Best practice to implement key-value pair in android Spinner

Question

I want to implement an android spinner with key value .

en:english jp:japanese

And when user select and item I want to save key to database . And also on next load I want spinner to select a particulate spinner position.

Can any one please tell me what is the best way to implement this.

I have tried following but doesn't met my requirement https://gist.github.com/granoeste/2786663 Set Key and Value in spinner

Write now I am using LinkedHashMapAdapter. But issue is that here I need to store position in DB or local shared preference . I don't think this a better solution

Current Implementation

LinkedHashMap localeList = new LinkedHashMap<>();

        for (Map.Entry<String, String> val : map.entrySet()) {
            int resourceId = getResources().getIdentifier(val.getValue(), "string", getPackageName());
            localeList.put(val.getKey(), getResources().getString(resourceId));

        }
        LinkedHashMapAdapter<String, String> arrayAdapter = new LinkedHashMapAdapter<>(this, R.layout.spinner_layout, localeList);
        arrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        mLocale.setAdapter(arrayAdapter);
        String localPosSelected = PreferencesHelper.getSharedPreferenceString(this, Constants.PREF_LOCALE_POS_KEY);
        if(localPosSelected!=null){
            mLocale.setSelection(Integer.parseInt(localPosSelected));
        }

Also is there an option to selected item of Spinner by value

Answer 1

setup Spinner:

        spLang = (Spinner)view.findViewById( R.id.spLang );
        spLang.setOnItemSelectedListener( this );
        ArrayList<String> sp_Lang = new ArrayList<String>();
        sp_Lang.add("english");
        sp_Lang.add("french");
        ArrayAdapter<String> spinnerAdapter = new ArrayAdapter<String>(this,
                    android.R.layout.simple_spinner_item, sp_Lang);
        spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spLang.setAdapter(spinnerAdapter);

For Perticular Spinner item Selection:

int Position = spinnerAdapter.getPosition("Japanese");
spLang.setSelection(Position);

First Create Hashmap for store Key and value pair

HashMap<String ,String> hmLang = new HashMap<String,String>();

Now Add value like this into HashMap :

hmLang.put("english" ,"en");

Here in HashMap key = YourValue and Value = yourKey

@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int position, long id) {
    switch(adapterView.getId())
    {
        case R.id.spLang:
        String lang_Name = adapterView.getItemAtPosition(position).toString();
        String lang_Key = hmLang.get(lang_Name);
        break

    }
