二维码生成与解码

1、编码

     /*参数说明

      String str : 需要编码字符 

      int size : 二维码大小，像素单位

      int onColor : 前景色，整数颜色 如 0xFF000000

      int offColor : 背景色，整数颜色 如 0xFFFFFFFF

      String savepath : 二维保存地址

      String filename : 二维码保存名称

      String logopath : 二维码需要加logo的路径

      String text : 二维码下方的文本内容

      boolean round : 二维码是否为圆角

      boolean transparent : 二维码是否为透明背景
