ZXingView 可更新下

rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new GlobalHistogramBinarizer(source))); if (rawResult == null) { rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new HybridBinarizer(source))); if (rawResult != null) { BGAQRCodeUtil.d("GlobalHistogramBinarizer 没识别到，HybridBinarizer 能识别到"); } }

改成 rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new GlobalHistogramBinarizer(source))); if (rawResult == null) { rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new HybridBinarizer(source))); if (rawResult != null) { BGAQRCodeUtil.d("GlobalHistogramBinarizer 没识别到，HybridBinarizer 能识别到"); }else{ rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new HybridBinarizer(source.invert()))); } }

rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new HybridBinarizer(source.invert())));加上这个可以识别彩色二维码

识别的那段代码有问题！作者有空改下吧！ private Result getRawResult(Binarizer binarizer){ Result rawResult; try { rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(binarizer)); }catch (Exception e){ rawResult = null; } return rawResult; }

rawResult = getRawResult(new GlobalHistogramBinarizer(source)); if (rawResult == null) { rawResult = getRawResult(new HybridBinarizer(source)); if (rawResult != null) { BGAQRCodeUtil.d("GlobalHistogramBinarizer 没识别到，HybridBinarizer 能识别到"); }else { rawResult = getRawResult(new HybridBinarizer(source.invert())); } }

---

rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new GlobalHistogramBinarizer(source))); 这段代码会报NotFoundException 异常 rawResult = mMultiFormatReader.decodeWithState(new BinaryBitmap(new HybridBinarizer(source))); 这段就不生效了改完识别率会提高，还能识别彩色的二维码！

是的，下载源码 按照您这样改就可以，效率还变高了
