From e4623cd2a330e3bfb2e5b3a311f47dc984639a8f Mon Sep 17 00:00:00 2001 From: Jason Chang Date: Wed, 28 Aug 2024 18:52:19 +0000 Subject: [PATCH] (1/n) Make the GlifHeader scrollable on FingerprintEnrollEnrolling( UDPFS) layout page. 1. To override GlifLayout's onInflateTemplate() then embedding a ScrollView on GlifHeader. 2. Remove previous hiding the description text snippet 3. Handling UDFPS enroll lottie position problem. 4. Solve the ProgressBar overlapped with FooterBar problem.
