populate custom spinner from strings xml array

Question

I have a custom spinner which is replacing my default spinner which was populated by hard coded values in my strings xml.

I have used my custom spinner and populated it dynamically in java but i don't need to do this for this one.

Do i have to populate a list then add it to the spinner in java? and if so how do i populate a list from strings.xml array element?

    List<String> spinnerList = new ArrayList<String>();
    //spinnerList.addAll(R.array.array_spinner);error here, doesnt like this?????????????
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.spinner_custom, spinnerList);
    spinnerSports.setAdapter(adapter);

<resources>
    <string-array name="array_custspinner">
        <item>item1</item>
        <item>item2</item>
    </string-array>
</resources>

//spinnerList.addAll(R.array.array_spinner);error here, doesnt like this?????????????

yes it is correct. addAll is expecting a Collection of the same type of your List, String in your case. But you are providing an int, the id of array you want to use. Use

List<String> spinnerList = new ArrayList<String>
      (Arrays.asList(getResources().getStringArray(R.array.array_custspinner)));

this way you get a modifiable List<String> which contains all the strings you defined in you array_custspinner
