我是Android开发的新手，我在进行此练习时创建一个基本活动（Android 4.4 kitkat），然后删除TextView并在CoordinatorLayout中添加ListView并以这种方式编程Floating action Button您单击它，它将在列表中添加当前时间日期/月份/年份。 IDE未显示任何语法错误，并且一切似乎都还不错，我正在运行最新版本的Android Studio（3.3.1），但是当我在onePlus（Android 8）上运行该应用程序时，它根本无法打开（ABC已停止-再次打开应用程序），我尝试清理/重建。
但是，当我单击我的IDE右下角的按钮时，它说发生了内部IDE错误，并且在单击它之后，对我来说显示了一些不堪重负的东西：
