本文介绍了如何删除通知在android系统？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在开发中，我收到多个通知的应用程序。我成功地接收不同数据的多个通知，但是当我使用 setAutoCancel（真）; 的删除通知，我收到多个通知，它显示了通知栏上只剩下最后通知。搜索结果
在这里，我的问题可见多个通知，但如果我删除 setAutoCancel（真）; 方法，我可以成功地接收多个通知，但我要删除多个通知的通知。

解决方案
使用的NotificationManager取消通知。你只需要提供您的通知标识
mNotificationManager.cancel（YOUR_NOTIFICATION_ID）;
I am developing an application in which I receive multiple notifications. I am successfully receiving multiple notifications with different data, but when I use setAutoCancel(true); for remove notification, and I receive multiple notifications it shows only last notification on notification bar.
Here my problem shows multiple notification, but if I remove setAutoCancel(true); method I can successfully receive multiple notifications, but I want to remove notification with multiple notifications.
GcmIntentService.java:
public class GcmIntentService extends IntentService {
Context context;
//System.currentTimeMillis();
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(RegIdDTO.REG_ID,"Send error: " +
extras.toString());
} else if (GoogleCloudMessaging.
MESSAGE_TYPE_DELETED.equals(messageType)) {
sendNotification(RegIdDTO.REG_ID,"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(RegIdDTO.REG_ID,msg);
Log.i(TAG, "Received: " + extras.toString());
}
}
GcmBroadcastReceiver.completeWakefulIntent(intent);
}
private void sendNotification(long when,String msg) {
mNotificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
Intent myintent = new Intent(this, ReceiveActivity.class);
myintent.putExtra("message", msg);
myintent.setData(Uri.parse("content://"+when));
PendingIntent contentIntent = PendingIntent.getActivity(this, 1,

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_stat_gcm)
.setContentTitle("Event tracker")
.setContentText("Events received");
Notification notification=mBuilder.build();
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);

default:
mBuilder.setDefaults(Notification.DEFAULT_SOUND);
}
mBuilder.setContentIntent(contentIntent);
mBuilder.setAutoCancel(true);
mNotificationManager.notify((int) when, mBuilder.build());
}
my receive activity
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_receive);
Intent intent = getIntent();
name = (TextView) findViewById(R.id.name);
deal = (TextView) findViewById(R.id.deal);

String message = intent.getExtras().getString("message");
try {

String stime = json.getString("name");
name.setText(stime);
String slecturename = json.getString("deal");
deal.setText(slecturename);
String sroom = json.getString("valid");
valid.setText(sroom);
String sfaculty = json.getString("address");
address.setText(sfaculty);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
解决方案
Use the NotificationManager to cancel your notification. You only need to provide your notification id
mNotificationManager.cancel(YOUR_NOTIFICATION_ID);
