Step 3

Here your layout file code:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
        
        <com.gpfreetech.awesomescanner.ui.ScannerView
            android:id="@+id/scanner_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight=".3"
            app:autoFocusButtonColor="@android:color/white"
            app:autoFocusButtonVisible="true"
            app:flashButtonColor="@android:color/white"
            app:flashButtonVisible="true"
            app:frameAspectRatioHeight="1"
            app:frameAspectRatioWidth="1"
            app:frameColor="@android:color/white"
            app:frameCornersRadius="0dp"
            app:frameCornersSize="50dp"
            app:frameSize="0.70"
            app:frameThickness="5dp"
            app:maskColor="#77000000"
            app:isAnimated="true"/>
</FrameLayout>

Step 4

And add following code to your activity:

Java

public class MainActivity extends AppCompatActivity {

    private GpCodeScanner mCodeScanner;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        ScannerView scannerView = findViewById(R.id.scanner_view);
        
        mCodeScanner = new GpCodeScanner(this, scannerView);
        
        mCodeScanner.setDecodeCallback(new DecodeCallback() {
            @Override
            public void onDecoded(@NonNull final Result result) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(getApplicationContext(), result.getText(), Toast.LENGTH_SHORT).show();
                        txtScanText.setText("" + result.getText());
                    }
                });
            }
        });

        scannerView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mCodeScanner.startPreview();
            }
        });
    }

    @Override
    protected void onResume() {
        super.onResume();
        if(mCodeScanner!=null) {
            mCodeScanner.startPreview();
        }
    }

    @Override
    protected void onPause() {
        if(mCodeScanner!=null) {
            mCodeScanner.releaseResources();
        }
        super.onPause();
    }
}

Additional Methods

Change / set BACK or FRONT Camera
