开启的二维码扫描是横屏的哦！亲！

首先，在build.gradle中添加以下依赖：

repositories {        mavenCentral()           maven {               url "http://dl.bintray.com/journeyapps/maven"              }        }

compile 'com.journeyapps:zxing-android-embedded:2.0.1@aar'    compile 'com.journeyapps:zxing-android-legacy:2.0.1@aar'    compile 'com.journeyapps:zxing-android-integration:2.0.1@aar'    compile 'com.google.zxing:core:3.0.1'

添加权限：

<uses-permission android:name="android.permission.INTERNET"/>    <uses-permission android:name="android.permission.CAMERA"/>    <uses-permission android:name="android.permission.VIBRATE"/>

点击事件：

@Override            public void onClick(View v) {                //扫描操作                IntentIntegrator integrator = new IntentIntegrator(getActivity());                integrator.initiateScan();            }

@Override    public void onActivityResult(int requestCode, int resultCode, Intent data) {        IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);        if (scanResult != null) {            String result = scanResult.getContents();            Log.d("code", result);            Toast.makeText(getActivity(),result, Toast.LENGTH_LONG).show();        }    }
