Error inflating class com.google.android.material.textfield.TextInputLayout

问题

This is my app theme: <style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">

I got an inflate error caused by a not using a desired theme. In the Manifest I didn't overwrite the theme for the activity that I got this error, so the AppTheme definded in styles.xml is used.

Error:

        at com.google.android.material.internal.ThemeEnforcement.obtainTintedStyledAttributes(ThemeEnforcement.java:116)

And this is my xml:

  <com.google.android.material.textfield.TextInputLayout
                        android:id="@+id/inputFirstName"
                        style="@style/EditText.OutlinedBox"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_marginStart="16dp"
                        android:layout_marginTop="10dp"
                        android:layout_marginEnd="16dp"
                        android:visibility="gone"
                        app:boxStrokeColor="@color/colorBrand"
                        app:layout_constraintEnd_toEndOf="parent"
                        app:layout_constraintStart_toStartOf="parent">

and the EditText style:

 <style name="EditText.OutlinedBox" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
        <item name="android:minHeight">56dp</item>
        <item name="android:textSize">18sp</item>
        <item name="android:fontFamily">@font/nunito_regular</item>
        <item name="android:textColorHint">@color/colorTextSecondary</item>
        <item name="hintTextColor">@color/colorBrand</item>
        <item name="hintEnabled">true</item>
    </style>

target sdk of the app is 29 and I use material_design_components_version = '1.1.0-alpha08'

EDIT:

from app/gradle

    implementation(
        "androidx.appcompat:appcompat:$appcompat_version",
        "androidx.constraintlayout:constraintlayout:$constraintlayout_version",
        "com.google.android.material:material:$material_design_components_version"
)

Manifest:

<application
    android:name=".application.BaseApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    android:usesCleartextTraffic="true">

Theme:

</style>

I'm facing the same issue. The problem is with the material version. try change your version alpha06 and it should fix it.

implementation 'com.google.android.material:material:1.1.0-alpha06'
