protected void setLanguage(String language){
    mylocale=new Locale(language);
    Resources resources=getResources();
    DisplayMetrics dm=resources.getDisplayMetrics();
    Configuration conf= resources.getConfiguration();
    conf.locale=mylocale;
    resources.updateConfiguration(conf,dm);
    //Intent refreshIntent=new Intent(LanguageListActivity.this,MainActivity.class);
    finish();
    //startActivity(refreshIntent);
}

我想保存上次选择的语言-为此您需要使用SharedPreferences

有关SharedPreferences的参考：共享首选项

要存储在SharedPreferences中：

SharedPreferences sharedPref = getActivity().getPreferences(MY_PREFS_NAME,Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("lang", language);
editor.commit();

Context context = getActivity();
SharedPreferences sharedPref = context.getSharedPreferences(
       MY_PREFS_NAME, Context.MODE_PRIVATE);
String language = sharedPref.getString("lang", null);
