From f7b7426d81c5365473d00362cf158aa5ae35cee3 Mon Sep 17 00:00:00 2001 From: Adrian Roos Date: Wed, 22 Nov 2017 14:21:01 +0100 Subject: [PATCH] Display Cutout: Fix ActionBarOverlayLayout to properly dispatch cutout ActionBarOverlayLayout used to drop WindowInsets, extract the content insets as a rect, and then dispatch a modified rect to the content view; this because there was no way to retarget the WindowInsets to the content view, and the WindowInsets were not truly immutable. That means however, that other kinds of insets than the content insets do not get dispatched, such as the display cutout. To fix this, we add APIs to inset WindowInsets, make them immutable. Note that a similar change is needed for the support lib.
