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); |
linewidht变量控制四个角的宽度,下图显示的是设置为2时的效果
将ViewfinderView类中代码中vmiddle hmiddle 变量定义下的这两句替换可以变为小十字坐标
canvas.drawRect(hmiddle - 20 , vmiddle - 1 , hmiddle + 20 ,vmiddle + 2 , paint); canvas.drawRect(hmiddle - 1 , vmiddle - 20 , hmiddle + 2 ,vmiddle + 20 , paint); |

再贴一些经典的扫描界面
