From 171b4c4cbe6ba5af3fd7df87d227eda44e308727 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Mon, 19 Jun 2017 23:10:44 -0700 Subject: [PATCH] screen_ui: Allow setting screen margin space. We already have outer_width and outer_height in wear UI, and x_offset and y_offset in VR UI. This CL adds margin_width_ and margin_height_ to their base class (ScreenRecoveryUI) to shorten the gap. This will be in general useful for round or round-cornered screens. Move the density computation to ScreenRecoveryUI ctor so that the value can be used earlier. Bug: 62732748 Test: Setting and not setting margin_{width,height}_ on angler. Check the recovery texts (recovery menu as well as 'View recovery logs').
