使用zxing解析相冊(cè)圖片是發(fā)現(xiàn)只能解析黑白的圖片捍壤，后面又試了微信和qq都能成功解析了彩色的圖片室埋，網(wǎng)上找了半天沒找到辦法辖试，最后在github上找到了解決方法

下面的方法只能解析黑白的二維碼

    /**
     * 解析二維碼圖片
     */
    public static String decodeQRCode(Bitmap srcBitmap) {
        MultiFormatReader multiFormatReader = new MultiFormatReader();
        // 解碼的參數(shù)
        Hashtable<DecodeHintType, Object> hints = new Hashtable<>(2);
        // 可以解析的編碼類型
        Vector<BarcodeFormat> decodeFormats = new Vector<>();
        if (decodeFormats == null || decodeFormats.isEmpty()) {
            // 設(shè)置可掃描的類型
            decodeFormats.addAll(DecodeFormatManager.QR_CODE_FORMATS);
        }
        hints.put(DecodeHintType.POSSIBLE_FORMATS, decodeFormats);
        hints.put(DecodeHintType.CHARACTER_SET, "UTF8");
        multiFormatReader.setHints(hints);
        Result result = null;
        BitmapLuminanceSource source = new BitmapLuminanceSource(srcBitmap);
        BinaryBitmap binaryBitmap = new BinaryBitmap(new HybridBinarizer(source));
        try {
            result = multiFormatReader.decodeWithState(binaryBitmap);
        } catch (Exception e) {
            e.printStackTrace();
        }
        if (result != null) {
            return result.getText();
        }
        return null;
    }

支持彩色二維碼解析

    /**
     * 解析圖片
     *
     * @param srcBitmap
     * @return
     */
    public static String decodeQRCode(Bitmap srcBitmap) {
        // 解碼的參數(shù)
        Hashtable<DecodeHintType, Object> hints = new Hashtable<>(2);
        // 可以解析的編碼類型
        Vector<BarcodeFormat> decodeFormats = new Vector<>();
        if (decodeFormats.isEmpty()) {
            decodeFormats.addAll(DecodeFormatManager.QR_CODE_FORMATS);
        }
        hints.put(DecodeHintType.POSSIBLE_FORMATS, decodeFormats);
        hints.put(DecodeHintType.CHARACTER_SET, "UTF-8");
        Result result = null;
        int width = srcBitmap.getWidth();
        int height = srcBitmap.getHeight();
        int[] pixels = new int[width * height];
        srcBitmap.getPixels(pixels, 0, width, 0, 0, width, height);
        //新建一個(gè)RGBLuminanceSource對(duì)象
        RGBLuminanceSource source = new RGBLuminanceSource(width, height, pixels);
        //將圖片轉(zhuǎn)換成二進(jìn)制圖片
        BinaryBitmap binaryBitmap = new BinaryBitmap(new GlobalHistogramBinarizer(source));
        QRCodeReader reader = new QRCodeReader();//初始化解析對(duì)象
        try {
            result = reader.decode(binaryBitmap, hints);//開始解析
        } catch (NotFoundException | ChecksumException | FormatException e) {
            e.printStackTrace();
        }
        if (result != null) {
            return result.getText();
        }
        return null;
    }
