为什么不能应用thems.xml中的按钮样式？

Question

我现在正在尝试将新字体应用到 entire application。

顺便说一句，虽然在themes.xml中定义了style tag，但是textView是集体应用的，但是字体并没有应用到按钮和芯片等其他视图.

只好直接style=""按钮了，太麻烦了

而且样式不能直接应用到Chip。

这是什么原因？这是一个错误吗？

Answer 1

您可以在 Material 主题中设置按钮样式：

   <item name="materialButtonStyle">@style/ButtonStyle</item>

   <style name="ButtonStyle" parent="Widget.MaterialComponents.Button">
       ...

为什么不能应用thems.xml中的按钮样式？

Why can't the button style in thems.xml be applied?
