在Android应用程序中提取短信的内容

Question

我正在编写一个应用程序，在接收短信时应该提取短信的内容，并将字符串分成两部分和单独的变量。这是我尝试过的。但即使没有错误，代码也不起作用。

    public void onReceive(Context context, Intent intent) {

    // Retrieves a map of extended data from the intent.
    final Bundle bundle = intent.getExtras();


    try {

        if (bundle != null) {

            final Object[] pdusObj = (Object[]) bundle.get("pdus");


            for (int i = 0; i < pdusObj.length; i++) {

                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                String senderNum = phoneNumber;
                String message = currentMessage.getDisplayMessageBody();

                Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);
                int duration = Toast.LENGTH_LONG;
                Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration);
                toast.show();
              // String[] arr=message.split(",");
                StringTokenizer tokenizer = new StringTokenizer(message, ",");
                Toast toast1 = Toast.makeText(context, "tokenizer", Toast.LENGTH_SHORT);
                toast1.show();
                int numberOfTokens = tokenizer.countTokens();
                String[] splitArr = new String[numberOfTokens];

                    splitArr[0] = tokenizer.nextToken();
                    splitArr[1] = tokenizer.nextToken();
                    Toast toast3 = Toast.makeText(context, splitArr[0], Toast.LENGTH_SHORT);
                    toast3.show();
                    Toast toast2 = Toast.makeText(context, "split", Toast.LENGTH_SHORT);
                    toast2.show();
                String lat=splitArr[0];
                String lng=splitArr[1];
                Double lat1=Double.valueOf(lat);
                Double lng1=Double.valueOf(lng);

}} }
