How to set text color of elements in Spinner Android


I'm having trouble adjusting the text color for Spinner. I saw a few examples, but most of them have an ArrayAdapter and String from strings.xmlin res folder, since my Spinner elements are retrieved from the SQLite database, so I think this may not help.

Here are my Spinner PersonalInformation.java codes

public class PersonalInformation extends Activity
{
    EditText txtLikes, txtDislikes, txtType, txtDate;
    Button btnView, btnBack;
    Spinner nameSpinner;    

    final Context context = this;

    private int namesSpinnerId;        

    LikesDBAdapter likeDB = new LikesDBAdapter(this);
    DislikesDBAdapter dlikeDB = new DislikesDBAdapter(this);


    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.info);

        BuddyDBAdapter buddyDB = new BuddyDBAdapter(this);
        buddyDB.open();

        Cursor friendsCursor = buddyDB.getAllNames();
        startManagingCursor(friendsCursor); 

        String[] from = new String[]{BuddyDBAdapter.KEY_NAME};
        int[] to = new int[]{R.id.name};

        SimpleCursorAdapter friendsCursorAdapter = new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, friendsCursor, from, to);
        friendsCursorAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        nameSpinner = (Spinner)findViewById(R.id.nameSpinner);
        nameSpinner.setAdapter(friendsCursorAdapter);
        //buddyDB.close();


        nameSpinner.setOnItemSelectedListener(new OnItemSelectedListener()
            {
                 @Override
                 public void onItemSelected(AdapterView<?> parent, View view, int pos, long id)
                 {
                     Cursor c = (Cursor)parent.getItemAtPosition(pos);
                     namesSpinnerId = c.getInt(c.getColumnIndexOrThrow(BuddyDBAdapter.KEY_ROWID));
                 }

                @Override
                public void onNothingSelected(AdapterView<?> parent)
                {
                    // TODO Auto-generated method stub

                }
            });
        buddyDB.close();

And these are the Spinner linker codes in the info.xml file

<Spinner
        style="@style/SpinnerStyle"
        android:id="@+id/nameSpinner"        
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:prompt="@string/friends_prompt"
        android:textColor="@color/green" />

Please help me how to set the text color of elements in Spinner.
I would appreciate any help. Thanks.! =)
