Android:在TextAppearance中设置fontFamily不起作用

Question

我想要一个带字体的默认标题TextStyle,并且每个继承的样式(HeaderStyle,HeaderTwoStyle)都应该能够显示正确的字体,以防我想要覆盖标题中的字体.但它不起作用......

<style name="Headline1" parent="TextAppearance.AppCompat.Headline">
    <item name="android:textSize">@dimen/font_28sp</item>
    <item name="android:fontFamily">sans-serif</item>
    <item name="android:textColor">@color/headline1</item>
</style>

<style name="HeaderStyle">
    <item name="android:layout_gravity">center_horizontal</item>
    <item name="android:gravity">center</item>
    <item name="android:textAppearance">@style/Headline1</item>
</style>

<style name="HeaderTwoStyle">
    <item name="android:layout_gravity">center_horizontal</item>
    <item name="android:gravity">center</item>
    <item name="android:textAppearance">@style/Headline1</item>
</style>

Answer 1

你应该<style name="HeadLine1.HeaderStyle">在同一个文件中编写 like 来覆盖样式
