EditText in CollapsingToolbar with NestedScrollView won’t scroll when the keyboard is open

The problem

What we currently have

• CoordinatorLayout with CollapsingToolbar inside
• The CollapsingToolbar has an ordinary Toolbar inside that displays text
• A NestedScrollView with multiple EditText fields inside of it which actually pushes the CollapsingToolbar to collapse when you try to enter something in the EditText

The actual problem

The problem was that when you tap on one of the EditText fields and the keyboard opens, then you cannot scroll down to the last EditText that is visible so you can enter some text into it. Here is a video demonstrating the problem:

The solution

Actually, the problem was that the parent CoordinatorLayout had the android:fitsSystemWindows flag set to true. This would stop the NestedScrollView from scrolling when the keyboard is visible. It would just stop at the point where the CollapsingToolbarLayout is collapsed and won’t scroll a step more. In order to fix this, you just have to set the fitsSystemWindows flag to false for the root layout in your XML.
