Android 从扫描二维码的结果中获取并重定向URL

我是一个新的机器人。 我有一个简单的二维码扫描应用程序。但它只显示结果

我希望它从这个结果中获取url并重定向到它

这是我的密码

MainActivity.java

package app.num.barcodescannerproject;

import android.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

import com.google.zxing.Result;
import me.dm7.barcodescanner.zxing.ZXingScannerView;

public class MainActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler {
private ZXingScannerView mScannerView;

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

}

public void QrScanner(View view){


    mScannerView = new ZXingScannerView(this);   // Programmatically initialize the scanner view
    setContentView(mScannerView);

    mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
    mScannerView.startCamera();         // Start camera

}

@Override
public void onPause() {
    super.onPause();
    mScannerView.stopCamera();           
}

@Override
public void handleResult(Result rawResult) {
    // Do something with the result here

    Log.e("handler", rawResult.getText());
    Log.e("handler", rawResult.getBarcodeFormat().toString());

    // show the scanner result into dialog box.
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Result");
    builder.setMessage(rawResult.getText());
    AlertDialog alert1 = builder.create();
    alert1.show();


   mScannerView.resumeCameraPreview(this);
}
}
