条码扫描二维码扫描—ZXing android 改进版本

看了Vurtexゞ. 文章《[Android实例] 条码扫描二维码扫描——ZXing android 源码简化 (附:支持中文) 》的基础上对代码进行了修改

1、增加了将代码嵌套入自己工程后传值的办法（初学，如果有更好的方法也希望告诉我，先谢谢了）

2、扫码界面进行了处理（初步实现了现有某些软件的样子，至于长的像谁就不说了）

//画四个角的代码<br>paint.setColor(frameColor);

canvas.drawRect(15 + frame.left, 15 + frame.top,15 + (linewidht + frame.left), 15 + (50 + frame.top), paint);

canvas.drawRect(15 + frame.left, 15 + frame.top,15 + (50 + frame.left), 15 + (linewidht + frame.top), paint);

canvas.drawRect(-15 + ((0 - linewidht) + frame.right),15 + frame.top, -15 + (1 + frame.right),15 + (50 + frame.top), paint);

canvas.drawRect(-15 + (-50 + frame.right), 15 + frame.top, -15+frame.right, 15 + (linewidht + frame.top), paint);

canvas.drawRect(15 + frame.left, -15 + (-49 + frame.bottom),15 + (linewidht + frame.left), -15 + (1 + frame.bottom), paint);

canvas.drawRect(15 + frame.left, -15+ ((0 - linewidht) + frame.bottom), 15 + (50 + frame.left), -15 + (1 + frame.bottom), paint);

canvas.drawRect(-15 + ((0 - linewidht) + frame.right), -15+ (-49 + frame.bottom), -15 + (1 + frame.right), -15+ (1 + frame.bottom), paint);

canvas.drawRect(-15 + (-50 + frame.right), -15+ ((0 - linewidht) + frame.bottom), -15 + frame.right, -15+ (linewidht - (linewidht - 1) + frame.bottom), paint);
