[自定义属性说明](#自定义属性说明)\n* [接口说明](#接口说明)\n* [关于我](#关于我)\n\n## 功能介绍\n根据[之前公司](http://www.iqegg.com)的产品需求，参考 [barcodescanner](https://github.com/dm77/barcodescanner) 改的，希望能帮助到有生成二维码、扫描二维码、识别图片二维码等需求的猿友。修改幅度较大，也就没准备针对 [barcodescanner](https://github.com/dm77/barcodescanner) 库提交PR。\n\n- [x] 可定制各式各样的扫描框\n- [x] 可定制全屏扫描或只识别扫描框区域内码\n- [x] 可定制要识别的码的格式（详细用法查看 TestScanActivity 中的 onClick 方法）\n- [x] 可以控制闪光灯，方便夜间使用\n- [x] 可以设置用前置摄像头扫描\n- [x] 可以二指缩放预览\n- [x] 可以监听环境亮度，提示用户打开、关闭闪光灯\n- [x] 识别到比较小的码时自动放大\n***\n- [x] ZXing 生成可自定义颜色、带 logo 的二维码\n- [x] ZXing 生成一维码\n- [x] ZXing 扫描条码、二维码\n- [x] ZXing 识别图库中的条码、二维码图片\n***\n- [x] ZBar 扫描条码、二维码「已解决中文乱码问题」\n- [x] ZBar 识别图库中的条码、二维码图片\n\n## 常见问题\n#### 1.部分手机无法扫描出结果，扫描预览界面二维码被压缩\n\n使用的时候将 Toolbar 或者其他 View 盖在 ZBarView 或者 ZXingView 的上面，让 ZBarView 或者 ZXingView 填充屏幕宽高。[ZXing 布局文件参考](https://github.com/bingoogolapple/BGAQRCode-Android/blob/master/zxingdemo/src/main/res/layout/activity_test_scan.xml) [ZBar 布局文件参考](https://github.com/bingoogolapple/BGAQRCode-Android/blob/master/zbardemo/src/main/res/layout/activity_test_scan.xml)\n\n#### 2.出现黑屏\n\n在自己项目里集成时记得在 onDestroy 方法中调用 mQRCodeView.onDestroy()，在 onStop 方法中调用 mQRCodeView.stopCamera()，否则会出现黑屏。如果没执行前面提到的这两个方法出现黑屏的话，那你就只能加上前面提到的两个方法后，重启手机后重新运行了\n\n## 效果图与示例 apk\n\n\n\n\n\n\n\n| [点击下载 ZXingDemo.apk](http://fir.im/ZXingDemo)或扫描下面的二维码安装 | [点击下载
