我正在开发一个应用程序，我必须从gcm服务器接收通知我已成功收到通知，这里有两个问题。
1）我成功阅读了多个通知，但所有消息通知只显示一条消息，仅显示最后一个数据。
2）每当打开通知时，通知栏上的Notication图标都不会消失。我写了删除通知的代码，它不起作用请帮帮我。
public class GcmIntentService extends IntentService{
Context context;
public static int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
public static final String TAG = "GCM Demo";
public GcmIntentService() {
super("GcmIntentService");
// TODO Auto-generated constructor stub
}
@Override
protected void onHandleIntent(Intent intent) {
// TODO Auto-generated method stub
Bundle extras = intent.getExtras();
String msg = intent.getStringExtra("message");
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.
MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {
sendNotification("Send error: " + extras.toString());
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification("Deleted messages on server: " +
extras.toString());
// If it's a regular GCM message, do some work.
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_MESSAGE.equals(messageType)) {
// This loop represents the service doing some work.
for (int i=0; i<5; i++) {
Log.i(TAG, "Working... " + (i+1)
+ "/5 @ " + SystemClock.elapsedRealtime());
try {
Thread.sleep(500);
} catch (InterruptedException e) {
}
}
Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
// Post notification of received message.
//sendNotification("Received: " + extras.toString());
sendNotification(msg);
Log.i(TAG, "Received: " + extras.toString());
}
}
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
private void sendNotification(String msg) {
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent myintent = new Intent(this, ReceiveActivity.class);
myintent.putExtra("message", msg);

int numMessages = 0;
// Moves events into the big view
for (int i=0; i < events.length; i++) {
inboxStyle.addLine(events[i]);
}
mBuilder.setStyle(inboxStyle);
*/
AudioManager am = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
/* Even if the mode is set to "Sound & Vibration" in the phone,
* the status code that getRingerMode() returns is RINGER_MODE_NORMAL.
*/
switch (am.getRingerMode())
{
case AudioManager.RINGER_MODE_VIBRATE:
mBuilder.setDefaults(Notification.DEFAULT_VIBRATE);
break;
case AudioManager.RINGER_MODE_NORMAL:
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
break;
default:
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
}
mBuilder.setContentIntent(contentIntent);
// TO clear notification
mNotificationManager.notify(NOTIFICATION_ID++, mBuilder.build());

请添加此方法并在此方法中传递您的通知ID。 在您的主要活动的resume方法中调用此方法..
public void CancelNotification(Context ctx, int notifyId) {
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager nMgr = (NotificationManager) ctx
.getSystemService(ns);
nMgr.cancel(notifyId);
}
我希望它对你有用。

请检查此代码：
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("Event tracker")
.setContentText("Events received")
NotificationCompat.InboxStyle inboxStyle =
new NotificationCompat.InboxStyle();
String[] events = new String[6];
// Sets a title for the Inbox style big view
inboxStyle.setBigContentTitle("Event tracker details:");
...
// Moves events into the big view
for (int i=0; i < events.length; i++) {
inboxStyle.addLine(events[i]);
}
// Moves the big view style object into the notification object.
mBuilder.setStyle(inBoxStyle);
...
// Issue the notification here.
请检查
我希望它对你有所帮助。

这是不正确的：
mNotificationManager.notify(NOTIFICATION_ID++, mBuilder.build());
mBuilder = new NotificationCompat.Builder(
this).setSmallIcon(R.drawable.ic_stat_gcm)
.setAutoCancel(true)
.setContentTitle("GCM Notification")
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.setContentText(msg);
mNotificationManager.cancel(NOTIFICATION_ID);
您无需为取消通知创建其他通知构建器。您只需在调用mBuilder.setAutoCancel(true)之前为原始构建器调用mNotificationManager.notify。
因此，您应该用以下代码替换该代码：
mBuilder.setAutoCancel(true)
mNotificationManager.notify(NOTIFICATION_ID++, mBuilder.build());
