Easiest way to integrate ZXing for barcode or Qr scanning.

For Full Reference : Scan Barcode ZXing Android

Add in dependencies

compile 'me.dm7.barcodescanner:zxing:1.9' 

ScanActivity

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import com.google.zxing.Result;

import me.dm7.barcodescanner.zxing.ZXingScannerView;

public class ScanActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler{

    private ZXingScannerView mScannerView;

    @Override
    public void onCreate(Bundle state) {
        super.onCreate(state);
        mScannerView = new ZXingScannerView(this);   // Programmatically initialize the scanner view
        setContentView(mScannerView);                // Set the scanner view as the content view
    }

    @Override
    public void onResume() {
        super.onResume();
        mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
        mScannerView.startCamera();          // Start camera on resume
    }

    @Override
    public void onPause() {
        super.onPause();
        mScannerView.stopCamera();           // Stop camera on pause
    }

    @Override
    public void handleResult(Result rawResult) {
        // Do something with the result here
       // Log.v("tag", rawResult.getText()); // Prints scan results
       // Log.v("tag", rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)

        MainActivity.tvresult.setText(rawResult.getText());
        onBackPressed();

        // If you would like to resume scanning, call this method below:
        //mScannerView.resumeCameraPreview(this);
    }
}
