Restore ActionMode after orientation change

Question

I have listfragment which starts actionmode. I am using actionbarsherlock. But when orientation changes, or when I start new activity contextual actionbar disapears. Is there any way to restore it back, without starting it again? In google gmail app it stays on screen whether I rotate phone or go to the detail screen.

The better way is use onSaveInstanceState to save ActionMode state before rotation.

public abstract class MyActivity extends SherlockFragmentActivity{

    private boolean isInActionMode = false;

    @Override
    public void onCreate(Bundle state){
         super.onCreate(state);

         if (state != null && state.getBoolean("ActionMode", false)){
                startActionMode(new MyActionMode());
         }else{
             ///whatever you'd normally do
         }
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
         // Save isInActionMode value
         outState.putBoolean("ActionMode", isInActionMode);

         super.onSaveInstanceState(outState);
    }

    public void onWhateverEventNormallyStartsYourActionMode(){
        startActionMode(new MyActionMode());
    }

    public class MyActionMode implements ActionMode.Callback{

        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            isInActionMode = true;
            ///whatever you'd normally do
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            ///whatever you'd normally do
        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            ///whatever you'd normally do
        }

        @Override
        public void onDestroyActionMode(ActionMode mode) {
            isInActionMode = false;
        }
    }
}
