In my previous question, I was interested in how to remove the gap between the toolbar and LinearLayout. Good people suggested that you need to install App: elevation = "0dp" in AppBArLayout, and the problem was solved. But the trouble does not come alone, and now, after DrawerLayout has descended under the Toolbar - we have a new gap, the size is much more than the shadow of anything:

And this, notice, the Android Studio template with a curtain, which has not yet had time to make changes, except to lower the curtain under the toolbar.

What is it and how to deal with it?

  • And what do you want to achieve? Why did you change the markup? - Yuriy SPb ♦
  • We want the toolbar not to close when the curtain comes out - Newbie
  • In general, all this used to work this way, but then Google decided that it was necessary to close the toolbar. So you have to run out. Try, for a start, to put some negative margin for NavigationView, returning the markup to its original form - Yuriy Spb ♦

    Yes, it is very similar to the status bar. Most likely Google insight is some kind of hellish hack so that the left menu looks the same on different versions. So yes - it is better to leave the standard behavior. Though, maybe, manipulations with translusentStatusBar attribute in styles will help. But it's better not to go there - everything is bad with backward compatibility - YuriySPb ♦

    I thought so. Thank you for your participation! - Newcomer
