我试图在我的应用程序中添加多个字体系列。以下是添加“inter”字体的代码。
这里是values/typography.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr name="textAppearanceDisplayLargeBold" format="reference" />
    <attr name="textAppearanceDisplayLargeSemiBold" format="reference" />
    <attr name="textAppearanceDisplayLargeMediumBold" format="reference" />

    <style name="TextAppearance.App.DisplayLarge" parent="TextAppearance.Material3.DisplayLarge">
        <item name="fontFamily">@font/inter_font_family</item>
        <item name="fontWeight">400</item>
    </style>

    <style name="TextAppearance.App.DisplayLarge.Bold">
        <item name="fontWeight">700</item>
    </style>

    <style name="TextAppearance.App.DisplayLarge.SemiBold">
        <item name="fontWeight">600</item>
    </style>

    <style name="TextAppearance.App.DisplayLarge.Medium">
        <item name="fontWeight">500</item>
    </style>

</resources>

字符串
这里是font/inter_font_family.xml

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:app="http://schemas.android.com/apk/res-auto">
    <font
        app:font="@font/inter_regular"
        app:fontStyle="normal"
        app:fontWeight="400" />
    <font
        app:font="@font/inter_medium"
        app:fontStyle="normal"
        app:fontWeight="500" />
    <font
        app:font="@font/inter_semibold"
        app:fontStyle="normal"
        app:fontWeight="600" />
    <font
        app:font="@font/inter_bold"
        app:fontStyle="normal"
        app:fontWeight="700" />
</font-family>

型
这里是themes.xml

<style name="AppTheme" parent="Theme.Material3.Light.NoActionBar">

    <item name="textAppearanceDisplayLarge">@style/TextAppearance.App.DisplayLarge</item>
    <item name="textAppearanceDisplayLargeBold">
        @style/TextAppearance.App.DisplayLarge.Bold
    </item>
    <item name="textAppearanceDisplayLargeSemiBold">
        @style/TextAppearance.App.DisplayLarge.SemiBold
    </item>
    <item name="textAppearanceDisplayLargeMediumBold">
        @style/TextAppearance.App.DisplayLarge.Medium
    </item>
</style>

我的主要问题是fontWeight在TextAppearance样式中没有效果。如果我在TextAppearance样式中设置单个字体（inter_bold，inter_light等），它就能工作并显示正确的字体。
