Adding aar dependency with Gradle

From version 3.6.0, only Android SDK 19+ is supported by default.

Add the following to your build.gradle file:

implementation 'com.journeyapps:zxing-android-embedded:3.6.0'

 

Hardware Acceleration

Hardware accelation is required since TextureView is used.

Make sure it is enabled in your manifest file:

<application android:hardwareAccelerated="true" ... >

 

Add this code to Activitiy 

Customize options:

onCreate(){ // onCreate에 넣거나 버튼클릭이벤트 넣거나
  IntentIntegrator integrator = new IntentIntegrator(this);
  integrator.setDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES);
  integrator.setPrompt("Scan a barcode");
  integrator.setCameraId(0);  // Use a specific camera of the device
  integrator.setBeepEnabled(false);
  integrator.setBarcodeImageEnabled(true);
  integrator.initiateScan();
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
    if(result != null) {
        if(result.getContents() == null) {
            Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
        }
    } else {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

위의 방법은 세로모드만 인식된다.

가로모드로 바코드를 찍고싶다면.

1.자바 클래스 추가

import com.journeyapps.barcodescanner.CaptureActivity;

public class AnyOritationCaptureActivity extends CaptureActivity {
}

2.Manifests 추가

<activity android:name=".JavaClass.AnyOritationCaptureActivity"
                  android:screenOrientation="fullSensor"
                  android:stateNotNeeded="true"
                  android:theme="@style/zxing_CaptureTheme"
                  android:windowSoftInputMode="stateAlwaysHidden"/>

3. IntentIntegrator 에

integrator.setCaptureActivity(AnyOritationCaptureActivity.class);

추가

 

애플은 사랑입니다!
