Minimal sample app repro:

Android API version: Android API 31

Material Library version: Material Android Library android-material="1.12.0"

Device: android emulator Virtual Device android 12; and other android 12 Device ,eg: XIAOMI 10S

Inizia con l’AddressInputDialog fornito, il relativo punto di ingresso BottomSheetDialogFragment e il layout TextInputEditText. Riproduci il flusso di input su Android API 31 utilizzando l’XML e Kotlin forniti, quindi confronta il comportamento sui dispositivi segnalati. Il lavoro è completato quando il metodo di input è utilizzabile con uno dei due campi focalizzato, senza introdurre regressioni nella UI del bottom sheet.
