sch*_*rer 34 android locale localization android-resources
使用案例:记录显示给用户的错误消息.
但是,您不希望日志中的消息依赖于用户设备的区域设置.另一方面,您不希望仅为您的(技术)日志记录更改用户设备的区域设置.这可以实现吗?我在stackoverflow上找到了几个可能的解决方案:
但是,它们都会导致更改设备的区域设置(直到下一次配置更改).
无论如何,我目前的解决方法是这样的:
public String getStringInDefaultLocale(int resId) {
Resources currentResources = getResources();
AssetManager assets = currentResources.getAssets();
DisplayMetrics metrics = currentResources.getDisplayMetrics();
Configuration config = new Configuration(
currentResources.getConfiguration());
config.locale = DEFAULT_LOCALE;
/*
* Note: This (temporiarily) changes the devices locale! TODO find a
* better way to get the string in the specific locale
*/
Resources defaultLocaleResources = new Resources(assets, metrics,
config);
String string = defaultLocaleResources.getString(resId);
// Restore device-specific locale
new Resources(assets, metrics, currentResources.getConfiguration());
return string;
}

说实话,我根本不喜欢这种方法.它并不高效 - 考虑并发性和所有这些 - 它可能导致"错误"区域设置中的某些视图.
所以 - 任何想法?也许这可以使用ResourceBundle实现,就像在标准Java中一样?

你可以使用它 API +17
@NonNull
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
public static String getStringByLocal(Activity context, int id, String locale) {
Configuration configuration = new Configuration(context.getResources().getConfiguration());
configuration.setLocale(new Locale(locale));
return context.createConfigurationContext(configuration).getResources().getString(id);
}

更新(1):如何支持旧版本.
@NonNull
public static String getStringByLocal(Activity context, int resId, String locale) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1)
return getStringByLocalPlus17(context, resId, locale);
else
return getStringByLocalBefore17(context, resId, locale);
}

更新(2): 查看这篇文章
感谢 @Khaled Lela 的回答,我做了一个 Kotlin 扩展:
fun Context.getStringByLocale(@StringRes stringRes: Int, locale: Locale, vararg formatArgs: Any): String {
val configuration = Configuration(resources.configuration)
configuration.setLocale(locale)
return createConfigurationContext(configuration).resources.getString(stringRes, *formatArgs)
}

我直接在 或相关类中使用Activity,Fragment只需Context简单地调用:
getStringByLocale(R.string.my_text, Locale.UK)或带参数:
getStringByLocale(R.string.my_other_text, Locale.RU, arg1, arg2, arg3)
