Spinner's onItemSelected callback called twice after a rotation if non-zero position is selected

Question

When I create my activity, I setup a Spinner, assigning it a listener and an initial value. I know that the onItemSelected callback is called automatically during a

Answer 1

This is what i did:

Do a local variable

Boolean changeSpinner = true;

On the saveInstanceMethod save the selected item position of the spinner

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("ItemSelect",mySpinner.getSelectedItemPosition());
}

Then on the activity created get that int from savedInstanceState and if the int is != 0 then set the boolean variable on false;

@Override
    public void onActivityCreated(Bundle savedInstanceState) {

    if (savedInstanceState!=null) {
        if (savedInstanceState.getInt("ItemSelect")!=0) {
           changeSpinner = false;
        }
    }

}

And for last on the OnItemSelected from the spinner do this

mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView parent,android.view.View v, int position, long id) {
        if (changeSpinner) {
           [...]
        } else {
           changeSpinner= true;
        }
    });

So, the first time when is called is not going to do anything, just make the boolean variable true, and the second time is going to execute the code. Maybe not the best solution but it work.
