Answer 1

更新您的应用主题以继承其中一个主题:

Theme.MaterialComponents
Theme.MaterialComponents.NoActionBar
Theme.MaterialComponents.Light
Theme.MaterialComponents.Light.NoActionBar
Theme.MaterialComponents.Light.DarkActionBar

例如:

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

注意:使用"材料组件"主题可启用自定义视图inflater

Answer 2

您可以像这样在xml布局中添加@ style / Theme.MaterialComponents.Light样式属性：

<com.google.android.material.chip.Chip
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="chip"
android:theme="@style/Theme.MaterialComponents.Light"/>

Answer 3

将以下新主题属性添加到您现有的应用程序主题：

<style name="Theme.MyApp" parent="Theme.AppCompat">

    <!-- Original AppCompat attributes. -->
    <item name="colorPrimary">@color/my_app_primary_color</item>
    <item name="colorPrimaryDark">@color/my_app_primary_dark_color</item>
    <item name="colorAccent">@color/my_app_accent_color</item>

    <!-- New MaterialComponents attributes. -->
    <item name="colorSecondary">?attr/colorPrimary</item>
    <item name="scrimBackground">@color/mtrl_scrim_color</item>
    <item name="textAppearanceHeadline1">@style/TextAppearance.MaterialComponents.Headline1</item>
    <item name="textAppearanceHeadline2">@style/TextAppearance.MaterialComponents.Headline2</item>
    <item name="textAppearanceHeadline3">@style/TextAppearance.MaterialComponents.Headline3</item>
    <item name="textAppearanceHeadline4">@style/TextAppearance.MaterialComponents.Headline4</item>
    <item name="textAppearanceHeadline5">@style/TextAppearance.MaterialComponents.Headline5</item>
    <item name="textAppearanceHeadline6">@style/TextAppearance.MaterialComponents.Headline6</item>
    <item name="textAppearanceSubtitle1">@style/TextAppearance.MaterialComponents.Subtitle1</item>
    <item name="textAppearanceSubtitle2">@style/TextAppearance.MaterialComponents.Subtitle2</item>
    <item name="textAppearanceBody1">@style/TextAppearance.MaterialComponents.Body1</item>
    <item name="textAppearanceBody2">@style/TextAppearance.MaterialComponents.Body2</item>
    <item name="textAppearanceCaption">@style/TextAppearance.MaterialComponents.Caption</item>
    <item name="textAppearanceButton">@style/TextAppearance.MaterialComponents.Button</item>
