    }

        super( context );
    }

    public CustomImageButton( Context context, AttributeSet attrs ) {
        super( context, attrs );
    }

    public CustomImageButton( Context context, AttributeSet attrs, int defStyle ) {
        super( context, attrs, defStyle );
        // TODO Auto-generated constructor stub
    }
