here is an example code for integrating ZXing barcode scanner in Android Studio:

Add ZXing dependency to your app's build.gradle file:

build.gradle

dependencies {
    implementation 'com.google.zxing:core:3.4.1'
}

Create a new activity called ScannerActivity.java:

ScannerActivity.java

import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;

import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;

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

public class ScannerActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        IntentIntegrator integrator = new IntentIntegrator(this);
        integrator.setPrompt("Scan a barcode or QR code");
        integrator.setOrientationLocked(false);
        integrator.initiateScan();
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable 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();
            }
            finish();
        } else {
            super.onActivityResult(requestCode, resultCode, data);
        }
    }
}

In your app's AndroidManifest.xml, add the following permissions and activity:

AndroidManifest.xml

<uses-permission android:name="android.permission.CAMERA" />

<application
    ...
    <activity android:name=".ScannerActivity"
        android:screenOrientation="portrait"/>
    ...
</application>

In your app's MainActivity.java, add the following code to start the scanner activity when a button is clicked:

MainActivity.java

 Button scanButton = findViewById(R.id.scan_button);
        scanButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(MainActivity.this, ScannerActivity.class);
                startActivity(intent);
            }
        });

Finally, create a layout file called activity_main.xml with a button to start the scanner activity:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:id="@+id/scan_button"
        android:text="Scan Barcode"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"/>

</LinearLayout>

That's it! Run your app and click the "Scan Barcode" button to start scanning.
