Answer 1

因为您的错误日志有以下行

android.view.InflateException: Binary XML file line #17: Binary XML file line #17: Error inflating class android.support.design.widget.CollapsingToolbarLayout at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2913)

异常 - InflateException

XML 文件中的第 17 行错误。

同时 膨胀 CollapsingToolbarLayout
