This may be a bug, but not if there is a way to attach the view to the
window manager.
I have a class extending AlertDialog. The dialog has a drop down menu
that allows user to choose item. When the orientation is changed with
the drop down menu displayed, I get the exception listed below. I set
up the drop down view/resources in onStart() of the Dialog, as shown:
protected void onStart() {
super.onStart();
mySpinner = (Spinner) findViewById(R.id.spinner);
mySpinnerAdapter = new ArrayAdapter<Tee>(context,
android.R.layout.simple_spinner_item, myList);
mySpinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mySpinner.setAdapter(mySpinnerAdapter);
}
This error is occuring because, though this Dialog is managed by the
Activity (using onCreateDialog, onPrepareDialog, etc.), the View
generated by the SpinnerAdapter is not. I see there is a way to grab
individual items from the drop down view, but not get the view itself
(to attach it).
How can the SpinnerAdapter not cause problems on any orientation change?
