Answer 1

As far as I know there is nothing build in that does this for you. However you could have a look at the Google IO sourcecode, especially the BaseActivity. Search for "auto hide" or look at onMainContentScrolled

In order to hide the Toolbar your can just do something like this:

toolbar.animate().translationY(-toolbar.getBottom()).setInterpolator(new AccelerateInterpolator()).start();

If you want to show it again you call:

toolbar.animate().translationY(0).setInterpolator(new DecelerateInterpolator()).start();
