解决方法：

在图形模式下打开资源文件，clean下project，关闭eclipse，然后重新打开eclipse，资源文件即可正常解析

open the layout in graphical layout editor.Clean the project.Keep the layout open in graphical editor, close eclipse and open it again.

The suggestion on comment #42 worked for me, in addition to removing the project library setting:

1. open the layout in graphical layout editor.

2. Clean the project.

3. Remove the project library setting.

4. Keep the layout open in graphical editor, close eclipse and open it again.

5. the layout should work now, you can check the project as library again.
