Question

I am creating a translator app in which user need to choose the target language if suppose he choose French from the spinner then value for the FRENCH should be 'fr' so i can pass that value in url. I have created a spinner and assigned languages from array adapter but I want to use it's short form like for French the value should be fr how can I achieve that?

"French","fr" "Arabic", "ar" "English", "en"

my app shows the language list KEY and app crahes when translate button is pressed here is my code, what next

Spinner spinner = findViewById(R.id.spinner);

    Map<String, String> flanguages = new HashMap<String, String>();
    flanguages.put("Arabic", "ar");
    flanguages.put("English", "en");
    flanguages.put("French", "fr");
    flanguages.put("Hausa", "ha");
    flanguages.put("Igbo", "ig");
    flanguages.put("Yoruba", "yo");

    List<String> list = new ArrayList<String>(flanguages.keySet());


    ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, list);
    arrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(arrayAdapter);

Answer 1

Easiest way to do is to create a LanguageItem Class.

class LanguageItem{
    String language;
    String isoCode;

    override String toString(){
      return language;
   }
}

Use this class to add your language and its iso code. Put it in ArrayList and show it in spinner.

ArrayAdapter<LanguageItem> adapter = new ArrayAdpter(this, android.R.layout.simple_spinner_item, arraylist)

Now onItemSelected you can easily get selected LanguageItem with the position.
