how to hide up button in actionbar

Question

I would like to do an edit mode, in the style of the tablet gmail app. If the user presses the edit button on the actionbar, than I would like to show him/her an action view

Answer 1

Though it's an older post, I would like to share an answer which worked for me.

To hide the UP button in actionbar, use the following in OnCreateOptionsMenu:

if (getSupportActionBar() != 
           getSupportActionBar().hide();
       }

To remove the UP button in actionbar, use the following in OnCreateOptionsMenu:

if (getSupportActionBar() != 
           getSupportActionBar().setDisplayHomeAsUpEnabled(false);
       }

I hope it will help newbies.
