Create a QR Code and show it in ImageView

I am creating an app which will be able to scan QR code and create QR code. The scanning part is done and its working fine. But when I try to create the QR code and show it in an ImageView the QR code created is not containing correct text. I am using ZXING library.

Hashtable<EncodeHintType, ErrorCorrectionLevel> hintMap = new Hashtable<>();
hintMap.put(EncodeHintType.ERROR_CORRECTION, ErrorCorrectionLevel.L);

QRCodeWriter qrCodeEncoder = new QRCodeWriter();
BitMatrix bitMatrix = qrCodeEncoder.encode(myText, BarcodeFormat.QR_CODE,
        200, 200, hintMap);

height = bitMatrix.getHeight();
width = bitMatrix.getWidth();

final Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);

for (x = 0; x < width; x++){
    bmp.setPixel(x, y, bitMatrix.get(x,y) ? Color.BLACK : Color.WHITE);
}

ImageView myImage = (ImageView) findViewById(R.id.qr_code);
myImage.setImageBitmap(bmp);
