Answer 1

create a strings.xml file in res/values/ and add the following:

<?xml version="1.0" encoding="utf-8"?>
  <resources>
<string name="spinnerstr">Choose an item</string>
<string-array name="spinner_array">
    <item>apple</item>
    <item>orange</item>
    <item>grapes</item>
</string-array>

In your spinner.java, add the followoing:

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
        this, R.array.spinner_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

Hope this will help you.
