Comme vous pouvez le voir sur Java, la variable mAddressEditing est reçue d’intention. Quand elle n’est pas nulle, cela signifie que l’utilisateur veut modifier son adresse.

Tous les champs sont remplis comme prévu. Toutefois, lorsque je tape sur un texte de texte pour en modifier la valeur, il se bloque ...

Crash:

FATAL EXCEPTION: main 
Process: br.com.fornaro.armariovirtual, PID: 5540

Je ne sais pas pourquoi il s'écrase.

Étapes à suivre pour la reproduction: 1. Modifiez une adresse à partir de l'écran précédent en transmettant l'objet Adresse en tant que paramètre d'intention. 2. Cliquez sur un texte à modifier pour en modifier la valeur 3. Crash!

L'ajout de ce code sur chaque texte modifié a résolu mon problème:

Android:importantForAutofill="noExcludeDescendants"

Douglas Fornaro

Le problème est connu: Android bug. D'après les suggestions de Google pour le suivi des problèmes, définir l'indicateur sur TextInputEditText semble provoquer le blocage. Définir l'indicateur uniquement sur TextInputLayout corrige le blocage.

Ce problème ne se produit que si l'indicateur est défini sur le texte d'édition imbriqué dans TextInputLayout. Je l'ai résolu en définissant l'indicateur sur TextInputLayout.

Définissez l'indicateur sur TextInputLayout au lieu de EditText imbriqué. Il ne va pas s'écraser.
