Android Studio导入错误的程序包

Question

I recently migrated to Android Studio, but it still isn't polished (in my opinion). When I was making a call to a new thread and trying to get a callback to the UI thread, it suddenly complained that there was no post method in the Handler class.

Then I noticed that the IDE had imported java.util.logging.Handler instead of android.os.Handler . Has anyone encountered this same problem before and how do you get Android Studio to import properly?

是的，我遇到了同样的问题，但是简单地在使用自动完成时，按Ctrl + 空格键两次（检查您的键盘映射） ，它将显示所有已将其包命名为Handler的类，并选择适当的类
