Android สอบถามเรื่อง NFC การอ่าน Tag ครับ อยากให้ผลลัพธืที่แสดงออกมาเป็นแค่ข้อความใน tag

public class TagDispatch extends Activity {
    private TextView mTextView;
    private NfcAdapter mNfcAdapter;
    private PendingIntent mPendingIntent;
    private IntentFilter[] mIntentFilters;
    private String[][] mNFCTechLists;

    @Override
    public void onCreate(Bundle savedState) {
        super.onCreate(savedState);

        setContentView(R.layout.main);
        mTextView = (TextView)findViewById(R.id.tv);
        mNfcAdapter = NfcAdapter.getDefaultAdapter(this);

        if (mNfcAdapter != null) {
            mTextView.setText("Read an NFC tag");
        } else {
            mTextView.setText("This phone is not NFC enabled.");
        }

        // create an intent with tag data and deliver to this activity
        mPendingIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);

        // set an intent filter for all MIME data
        IntentFilter ndefIntent = new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);
        try {
            ndefIntent.addDataType("*/*");
            mIntentFilters = new IntentFilter[] { ndefIntent };
        } catch (Exception e) {
            Log.e("TagDispatch", e.toString());
        }

        mNFCTechLists = new String[][] { new String[] { NfcF.class.getName() } };
    }

    @Override
    public void onNewIntent(Intent intent) {
        String action = intent.getAction();
        Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);

        String s = action + "\n\n" + tag.toString();

        // parse through all NDEF messages and their records and pick text type only
        Parcelable[] data = intent.getParcelableArrayExtra(NfcAdapter.EXTRA_NDEF_MESSAGES);
        if (data != null) {
            try {
                for (int i = 0; i < data.length; i++) {
                    NdefRecord [] recs = ((NdefMessage)data).getRecords();
                    for (int j = 0; j < recs.length; j++) {
                        if (recs[j].getTnf() == NdefRecord.TNF_WELL_KNOWN &&
                            Arrays.equals(recs[j].getType(), NdefRecord.RTD_TEXT)) {
                            byte[] payload = recs[j].getPayload();
                            String textEncoding = ((payload[0] & 0200) == 0) ? "UTF-8" : "UTF-16";
                            int langCodeLen = payload[0] & 0077;

                            s += ("\n\nNdefMessage[" + i + "], NdefRecord[" + j + "]:\n\"" +
                                 new String(payload, langCodeLen + 1, payload.length - langCodeLen - 1,
                                 textEncoding) + "\"");
                        }
                    }
                }
            } catch (Exception e) {
                Log.e("TagDispatch", e.toString());
            }
        }

        mTextView.setText(s);
    }

    @Override
    public void onResume() {
        super.onResume();

        if (mNfcAdapter != null)
            mNfcAdapter.enableForegroundDispatch(this, mPendingIntent, mIntentFilters, mNFCTechLists);
    }

    @Override
    public void onPause() {
        super.onPause();

        if (mNfcAdapter != null)
            mNfcAdapter.disableForegroundDispatch(this);
    }
