What is the difference between actionBar back button and android back button? Because it's seems that the ActionBar back button which is called with:
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
it works way better...
example: when I press the ActionBar back button the animations are there, but if I press the default back button they aren't.
I can change theme from a preference activity: If I go back with the ActionBar back button the colors instantly changed, but with the default I have to restart the app....
how can I make my default back button to behave like the ActionBar one?
When you press the Back button, the current destination is popped off the top of the back stack, and you then navigate to the previous destination. The Up button appears in the app bar at the top of the screen.
Show back button using actionBar. setDisplayHomeAsUpEnabled(true) this will enable the back button. Custom the back event at onOptionsItemSelected. This will enable the back function to the button on the press.
getActionBar(). setDisplayShowHomeEnabled(false); //disable back button getActionBar(). setHomeButtonEnabled(false); In a older android phone, the back button is removed with these two code lines.
The android back button navigates "back". The nav bar button navigates "up". Up navigation always leads you to the same app you were on, just a different activity. Back can change app AND activity.
The ActionBar "back" button is actually an "Up" button and it should take you to higher level on your app's navigation hierarchy. The back button takes you to the last place you were looking at.
Another great tip to better undertand this is that the "Up" button should always take you to a place on your app, while the back button might take you to another app.
