我可以完美地将语言更改为我的应用程序,它适用于所有活动。从来没有遇到任何问题(我的S4和我朋友的手机)。但是当我使用我的S9(Oreo 8.0)时,没有任何作用。对于某些事情,语言会发生变化,但我的应用程序的大部分内容都不会改变语言。我不明白,奥利奥的变化与我所做的不再有效?
这是我要做的改变它(例子是西班牙语):
private View.OnClickListener btnLangue3Listener = new View.OnClickListener() {
@Override
public void onClick(View v) {
langue.setBackground(ResourcesCompat.getDrawable(getResources(), R.mipmap.spanishflag, null));
langueMenu.setVisibility(View.GONE);
if (Locale.getDefault().getLanguage().equals("fr") || Locale.getDefault().getLanguage().equals("en")) {
Context context = getApplicationContext();
changeLang(context ,"es");
saveLocale("es");
restartActivity();
}
}
};
private void restartActivity() {
Intent mStartActivity = new Intent(getApplicationContext(), SplashActivity.class);
finish();
CharSequence text = getApplicationContext().getResources().getString(R.string.messageLang);
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(this, text, duration);
toast.show();
int secs = 14; // Delay in seconds
Utils.delay(secs, new Utils.DelayCallback() {
@Override
public void afterDelay() {
Intent mStartActivity = new Intent(getApplicationContext(), SplashActivity.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(getApplicationContext(), mPendingIntentId, mStartActivity, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);
}
});
}
public void loadLocale() {
String langPref = "Language";
SharedPreferences prefs = getSharedPreferences("CommonPrefs",
Activity.MODE_PRIVATE);
String language = prefs.getString(langPref, "");
changeLang(getApplicationContext(), language);
}
public void changeLang(Context context, String lang) {
if (lang.equalsIgnoreCase(""))
return;
Locale locale = new Locale(lang);
Locale.setDefault(locale);
Configuration config = getApplicationContext().getResources().getConfiguration();
config.setLocale(locale);
getApplicationContext().createConfigurationContext(config);
getApplicationContext().getResources().updateConfiguration(config, getApplicationContext().getResources().getDisplayMetrics());
}
public void saveLocale(String lang) {
String langPref = "Language";
SharedPreferences prefs = getSharedPreferences("CommonPrefs",
Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString(langPref, lang);
editor.commit();
}
tl; dr:我将语言环境更改为“es”,重新启动活动和应用程序(如果我没有重新启动应用程序,则无法运行)并将其保存在共享首选项中。活动打开后,我检索共享首选项并将其用作以下语言环境: 首先我调用loadLocale();然后:
public void loadLocale() {
String langPref = "Language";
SharedPreferences prefs = getSharedPreferences("CommonPrefs",
Activity.MODE_PRIVATE);
String language = prefs.getString(langPref, "");
changeLang(language);
}
public void changeLang(String lang) {
if (lang.equalsIgnoreCase(""))
return;
Locale myLocale = new Locale(lang);
saveLocale(lang);
Locale.setDefault(myLocale);
Configuration config = getApplicationContext().getResources().getConfiguration();
config.setLocale(myLocale);
this.createConfigurationContext(config);
this.getResources().updateConfiguration(config, getApplicationContext().getResources().getDisplayMetrics());
}
public void saveLocale(String lang) {
String langPref = "Language";
SharedPreferences prefs = getSharedPreferences("CommonPrefs",
Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString(langPref, lang);
editor.commit();
}
我做错了什么?有更简单或更好的方法吗?我到处搜索,没有任何效果......
