I am using zxing 2.0. I'm trying to create a Bar code, but instead it's creating a QR code.

Encoding and decoding random byte array with zxing

问题 I'm trying to transfer a byte array with QR code, so for testing, I decided to generate a random byte array, encode it as QR code, then decode it. I used ISO-8859-1 to convert byte array to string s.t it does not lose data while transmission: For encoder side: byte []buffer = new byte[11]; com.google.zxing.Writer writer = new QRCodeWriter(); Random randomGenerator = new Random(); for(int i=0;i<=10;i++){ buffer[i]=(byte) randomGenerator.nextInt(254); } // Log.i("time1","original: "+Arrays

问题 I'm having trouble generating a QR code on mango 7.1 with ZXing 2.0. It should be pretty straight forward, but it's not working. The code: QRCodeWriter writer = new QRCodeWriter(); var bMatrix = writer.encode("Hey dude, QR FTW!", BarcodeFormat.QR_CODE, 25, 25); var asBitmap = bMatrix.ToBitmap(); image1.Source = asBitmap; image1 comes from the xaml. bMatrix seems to contain the data that I need, but image1 never shows a thing. 回答1: So I managed to do a workaround. I'm not sure if my original

How to call scanned barcode history from zxing

问题 I am scanning barcodes using Zxing in my application i have a button called History onclick it should display scanned barcode history i dont know how to call history from zxing. 回答1: If by Zxing, you mean you are using the library (not the zxing client app) to scan QR codes then you will have to implement the history related functionality on your own. Basically save items in the database base each time you have successfully scanned something. Take a look at the implementation of history

问题 I have followed the following answer to do this. https://stackoverflow.com/a/16252917/2747591 But I am not getting what i want to do. The image captured by camera is rotated by 90 degree while i am trying to scan. Like if you are clicking a photo of a person using the camera, then in my phone screen it is showing the preview rotated by 90 degree. But that is not what i want as it is making bar code scanning difficult to use. I want preview as it should be. Any ideas? Here are my changes in

问题 I am trying to create a simple Android app, which would display a QR-coded image - by using zxing library.
