public Button.OnClickListener mScan = new Button.OnClickListener() { 
    public void onClick(View v) { 
        Intent intent = new Intent("com.google.zxing.client.android.SCAN"); 
        intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); 
        startActivityForResult(intent, 0); 
    } 
}; 
 
public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
    if (requestCode == 0) { 
        if (resultCode == RESULT_OK) { 
            String contents = intent.getStringExtra("SCAN_RESULT"); 
            String format = intent.getStringExtra("SCAN_RESULT_FORMAT"); 
            // Handle successful scan 
        } else if (resultCode == RESULT_CANCELED) { 
            // Handle cancel 
        } 
    } 
}
