Error : android.view.InflateException: Binary XML file line #Num:Error inflating class className

-------------

해결: 

public MenuSlideView(Context context) {

        super(context);

     }

     public MenuSlideView(Context context, AttributeSet attrs) {

        super(context, attrs);

     }

     이 두개의 생성자를 꼭 생성시켜야함.
