Android Material TextInputLayout 样式 OutlinedBox 不工作

Android Material TextInputLayout Style OutlinedBox Not Working

我使用 Material 带有 OutlinedBox 样式的 TextInputLayout

@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox

启动模拟器时无法正常工作“不幸已停止。”

implementation 'com.google.android.material:material:1.2.0'



<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingLeft="15dp"
    android:paddingRight="15dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintHorizontal_bias="0.5"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Username"
        android:inputType="text" />

</com.google.android.material.textfield.TextInputLayout>

如果您查看 运行 输出,您将看到:

The style on this component requires your app theme to be Theme.MaterialComponents

所以我们可以更改继承自 Theme.MaterialComponents 的应用主题:

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar.Bridge">

详细解释是here.
