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
