android 自定义locale,android – 以编程方式设置Locale

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

configuration.setLocale(locale);

考虑到此方法的minSkdVersion是API 17.

完整示例代码：

@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 Activity,以便在每次创建Activity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(语言环境)设置语言环境时将语言保存到SharedPreferences
