问题 I'm developing a mobile application on Xamarin Forms for UWP, Android and IOS on Visual Studio. I'm currently testing the app on my computer(Windows 10) and my phone (also Windows 10). I'm using Zxing MobileBarcodeScanner to scan multiple barcodes. When i press the back button i call the MobileBarcodeScanner.Cancel(). The only thing that it does is to close the camera. It doesn't depose the MobileBarcodeScanner's UI and i didn't found any solution for that. Can anyone help me or suggest a

问题 I am using zxing in a fragment of viewpager tab. I can call zxing with Intent and read the QR code but I can't get result to a edittext. This is where i create tab in FragmentPagerAdapter: @Override public Fragment getItem(int i) { switch (i) { case 0: return new Tab1(); case 1: return new Tab2(); default: return new EmptyTab(); } } And my Tab1 class: public class Tab1 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState

问题 Okay, So I am developing an in house barcode scanner for my company to use when we move computers and equipment. I am currently almost through setting up the Zxing Barcode Scanner Via Intent after some trial and error. Here is what I'm trying to do. Next to three EditText fields I have Three ImageButtons that when clicked, implement the BarcodeScanner , once scanned returns the value and inputs the value into the EditText field. I was able to do it successfully using one "listener"

问题 Using ZXing (on Android), if you initiate a PDF417 barcode scan like this... List<String> oDesiredFormats = Arrays.asList("PDF_417".split(",")); IntentIntegrator integrator = new IntentIntegrator(this); integrator.initiateScan(oDesiredFormats); ... and you initiate an "all codes" (except PDF417 and maybe a few others) barcode scan like this... IntentIntegrator integrator = new IntentIntegrator(this); integrator.initiateScan(); ... then how do you initiate a single barcode scan that will

While the app processes captured screen frames the app receives memory warnings and is then shut down. I have removed the call to Zxing to track down where the memory issue stems from and can reproduce the issue with just capturing the screen image in a loop. Here is the code: using System; using System.Drawing; using System.Collections.Generic; using System.Threading; using

问题 I converted the jar file into .net dll file using IKVM. Now i am trying to consume it in my .net app, but it seems that the qrcodereader.decode requires BinaryBitmap which further requires Luminance as parameter. Please guide me in this situation since i couldn't find the right classes that implements the abstract classes. 回答1: Luminance sources are platform specific. You can find examples in the android, java2se, and iphone directories. I don't know if there are any luminance sources in the

问题 UPDATE 2 I posted an answer that fixes my original problem. See that for more information. UPDATE FYI for anyone wondering, in the end I found this: http://github.com/commonsguy/zxingdemo/tree/master Exactly what I needed to get it rolling was a simple demo that worked! Also, thanks to Sean for pointing me in the right direction for my googling. I am currently trying to build a simple android app that can scan in a barcode. I have looked through multiple tutorials, tried everything to a T,
