我在android中创建项目时遇到这种类型的异常我有一个主要活动和一些片段，但是当我运行应用程序时，我得到的错误就像这些我在这里粘贴错误，

在你的例外中，只是试着关注这些行，
java.lang.IllegalArgumentException: No view found for id 0x7f0d008e
在您的主要活动代码中，您已在id 0x7f0d008e上应用了操作，但它不在您的xml文件中。
答案 1 :(得分：0)
正如其他用户所说，您必须专注于缺少ID视图，并且您必须尝试找出一个缺少的ID。第二件事是你在mainactivity中使用片段然后只是尝试看到片段的xml，我认为缺少id是指片段视图的元素之一。
