It is very possible that your android project has lost all its contents because eclipse problems, have you cloned the project?.
很有可能您的android项目已经丢失了所有的内容，因为eclipse问题，您已经克隆了这个项目吗?
Open the file activity_main.xml with any plain text editor, such as notepad. Check if there is something inside, if you can not recover it is empty.
activity_main打开文件。xml与任何纯文本编辑器，如记事本。检查里面是否有东西，如果你不能恢复，它是空的。
I hope they solve and have a backup of the project.
我希望他们能解决问题，并对项目进行备份。
If you need help tell me and I will try to solve the problem with you.
如果你需要帮助，告诉我，我会尽力解决你的问题。
