Answer 1

如果运行堆栈跟踪的原因，您可以看到它无法加载NavigationView。

试着倒读stacktrace的原因，以更好地了解原因。

1）原因：Android.View.InflateException：二进制XML文件第18行：inflating类ImageView时出错。

2）原因：java.lang.Reflect.InvocationTargetException

3）原因：Android.View.InflateException：二进制XML文件第16行：inflating类Android.Support.Design.Widget.NavigationView时出错

这使我认为，在NavigationView中，它试图加载一个不存在或ID不正确的imageview。

我还假设它发生在通货膨胀期间，与app:headerlayout=“@layout/nav_header_main_list”有关。

检查您的nav_header_main_list资源以查找ID不正确的imageview。
