如何通过Android NFC传输纯文本？

NfcAdapter nfcAdapter = NfcAdapter.getDefaultAdapter(this);

<uses-permission android:name="android.permission.NFC" />

NdefMessage ndefMessage = new NdefMessage(
    new NdefRecord[] { NdefRecord.createTextRecord(null, "Hello, NFC!") });

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
IntentFilter ndefIntentFilter = new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);
try {
    ndefIntentFilter.addDataType("text/plain");
} catch (IntentFilter.MalformedMimeTypeException e) {
    e.printStackTrace();
}
IntentFilter[] intentFiltersArray = new IntentFilter[] { ndefIntentFilter };
String[][] techListsArray = new String[][] { new String[] { NfcF.class.getName() } };
nfcAdapter.enableForegroundDispatch(this, pendingIntent, intentFiltersArray, techListsArray);

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(intent.getAction())) {
        Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
        Ndef ndef = Ndef.get(tag);
        if (ndef != null) {
            try {
                ndef.connect();
                ndef.writeNdefMessage(ndefMessage);
                ndef.close();
                Toast.makeText(this, "NFC传输成功！", Toast.LENGTH_SHORT).show();
            } catch (IOException | FormatException e) {
                e.printStackTrace();
            }
        }
    }
}
