下面是我所做获得可用的输入语言：

Here's what I did to get the available input languages:

    private void printInputLanguages() {
       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();
                 Log.i(TAG, "Available input method locale: " + currentLocale);
              }
           }
    }
}
