我正在处理邮件应用程序,并希望在新邮件到达时更新我的​​自定义listView。我已经尝试了几种方法来做到这一点但是没有成功...请帮助完整的描述因为新的android。这是我的代码

public class SMSBroadcastReceiver extends BroadcastReceiver {
    Messages message1;
    MessageDbHelper db;
    Context context=null;
    SmsInboxList smsInboxList;
    BroadcastReceiver br;
    //  ADapter adap;
    private static final String ACTION = "android.provider.Telephony.SMS_RECEIVED";
    IntentFilter intentFilter=new IntentFilter(ACTION);

    @SuppressLint("SimpleDateFormat")
    @Override
    public void onReceive(Context context, Intent intent) {

        // Retrieves a map of extended data from the intent.
        Bundle bundle = intent.getExtras();
        message1 = new Messages();
        this.context=context;
        //      context = context.getApplicationContext();
        smsInboxList = new SmsInboxList();
        //      adap=new ADapter(context, R.id.listView_Conversation);
        MessageDbHelper dbMessagedbHelper = new MessageDbHelper(context, null,null, 0);
        db = dbMessagedbHelper;

        try {

            if (bundle != null) {

                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();
                    Long localLong = Long.valueOf(currentMessage.getTimestampMillis());
                    String datae = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date(localLong.longValue()));

                    /*****************
                     ** @here we getting data for notification
                     **

                    try {
                        message1.body(message);
                        message1.number(senderNum);
                        message1.date(datae);
                        message1.type("1");
                        Log.i(""    ,   "body++++++++++++++++" + message1.body);
                        Log.i(""    ,   "num+++++++++++" + message1.number);

                        db.insertDataInMsgTable(message1);
                        createNotification(context, message1);

                    } catch (Exception e) {
                        Log.i("", "except" + e);

                    }
                    Log.i("SmsReceiver", "senderNum: " + senderNum
                            + "; message: " + message);
                }
            }
        }
    }

    public void createNotification(Context context, Messages message1) {

        Log.i("", "get body====" + message1.body + "---" + message1.number);
        Intent intent = new Intent(context, SmsInboxList.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,intent, 0);
        Notification notification = new NotificationCompat.Builder(context)
                .setContentTitle("From: " + message1.number)
                .setContentText(message1.body).setContentIntent(pendingIntent)
                .setSmallIcon(R.drawable.app_icon).build();

        NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        notification.flags |= Notification.DEFAULT_LIGHTS;
        notification.flags |= Notification.FLAG_AUTO_CANCEL;

        manager.notify(0, notification);

        try
        {
        smsInboxList.adap.notifyDataSetChanged();
        }
        catch(Exception e)
        {
            Log.i("", "error in addd==="+e);
            e.printStackTrace();
        }
    }   
}
