If you are setting the spinner values by arraylist or array you can set the spinner's selection by using the index of the value.

String myString = "some value"; //the value you want the position for

ArrayAdapter myAdap = (ArrayAdapter) mySpinner.getAdapter(); //cast to an ArrayAdapter

int spinnerPosition = myAdap.getPosition(myString);

//set the default according to value
spinner.setSelection(spinnerPosition);

see the link How to set selected item of Spinner by value, not by position?

If the list you use for the spinner is an object then you can find its position like this  private int selectSpinnerValue  List lt Object gt  ListSpinner String myString         int index   0      for int i   0  i  lt  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
