zxing

Simple use of ZXing in Android, androidzxing ZXing is a widely used QR code scanning library with fast scanning speed and high recognition rate. There are a lot of simplified and useful information about zxing on the Internet. Here is a summary: 1. Rewrite the ViewfinderView class under the com. mining. app. zxing. v

Two-dimensional code:It is a black-and-white graph which is distributed in the plane (two-dimensional direction) by a certain geometry to record the data symbol information;The concept of 0-and 1-bit streams, which compose the logic basis of the computer, is used to represent the literal numerical information by using several geometric shapes corresponding to the binary system, and the automatic reading is realized by the image input device or photoelectric scanning device to realize automatic i

http://code.google.com/p/zxing/ Zxing (pronounced "zebra crossing") is a open-source, multi-format 1d/2d barcode image processing library implemented in Java, with ports to the other languages. We are on using the built-in camera on mobile phones to scan and decode on the barcodes, device without G with a server. However the project can be used to encode and decode barcodes on desktops and servers as. The

This article describes two ways for Android studio to import zxing, for informational purposes only. 1. Direct Complie Import 1.1 Build.gradle Direct Complie of items that need to be scanned using zxing for two-dimensional code 1.2 Call: 1.3 Callback Result: Here you can see the scanning two-dimensional code interface and get the scan results, but this direct compile method, can not change the s

Java uses Zxing to generate a QR code. Zxing is a parsing tool provided by Google for bar code (one-dimensional code and two-dimensional code). It provides a method for generating and parsing QR codes, now I will briefly introduce the use of Java to use Zxing to generate and parse the QR code 1, the generation of the QR code 1.1 to add the

Android: Use ZXing to generate two-dimensional codes (Logo images can be added) and androidzxing ZXing is an open-source library of Google that can be used to generate and scan QR codes. This article introduces the first part. First: ZXing-related files official: https://github.com/zxing/

Recently I have been studying QR code recognition and used the zxing open source code, but the GBK type is always garbled. After two days of hard work, I finally solved the problem today. Remember ,. I was developed on the basis of the Zxing-1.6, because zxing1.6 to the vertical screen to support better. First, we need to build the environment for compiling core. jar, which I will not talk about. If not, yo

Practical Android skills-Maven compilation of the open-source QR code scanning project zxing Having your own mobile phone software toolbox is very meaningful. For the current domestic Android ecosystem, Chaos cannot be disrupted. Because we can't log on to the App store on the official website, we have to download the software from various Chinese software markets. Due to the ineffective supervision of these markets, there are all kinds of software. T

Learn QR code scanning, first download zip,:https://github.com/zxing/zxing/archive/master.zipAfter the download is complete, the contents of the compressed package are as follows:In order to successfully run the Zxing demo on the Android platform,Android/android-core/android-integration/core/Four folders extracted, Androidtest can choose to extract outOne Android

Zxing is the code for bar code scanning and formation, including the source code for Android, iPhone, and C ++. This time I transplanted the ZIP file of version 1.6 downloaded in zxing. I can also search for the QT code of qqrdecoder on the Internet, but it contains the old version and can only recognize the QR code, that is, a QR code. And there is not much interference and clear picture under the photo.

QR code in the application of more and more, so that is to find the relevant information to write a two-dimensional code scanning and generation of two-dimensional code of the demo.This demo uses a third-party zxing library. GitHub's address:ZxingReferences in Androidstudio:File---New---Import module imports zxing third-party libraries and then selects items by F4,Click the plus sign to select File dependen

Recently I have been studying QR code recognition and used the Zxing open source code, but the GBK type is always garbled. After two days of hard work, I finally solved the problem today. Remember ,.

Zxing is a Google-provided on the barcode (one-dimensional code, two-dimensional code) analytical tools, provides a two-dimensional code generation and resolution method, now I briefly introduce the use of Java to generate and parse two-dimensional code zxing 1, two-dimensional code generation 1.1 Add the Zxing-core.jar package to the classpath. 1.2 Two-dimens

This simple problem has plagued me for nearly two hours, mainly because I did not find a demo in the official document. I can only use the search engine to check the programs written by other programmers, however, it was found that there were pitfalls everywhere. I read four or five examples. None of them were able to run normally, and all of them reported errors. After more than an hour of trying, I finally got it done. Let's just move on to the code. The second step is to create An aspx file.

In our zxing framework for the two-dimensional code scanning, we will find that the mobile phone with the resolution of the increase, the scan box will be smaller, in 1920*1280 and 1280*720 is relatively normal, but Samsung's several mobile phones note4,5,s6, and other mobile phone resolution of up to 2560 *1440, even some mobile phones up to 3660 of the bar can't remember.When these phones scan, pop-up scan activity middle Surfaceview Scan window Sma

Zxing is currently used in a relatively wide range of two-dimensional code scanning library, scanning fast, high recognition rate, there are many online on the simplification and use of zxing, here is a summary:1, rewrite the Com.mining.app.zxing.view package below the Viewfinderview class to implement their own scan box style. 2. modify the size of the scan box in CameramanagerThis article is well written,

Zxing source code analysis (1) camera, zxingcamera First, let's download the source code of zxing. There are a lot of resources on the Internet. I downloaded 2.3 of them. I have to say that the package provided by Google contains a wide range of functions.After I decompress the downloaded package, find the android folder and import it to ecplise. Let's analyze the architecture 1 and book. If the query resul

After ZXing, one-dimensional code, two-dimensional code, and other codes are scanned separately. I have never touched on the QR code before. I recently encountered a problem: how can I determine whether the QR code is scanned by a QR code or by a QR code? after hard work for one afternoon, I can search online materials, There are two ways to solve this problem (the second method is recommended ): 1. Modify the source code (as mentioned later)2. Determ
