Both View focus (which is triggered by View.requestFocus()) and IME focus (which is internally handled inside InputMethodManager), are implemented as delayed tasks on the UI thread. The goal here is to make sure that InputMethodManager.showSoftInput() always gets called only after the target EditText gained IME focus. This requires some tricks, but is basically a solved problem with ImeAwareEditText introduced by I182b05d3ff59fb3b4732d60d0d5a464f0e0e0235. Here we can just reuse it. Note that ConfirmLockPassword & ChooseLockPassword are the only ones using ScrollToParentEditText. Latter doesn't call IMM.showSoftInput(). Fixes: 62542157 Test: Verified keyboard still shows-up on the ConfirmLock screen. Change-Id: I892d639f3cc5d43db553b682d5278b8ce2fe72da
