List all the installed or supported languages in a

问题:

How to get list of all the installed or supported languages that are listed under "Language and Input settings" programmatically in android. I have used Resources.getSystem().getAssets().getLocales() but it gives me only code of that language like en, en_us but I need both code and display name. I have also tried with Locale.getAvailableLocales() but it gives me repeated items and too big list.

Please tell me what is the correct way of doing this.

回答1:

getAvailableLocales() gives you all Languages,but as one/more countries can have same language,it is repeated,you can filter it using

public ArrayList<String> getAllLanguages()
{
 Locale[] locales = Locale.getAvailableLocales();
 ArrayList<String> languages=new ArrayList<String>();
 for(Locale temp : locales)
 {
   if(!languages.Contains(temp.getDisplayLanguage()))
     languages.Add(temp.getDisplayLanguage());
 }
  return languages;
}

Okay ,This will work to get Languages under input Settings

 private ArrayList<String> getInputLanguages() {
       ArrayList<String> inputlanguages=new ArrayList<String>();
       InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
       List<InputMethodInfo> ims = imm.getEnabledInputMethodList();

       for (InputMethodInfo method : ims){
           List<InputMethodSubtype> submethods = imm.getEnabledInputMethodSubtypeList(method, true);
           for (InputMethodSubtype submethod : submethods){
              if (submethod.getMode().equals("keyboard")){
                 String currentLocale = submethod.getLocale();
                 Locale locale = new Locale(localeString);
                 String currentLanguage = locale.getDisplayLanguage();   
                 inputlanguages.Add(currentLanguage );        

               }
           }
     }
 return inputlangauges;
}
