This answer
Buttons in Lollipop and higher have a default elevation to them which causes them to always draw on top. You can change this by overriding the default StateListAnimator.

Problem
I have FrameLayout like this: ``` <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="changeColor" android:text="new button"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="some text"/> </FrameLayout> ``` The problem is that the button is displayed on top while FrameLayout class overview tells us this: "Child views are drawn in a stack, with the most recently added child on top".
