1、app目录下build.gradle文件添加依赖
dependencies {
implementation 'com.journeyapps:zxing-android-embedded:3.5.0'
}
2、activity添加扫描代码
IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);
// 设置要扫描的条码类型，ONE_D_CODE_TYPES：一维码，QR_CODE_TYPES-二维码
integrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);
integrator.setCaptureActivity(ScanActivity.class);
integrator.setPrompt("请扫描二维码"); //底部的提示文字，设为""可以置空
integrator.setCameraId(0); //前置或者后置摄像头
integrator.setBeepEnabled(false); //扫描成功的「哔哔」声，默认开启
integrator.setBarcodeImageEnabled(true);//是否保留扫码成功时候的截图
integrator.initiateScan();
3、扫描后返回结果代码
/**
*扫描成功结果处理
* @param requestCode
* @param resultCode
* @param data
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (scanResult != null) {
String result = scanResult.getContents();
}
}
4、AndroidManifest.xml添加相机权限
<uses-permission android:name="android.permission.CAMERA" />
另外、支持竖屏扫描
1、新建activity添加实现代码
/**
* 竖屏扫描
*/
public class ScanActivity extends CaptureActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
