ZXing 3.6.0 in portrait mode?

Question

I use XZing 3.6.0 to scan QR codes within my Android app.

MainActivity.java

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

import com.google.zxing.Result;
import com.google.zxing.integration.android.IntentIntegrator;
import com.google.zxing.integration.android.IntentResult;

public class MainActivity extends AppCompatActivity  {

    Button btnScan;
    TextView tv;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnScan = (Button) findViewById(R.id.btn_scan);
        tv = (TextView) findViewById(R.id.tv);

        btnScan.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View view) {
                IntentIntegrator scanIntegrator = new IntentIntegrator(MainActivity.this);
                scanIntegrator.setOrientationLocked(false);
                scanIntegrator.initiateScan();
            }
        });
    }

    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
        if (scanningResult != null) {
            String scanContent = scanningResult.getContents();
            tv.setText(scanContent);
        }
        else {
            Toast toast = Toast.makeText(getApplicationContext(),
                    "No scan data received!", Toast.LENGTH_SHORT);
            toast.show();
        }
    }

}

AndroidManifest.xml

 <activity
        android:name=".MainActivity"
        android:screenOrientation="portrait"
        >

It works... except the camera is shown in landscape mode. How to change that to portrait mode?

Answer 1

Add this to your Manifest File :

<activity
   android:name="com.journeyapps.barcodescanner.CaptureActivity"
   android:screenOrientation="portrait"
   tools:replace="android:screenOrientation"
   android:stateNotNeeded="true"/>
