Question

I am using Android compat library to show a ActionBar at the top of the screen.
The actionBar contains a refresh button which is a rotating circle if it is pressed.

To activate the rotation of the circle in the actionBar I use following:

getActionBarHelper().setRefreshActionItemState(true);

This works fine, if I call it via a button click or via onOptionsItemSelected().

But if I call it in onCreate or onStart nothing happens. I am wondering why?

Answer 1

Remember that the rotating circle only appears once onCreateOptionsMenu has been executed. It means that it will not appear if you try to execute getActionBarHelper().setRefreshActionItemState(true) on your Activity “onCreate”. If you try on “onResume” it will work. You can use it wherever you need once onCreateOptionsMenu has been executed.

I hope it helps you.
