Load all languages in Android

I have several language files in Android application: value/strings.xml, value-en/strings.xml, ...etc It is possible to load the content of this files in some arrays or something. For example, I would like to load default text strings and english strings in 2 different arrays at run time.

Thanks

Create a method like this:

Resources getResourcesByLocale( Context context, String localeName ) {
    Resource res = context.getResources();
    Configuration conf = new Configuration(res.getConfiguration());
    conf.locale = new Locale(localeName);
    return new Resources(res.getAssets(), res.getDisplayMetrics(), conf);
}

Than you can get resources for any locale you've defined, for example:

Resources res_en = getResourcesByLocale(context, "en");
Resources res_de = getResourcesByLocale(context, "de");
Resources res_fr = getResourcesByLocale(context, "fr");

String some_name_en = res_en.getString(R.string.some_name);
String some_name_fr = res_fr.getString(R.string.some_name);
// etc...

Moreover, you do not need to take care about exceptions if you did not define string for some locale, because anyway default (from res/values/*) will be loaded instead.

Actually the situation is like that. Imagine I have this scenario: some chinese open the application. He has the mobile phone set with ch locale. The application default is xx as language, meaning I have 2 language files values/strings.xml (spanish for eg as default) and another language values-en/strings.xml for english. The default will make no sense for him, so english will be the most appropiate for his understanding, even if he does not understand it very good. So at the app start I open language settings (android language settings), where any selection will set the app in spanish unless he select english. I am forcing him to change the phone locale in english basically, just to use my app. Overall the concept of android is wrong, because i need to be able to see an application in any language I want without changing device language.

What I have done: - I created in values folder one more string_xx.xml file. Now, for a translation string name = "txtTranslation" I have in string_xx file "en_txtTranslation" key. R.java loads them all and in my app, based on a global var selectedLanguage = xx, I attach the write string using this code: 

public String translate(String text)
{
      String appLanguage = UtilsCentral.getUserLanguage(getApplicationContext());
      if (appLanguage != "")
      {
          return getString(getResources().getIdentifier(appLanguage + "_" + text, "string", this.getPackageName()));  
      }
      else 
      {
          return getString(getResources().getIdentifier(text, "string", this.getPackageName()));
      }
}

Indeed, at activity on create i need to set all views with .text = tarnslate("txtTranslation")

Note: UtilsCentral.getUserLanguage(getApplicationContext()) returns app language (user selection)

Conclusion, there is more unuseful work, but lets me do what i need, and what i believe is normal.
