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

If you're on API level 14 or above and are not using ActionbarSherlock, this code in onCreateOptionsMenu will disable the up button, remove the left caret, and remove the icon:

ActionBar actionBar = getActionBar();
if (actionBar != null) {
    actionBar.setHomeButtonEnabled(false); // disable the button
    actionBar.setDisplayHomeAsUpEnabled(false); // remove the left caret
    actionBar.setDisplayShowHomeEnabled(false); // remove the icon
}

Answer 2

This worked for me, though its a slight change in the above mentioned solution

android.support.v7.app.ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.setHomeButtonEnabled(false); // disable the button
            actionBar.setDisplayHomeAsUpEnabled(false); // remove the left caret
            actionBar.setDisplayShowHomeEnabled(false); // remove the icon
        }

Answer 3

You were almost there. To hide the icon/logo completely, use setDisplayShowHomeEnabled(false). The call you're using just removes the little arrow that indicates that the icon acts as an "up" button also.

Answer 4

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.
