Android材质设计-添加样式时出错

Question

我正在尝试向TextInputLayout添加样式，但是当我选择要添加的任何样式时，我的应用程序就会崩溃。没有任何样式都很好。

<com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        app:passwordToggleEnabled="true"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
        >

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:hint="Password"
            android:inputType="textPassword"> 

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

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

也与任何材质（按钮等）相同，我不能使用样式。

我的实现：

implementation 'com.google.android.material:material:1.0.0'

Answer 1

将您的库更新为1.1.0

实现'com.google.android.material：material：1.1.0'

Answer 2

更新至1.1.0，但仍相同。

Answer 3

查看堆栈跟踪，了解到您没有使用Material Theme：

Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).

您可以如下在AppTheme中添加/更改styles：

<style name="AppTheme" parent="Theme.MaterialComponents.*">
    <!-- Add attributes here -->
</style>
