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();
}
}
