我见过有同样问题的人，他们说 .replace() 以及我使用fragmentManager.beginTransaction() 构建 fragment 和容器的方式有问题。代替 (R.id.container, new Fragment()).commit(); 我必须以其他方式做到这一点，我将其实现到我的代码中，但我仍然收到错误。 错误:

最佳答案
No view found for id 0x7f0d00aa (mcshreker.pocketmath:id/content_main_container)
检查 content_main_container 是否在您的 activity_main 布局中定义
