Prototype

public NdefRecord[] getRecords() 

Source Link

Document

Get the NDEF Records inside this NDEF Message.

An NdefMessage always has one or more NDEF Records: so the following code to retrieve the first record is always safe (no need to check for null or array length >= 1):

 NdefRecord firstRecord = ndefMessage.getRecords()[0]; 

Usage

From source file:Main.java

public static String getNFCString(Parcelable[] rawMessages) {
    if (rawMessages != null && rawMessages.length == 1) {
        NdefMessage message = (NdefMessage) rawMessages[0];
        NdefRecord[] records = message.getRecords();
        if (records.length == 1) {
            byte[] payload = records[0].getPayload();

            //convert byte array to string, throw out first 3 characters (see http://stackoverflow.com/questions/7917567/strange-character-on-android-ndef-record-payload)
            return new String(payload).substring(3);
        }//from  w ww  . jav  a2s  .com
    }

    return null;
}

From source file:Main.java

public static boolean areMessagesEqual(NdefMessage message, NdefMessage otherMessage) {
    return message != null && otherMessage != null
            && areRecordArraysEqual(message.getRecords(), otherMessage.getRecords());
}

From source file:Main.java

    if (message == null) {
        return null;
    }//from w  w w  . j a  v  a 2s .c  o  m

    List<JSONObject> list = new ArrayList<JSONObject>();

    for (NdefRecord ndefRecord : message.getRecords()) {
        list.add(recordToJSON(ndefRecord));
    }

    return new JSONArray(list);
