字符串文件：values / string.xml和values-pt-rBr / string.xml
setLocale(new Locale("en"));
String eng = getString(R.string.hello_world);
setLocale(new Locale("pt", "Br"));
String bra = getString(R.string.hello_world);
if (!eng.equals(bra)) {
Log.i("locale_test", "it works!");
}
public void setLocale(final Locale locale) {
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Locale.setDefault(locale);
android.content.res.Configuration conf = res.getConfiguration();
conf.locale = locale;
res.updateConfiguration(conf, dm);
}
更新：
从android开始N需要新方法
创建ContextWrapper类,并在您活动的attachBaseContext(Context)方法中使用它
public class ContextWrapper extends android.content.ContextWrapper {
public ContextWrapper(final Context base) {
super(base);
}
public static ContextWrapper wrap(Context context, Locale newLocale) {
Resources res = context.getResources();
Configuration configuration = res.getConfiguration();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
configuration.setLocale(newLocale);
LocaleList localeList = new LocaleList(newLocale);
LocaleList.setDefault(localeList);
configuration.setLocales(localeList);
} else {
configuration.setLocale(newLocale);
DisplayMetrics dm = res.getDisplayMetrics();
res.updateConfiguration(configuration, dm);
}
configuration.setLayoutDirection(newLocale);
context = context.createConfigurationContext(configuration);
return new ContextWrapper(context);
}
}
@Override protected void attachBaseContext(final Context newBase) {
String savedLocale = LocaleUtils.getSavedLocale();
if (isNotEmpty(savedLocale)) {
Locale appLocale = new Locale(savedLocale);
ContextWrapper wrapped = ContextWrapper.wrap(newBase, appLocale);
SalonyFormatter.getInstance(wrapped).refreshResources(wrapped);
super.attachBaseContext(wrapped);
} else {
super.attachBaseContext(newBase);
}
}
