本人用的Eclipse，想导入android.support.v7.widget.RecyclerView这个类，从Android Support Library里把RecyclerView作为Library导进了我自己的工程，在Activity里用不会报错，但是在layout里用RecyclerView的话就会报这样的错：
The following classes could not be instantiated:
- android.support.v7.widget.RecyclerView (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.
Error Log里是这样的：
