原因: 引用了 MaterialTheme 的资源所以必须引用MaterialTheme的Theme

解决:MaterialCardView 所以的Activity 引用Theme.MaterialComponents下的Theme

 <activity
        android:name=".module.main.ui.activity.MainActivity"
        android:theme="@style/Theme.MaterialComponents.Light.NoActionBar"
        android:configChanges="keyboardHidden|screenSize|orientation|smallestScreenSize|screenLayout"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="stateHidden|adjustResize"
        tools:ignore="LockedOrientationActivity" >
