Android NullPointerException - Spinner onItemSelected `view` parameter is null after rotating

Question

Answer 1

public void onItemSelected(AdapterView parent, View view, int position, long id)

adapterView is referenced to Spinner, not the item you clicked, you should cast the "view" parameter instead.

@Rock Lee After rotated the layout would be refresh, you should resetup the spinner in some callback function like onConfigurationChanged(Configuration newConfig), Android listview disappears after screen rotation
