android.view.InflateException: Binary XML file line自定义view的构造函数引起

自定义view的构造函数问题

如果是xml文件引入必须实现带AttributeSet属性参数的构造函数，否则报此错误

 //Simple constructor to use when creating a view from code View(Context context)      //Constructor that is called when inflating a view from XML View(Context context, AttributeSet attrs)      //Perform inflation from XML and apply a class-specific base style View(Context context, AttributeSet attrs, int defStyle)
