How to set Spinner Default by its Value instead of Position

Question

I have 1-50 records in the database  I am fetching those data using cursor and set those values to Spinner using Simple Cursor Adapter  Now what i need is i want to set one value say 39th value as default  But not by its position i want to set by its value   I know how to set the spinner default by its position     spinner setSelection 39     will set the spinner to that value   But i didn t have any idea about setting the spinner default by its value text  in the database  I know the values in the database  For eg  books  is one of the value in the spinner  I need to set the spinner default as books   Is there any possible way to do this

If the list you use for the spinner is an object then you can find its position like this

private int selectSpinnerValue( List<Object> ListSpinner,String myString) 
{
    int index = 0;
    for(int i = 0; i < ListSpinner.size(); i++){
      if(ListSpinner.get(i).getValueEquals().equals(myString)){
          index=i;
          break;
      }
    }
    return index;
}

using:

 int index=selectSpinnerValue(ListOfSpinner,StringEquals);
    spinner.setSelection(index,true);

Finally  i solved the problem by using following way  in which the position of the spinner can be get by its string  private int getPostiton String locationid Cursor cursor        int i      cursor moveToFirst         for i 0 i lt  cursor getCount  -1 i                     String locationVal   cursor getString cursor getColumnIndex RoadMoveDataBase LT LOCATION              if locationVal equals locationid                          position   i 1                break                    else                       position   0                    cursor moveToNext               Calling the method       Spinner location2    Spinner findViewById R id spinner1       int location2id   getPostiton cursor getString 3  cursor       location2 setSelection location2id     I hope it will help for some one

Compare string with value from index  private void selectSpinnerValue Spinner spinner  String myString                  int index   0           for int i   0  i  lt  spinner getCount    i                  if spinner getItemAtPosition i  toString   equals myString                     spinner setSelection i                    break
