如何在点击时清除Android上的通知

Question

每次我点击通知时，活动都会弹出在屏幕上，我用它在状态窗口中触发通知。

我想在用户点击时清除通知，但每次都会打开活动。

我尝试使用标志不仅在通知上，而且在PendingIntent和Intents上。

我的代码：

NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 

Notification not = new Notification(R.drawable.ic_launcher, 
     "this is not important", System.currentTimeMillis()); 

Context context = MainActivity.this; 

CharSequence title = "You have been notified"; 
CharSequence details = "contiue with work"; 

not.flags = Notification.FLAG_AUTO_CANCEL; 

Intent intent = new Intent(context, MainActivity.class); 
PendingIntent pending = PendingIntent.getActivity(context, 0, intent, PendingIntent. FLAG_ONE_SHOT); 

not.setLatestEventInfo(context, title, details, pending); 
nm.notify(0, not); 

也：

PendingIntent pending = PendingIntent.getActivity(context, 0, intent, 0); 

和：

PendingIntent pending = PendingIntent.getActivity(context, 0, intent, Notification.FLAG_AUTO_CANCEL); 

我每次点击通知活动都会在屏幕上，我只是想清楚通知。

这里是logcat的

Answer 1

你不应该的待定意图

删除以下行

PendingIntent pending = PendingIntent.getActivity(context, 0, intent, PendingIntent. FLAG_ONE_SHOT); 

，并发送空到

not.setLatestEventInfo(context, title, details, null);
