Android studio-无法运行我的应用程序,我的项目怎么了?

我刚刚开始涉猎Java,所以请暂时保留有关不良代码实践的讲座。

我最近的项目一直遇到很多问题,一开始我根本无法显示任何布局对象。经过几个小时的搜索后,我解决了该问题。

但是,现在我在实际尝试在模拟器上运行项目时遇到问题。我在其他线程上看到过一些建议,例如关闭即时运行,删除.idea和gradle文件夹,然后重建并与gradle等同步。到目前为止,这些都不对我有用。

我只想问一下我的代码是否存在任何问题(除了实践/效率方面不是很好),这会阻止我的代码运行。 (请参见下面的事件日志代码)

我感到困惑的原因是,在构建项目时我没有出现任何错误,但是我无法运行该应用程序(还尝试过构建APK文件并在我的实际手机上运行它,但这是行不通的要么。)
