java.lang.IllegalArgumentException:该组件要求您指定一个有效的android:textAppearance属性 [英] java.lang.IllegalArgumentException: This component requires that you specify a valid android:textAppearance attribute

问题描述

我的一个布局文件中有一个com.google.android.material.button.MaterialButton组件，当我使用最新版本的Material Components库(com.google.android.material:材质:1.0.0-alpha3):

I have a com.google.android.material.button.MaterialButton component in one of my layout file and I get this error when I am using the latest version of the Material Components library (com.google.android.material:material:1.0.0-alpha3):

java.lang.IllegalArgumentException:该组件要求您指定有效的android:textAppearance属性.

在1.0.0-alpha1中不存在.这是库中的错误，还是我现在应该只指定textAppearance属性?

It wasn't present in 1.0.0-alpha1. Is this a bug in the library or should I just specify a textAppearance attribute from now?
