        recreate();
    }
