我工作的消息應用程序，並想在新消息到達時更新我的自定義listView。我已經嘗試了幾種方法來做到這一點，但不成功...請幫助完整的描述原因新的Android。這裏我的代碼`public class SMSBroadcastReceiver extends BroadcastReceiver {如何更新我的自定義listView顯示？
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);
Log.i("" , "date+++++++++++" + message1.date);
Log.i("" , "typeeee++++++++++++" + message1.type);
db.insertDataInMsgTable（message1）; createNotification（context，message1）;
} catch (Exception e) {
Log.i("", "except" + e);
}
Log.i("SmsReceiver", "senderNum: " + senderNum
+ "; message: " + message);
公共無效createNotification（上下文上下文中，消息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();
}
