资源介绍:

网上很多关于zxing的相关资源，但基本都是调用的camera或camerax进行集成的，由于摄像头原因，camera原生api又无法进行对焦，camerax在系统源码中又不是很方便导入到编译脚本，故使用了camera2进行集成。 关键代码调用: LuminanceSource source = new RGBLuminanceSource(width, height, data); BinaryBitmap bitmap1 = new BinaryBitmap(new HybridBinarizer(source)); Result qrCodeResult = null; MultiFormatReader multiFormatReader = new MultiFormatReader(); try { qrCodeResult = multiFormatReader.decode(bitmap1); } catch (NotFoundException e) { }
