Android扫一扫Zxing之基础依赖

Android扫一扫Zxing

这个是最基础的Zxing的依赖扫一扫，Zxing设置的扫描是横屏，之后的文章会写篇自定义的Zxing扫一扫

一、在根目录的build.gradle中添加依赖

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

二、在主项目的build.gradle中添加依赖，并同步gradle

compile 'com.google.zxing:core:3.0.1' 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'

三、在清单文件中添加权限

<uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.FLASHLIGHT" /> 注："android.permission.CAMERA"在Android6.0以上系统中要手动获取参考：Android6.0以上系统获取权限

四、跳转到扫描界面

//跳转到扫描界面 IntentIntegrator intentIntegrator = new IntentIntegrator(MainActivity.this); intentIntegrator.initiateScan();

五、重写回调，解码扫描结果

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data); if (scanResult != null) { String result = scanResult.getContents(); Log.e("LKing","扫描结果："+result); } }
