Display back button on action bar

android, android-actionbar, android-homebutton

Solution

well this is simple one to show back button

actionBar.setDisplayHomeAsUpEnabled(true);

and then you can custom the back event at onOptionsItemSelected

case android.R.id.home:
this.finish();
return true;

Problem

I'm trying to display a `Back button` on the `Action bar` to move previous page/activity or to the main page (first opening). And I can not do it. my code. ``` ActionBar actionBar = getActionBar(); actionBar.setHomeButtonEnabled(true); ``` the code is in `onCreate`.
