In MainActivity.java a function called HandleClick processes the pressed button (using the button id to determine which mode to call the scanner).

The two TextViews will display the type of barcode scanned and the data it contains. Add another Large Text and set the layout:width and layout:height to fill_parent and the id to tvResult: Add a Large Text below the buttons setting the background property to black, the textColor property to white and the id to tvStatus. Set their ids to butQR, butProd and butOther. Drop three Button widgets on to the screen and set their text to QR CODE, PRODUCT and OTHER. In Studio delete the TextView on the starting activity_main.xml layout. Here, for the tutorial App, the Application name is set to Scan Barcode and an Empty Activity is used.

Google has a free scanning App that can be accessed from another App, using an Intent. Scanning barcodes and Quick Response (QR) codes is a good example. One of the great features of Android is how easy it is to tap into existing functionality. Here is this website's address as a QR Code. Adding support for barcodes and QR codes in an App opens up new interface, communication and feature possibilities. QR codes are useful for communicating web addresses and contact details. They are particularly good for stock control hence the universal use on packaging and for logistics. Capture data with unmatched abilities developed and continuously refined by a partner with more than 50 years of field-proven innovation. Zebra anticipates every challenge so you can scan anything, anywhere, no matter what. The result of scan will be passed to this function.Use the ZXing Barcode Scanner in an Android Appīarcodes and Quick Response (QR) codes are useful for storing short sequences of data that can be recognised by a variety of machines and devices. The ability to scan dirty, damaged barcodes, survive harsh work environments and streamline day-to-day management. Scanner requires “onActivityResult” function defined in the calling Activity. This function will use Intent and launch the scanner. tCameraId(0) // Use a specific camera of the device tPrompt(this.getString(R.string.scan_bar_code)) tDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES) IntentIntegrator integrator = new IntentIntegrator(this)

In the HomeActivity.java create a function named “scanNow” this function is attached to the onClick event of the scan button in our layout. This layout has a simple “scan” button and two text views to display scanned result.

I have a simple layout which I have used in my recent posts, we will re-use it again. Step 2 : Create your HomeActivity and layout Android phones are getting the latest OS releases a lot quicker now days so I have decided not to cover legacy phones. This code only works for API version 23 and over. We are modifying the application adle file located in your “app” folderĬompile fileTree(dir: 'libs', include: )Ĭompile 'com.journeyapps:zxing-android-embedded:3.4.0'Ĭompile ':appcompat-v7:23.1.0' // Version 23+ is required Step 1 : Add library as dependencyĬreate a new project in android studio and add the following code into adle file. This implementation is available as a dependency via jcentre and supports Intents, which makes it a perfect fit for our use case. This implementation is not affiliated by the official Zxing guys but the developer did all the changes which we needed for the scanner to open in vertical mode. Zxing library is open source and we can modify the layouts and include it into our project.Īfter some research and looking into the code on github I found another implementation of Zxing Library. There is no simple way to change that and we have to edit the library files. The default implementation of the Zxing library has scanner fixed to “Landscape Mode”. First, we need to build the Gradle codes and Android Hive. Now, we are going to include the Barcode Reader library to work correctly. In this post I will explain these points in detail. Steps to follow Add the below code in 'build Gradle' to add library files to our Barcode reader.
