为了使用Chip和ChipGroup,我设置应用程序样式扩展"Theme.MaterialComponents.Light.NoActionBar"int manifests.xml,然后我设置Button"android:background"attr,但它没有效果!为什么？我该怎么办？

这是我的风格:

  <style name="AppBaseTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <item name="colorPrimary">@color/primary_material_light</item>
    <item name="colorPrimaryDark">@color/header_color</item>
    <item name="actionBarSize">48dp</item>
    <item name="android:screenOrientation">portrait</item>
    <!--<item name="buttonStyle">@style/AntButton</item>-->
    <!--<item name="materialButtonStyle">@style/AntButton</item>-->
    <!--<item name="android:button"></item>-->
    <!--<item name="android:progressTint">@color/ffc000</item>-->
    <item name="colorAccent">@color/ffc000</item>
</style>


<style name="AntButton" parent="android:Widget">
    <item name="android:background">@drawable/abc_btn_default_mtrl_shape</item>
    <item name="android:textAppearance">?android:attr/textAppearanceButton</item>
    <item name="android:minHeight">48dip</item>
    <item name="android:minWidth">88dip</item>
    <item name="android:focusable">true</item>
    <item name="android:clickable">true</item>
    <item name="android:gravity">center_vertical|center_horizontal</item>
    <!--<item name="android:colorButtonNormal">@color/white</item>-->
</style>

我试图改变buttonStyle和materialButtonStyle,但也没有效果!

这是我的布局xml:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/ll_popup"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="@color/white"
        android:divider="@drawable/shape_divider_05dp"
        android:orientation="vertical"
        android:showDividers="beginning|middle">

        <!--only can use backgroundTint to change background color-->
        <Button
            android:id="@+id/item_popupwindows_Photo"
            android:layout_width="match_parent"
            android:layout_height="55dp"
            android:backgroundTint="@color/white"
            android:text="Pictrue"
            android:textColor="@color/c_666666"
            android:textSize="16sp" />

        <!--background not effect !!--> …
