Best way of getting key & value from Spinner

Question

There are many methods for getting

Key

&

Value

from

Array

.

But what is best way getting

Key

&

Value

from an

Array

in

arrays.xml

like

key => value

via spinner?

arrays.xml:

<resources>

    <string-array name="settings_listofitems">

        <item name="1">item1</item>

        <item name="2">item2</item>

    </string-array>  

</resources>

When i use code in below i get only

item value

. But i need item

key value

too:

Spinner spinner1 = (Spinner)findViewById(R.id.spinner1);

String itemvalue = getResources().getStringArray(R.array.settings_listofitems)[spinner1.getSelectedItemPosition()];

Any help is highly appreciated.

You can have Keys and Values both in separate Arrays, like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="settings_listofitems_keys">
    <item>1</item>
    <item>2</item>
</string-array>

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

And then parse them like this :

Spinner spinner1 = (Spinner)findViewById(R.id.spinner1);
String itemvalue = getResources().getStringArray(R.array.settings_listofitems_values)[spinner1.getSelectedItemPosition()];
String keyvalue = getResources().getStringArray(R.array.settings_listofitems_keys)[spinner1.getSelectedItemPosition()];

I hope this helps.
