Programmatically show Toolbar after hidden by scrolling (Android Design Library)

Question

I have the following layout: a drawer, with the main content view having a AppBarLayout, RecyclerView and a TextView. When I scroll the recycler, the toolbar is correctly hi

Answer 1

You can do it by accessing to the AppBarLayout that contains your Toolbar

Here is an example:

if (mToolbar.getParent() instanceof AppBarLayout){
  ((AppBarLayout)mToolbar.getParent()).setExpanded(true,true);
}

setExpanded(expand,animation) will do the work. You can also have a a reference to the AppBarLayout instead of call the getParent from the toolbar.
