Answer 1

看起来您在布局中使用的 RecycleView 标签不正确。你这样写<RecycleView ... , 但你需要写 <android.support.v7.widget.RecyclerView>

您在 xml 中使用的所有 View ，inflater 查看 android.view 包。所以你有异常(exception):

java.lang.ClassNotFoundException: Didn't find class "android.view.RecyclerView"

因为 RecyclerView 类位于 android.suport.v7.widget 包中。在这种情况下，您需要使用 View 类的完整限定名称。
