问题描述
迁移到AndroidX时，我遇到了这个问题:
When migrating to AndroidX I faced this problem:
Java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.mandarine.android/com.mandarine.android.features.root.RootActivity}:
android.view.InflateException: Binary XML file line #18: Binary XML file line #18:
Error inflating class android.support.design.widget.AppBarLayout
推荐答案
除非实现旧的支持库并启用Jetifier，否则必须重命名XML中的所有支持类.
Unless you implement the old support libraries and enable Jetifier, you have to rename all your support classes in XML.
android.support.design.widget.AppBarLayout现在是com.google.android.material.appbar.AppBarLayout.
为此，您可能需要在build.gradle中使用implementation 'com.google.android.material:material:1.0.0-beta01'.
You may need to use implementation 'com.google.android.material:material:1.0.0-beta01' in your build.gradle for this.
使用支持库查找XML中的任何其他视图，然后重命名标签以匹配其AndroidX版本.您只需在Google中搜索"ClassName AndroidX"，即可找到该类的文档.
Look for any other Views in XML using the support library and rename the tags to match their AndroidX versions. You can simply search "ClassName AndroidX" in Google and you'll find the documentation for that class.
