get id of an item in spinner

I have this in my values xml file:

<string-array name="ben_country_list">
    <item id="103">India</item>
    <item id="210">Sri Lanka</item>
    <item id="235">United Kingdom</item>
    <item id="76">France</item>
    <item id="216">Switzerland</item>
    <item id="200">Singapore</item>
    <item id="234">United Arab Emirates</item>
</string-array>

I want to get country's ID. I tried with below code:

final Spinner mBenCountry = (Spinner) findViewById(R.id.country_spinner);
mBenCountry.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        final long ben_country = mBenCountry.getSelectedItemPosition();
        final long ben_country2 = parentView.getSelectedItemId();
        System.out.println(ben_country); // This one gives me position like 0,1,2...
        System.out.println(ben_country2); // Output: same as above...
    }
});

I want to get actual IDs of the selected item. For example, if user selects united kingdom then it should print 235. I don't want name of that item.

Thanks for any help.

Make a separate integer-array in XML for the ids:

<?xml version="1.0" encoding="utf-8"?>
<resources>
     <integer-array name="ben_country_ids">
          <item>103</item>
          <item>210</item>
          <item>235</item>
          <item>76</item>
          <item>216</item>
          <item>200</item>
          <item>234</item>
     </integer-array>
</resources>

Get the int array in code:

final int[] benCountryIds = getResources().getIntArray(R.array.ben_country_ids);

Using the position get the correct id from the array in onItemSelected:

int countryId = benCountryIds[position];

First of all, android string-array XML structure doesn't support key/value pairs for item entries. So, you have to use other data source etc.: database table, CSV file or whatever else. Then load data into some collection and then pass it to custom adapter.

Once you have the selected item position, you can do this:

mBenCountry.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {

        switch (id) {
            case 103 : 
                System.out.println("India");
                break;
            case 210:
                System.out.println("Sri Lanka");
                break;
.
.
.
}
