Situation réelle de la question

J'ai un formulaire d'adresse simple comme celui-ci :

Java :

public class NewAddressActivity extends AppCompatActivity {

private TextInputLayout mStreetLayout;

private TextInputLayout mNeighborhoodLayout;
private TextInputLayout mCityLayout;
private TextInputLayout mStateLayout;
private TextInputLayout mCepLayout;

private EditText mNumberText;
private EditText mComplementText;
private EditText mNeighborhoodText;

private Address mAddressEditing;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

Comment vous pouvez voir sur java, mAddressEditing est reçue de l'intention, quand elle n'est pas nulle, cela signifie que l'utilisateur veut modifier son adresse.

Tous les champs sont remplis comme prévu, mais lorsque je tape sur un texte à modifier pour changer sa valeur, le système se bloque...

Crash :

FATAL EXCEPTION: main 
Process: br.com.fornaro.armariovirtual, PID: 5540
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.getBoundsOnScreen(android.graphics.Rect)' on a null object reference at android.app.assist.AssistStructure$WindowNode.<init>(AssistStructure.java:484)

Je n'ai aucune idée de la raison pour laquelle il se plante.

Étapes à reproduire : 1. Modifier une adresse à partir de l'écran précédent en passant l'objet Adresse comme paramètre sur l'intention. 2. Cliquez sur un texte à modifier pour changer sa valeur. 3. Crash !

Le problème est un bug connu d'Android. D'après les suggestions du Google Issue Tracker, le réglage de l'indice sur le TextInputEditText semble être à l'origine du plantage. Le fait de définir l'indice uniquement sur le TextInputLayout corrige le problème.

Ce problème ne se produit que SI l'indice est défini sur le EditText imbriqué imbriqué dans le TextInputLayout. J'ai résolu le problème en définissant l'indice sur l'élément TextInputLayout.

Définissez l'indice sur le TextInputLayout au lieu de l'EditText imbriqué. Il ne se plantera pas.

<android.support.design.widget.TextInputLayout
                    android:id="@+id/til1"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:hint="Phone Number">
                    <EditText
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:id="@+id/login_phone"

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

android:importantForAutofill="noExcludeDescendants"
