Integrate the default QR Code scan page

1. Perform the compile operation in the module's Build.gradle

Compile ' cn.yipianfengye.android:zxing-library:2.2 '

2. Perform initialization in demo application

@Override      Public void onCreate () {        super. OnCreate ();        Zxinglibrary.initdisplayopinion (this);    }

3. Perform open scan QR code interface operation

  New Intent (mainactivity.  this, captureactivity. class );  Startactivityforresult (Intent, Request_code);
The request_code here is our definition of the INT type constant

4. Receive the scan results in the activity's Onactivityresult method

/*** processing QR code scan results*/        if(Requestcode = =Request_code) {            //processing Scan results (displayed on the interface)            if(NULL!=data) {Bundle Bundle=Data.getextras (); if(Bundle = =NULL) {                    return; }                if(Bundle.getint (codeutils.result_type) = =codeutils.result_success) {String result=bundle.getstring (codeutils.result_string); Toast.maketext ( This, "Parse Result:" +result, Toast.length_long). Show (); } Else if(Bundle.getint (codeutils.result_type) = =codeutils.result_failed) {Toast.maketext (mainactivity). This, "Parsing the QR code failed", Toast.length_long). Show (); }            }        }
