Root cause: The width and height of animated image are wrap_content. It causes the gif or drawable which are non-transparent background to have a little weird display under dark mode. Next: 1. Revise the width from wrap_content to match_parent, and add the fit center scale type. 2. Correct the function usage Bug: 155946967 Test: manual test Change-Id: I7470efb945a2b3bedb695e1b6f34475c6f190f9d
