目录：zxing->encoding->EncodingHandler类 中修改 createQRCode方法
代码语言：javascript复制 private static final int BLACK = 0xff000000;
private static final int WHITE = 0xffffffff;
public static Bitmap createQRCode(String str,int widthAndHeight) throws WriterException {
String contentsToEncode = str;
if (contentsToEncode == null) {
return null;
}
Map<EncodeHintType, Object> hints = new EnumMap<>(EncodeHintType.class);
//hints.put(EncodeHintType.CHARACTER_SET, encoding);
hints.put(EncodeHintType.MARGIN, 0); /* default = 4 */
MultiFormatWriter writer = new MultiFormatWriter();
BitMatrix result;
try {
result = writer.encode(contentsToEncode, BarcodeFormat.QR_CODE , widthAndHeight, widthAndHeight, hints);
} catch (Exception e) {
// Unsupported format
e.printStackTrace();
return null;
}
int width = result.getWidth();
int height = result.getHeight();
int[] pixels = new int[width * height];
for (int y = 0; y < height; y ) {
int offset = y * width;
for (int x = 0; x < width; x ) {
pixels[offset x] = result.get(x, y) ? BLACK : Color.WHITE;
}
}
Bitmap bitmap = Bitmap.createBitmap(width, height,
Bitmap.Config.ARGB_8888);
bitmap.setPixels(pixels, 0, width, 0, 0, width, height);
return bitmap;
}
