我创建从服务用下面的代码的通知:点击通知开始活动两次
NotificationManager notificationManager = (NotificationManager) ctx
.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence tickerText = "bla ...";
long when = System.currentTimeMillis();
Notification notification = new Notification(R.drawable.icon,
tickerText, when);
Intent notificationIntent = new Intent(ctx, SearchActivity.class).
putExtra(SearchActivity.INTENT_SOURCE,
MyNotificationService.class.getSimpleName());
PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0,
notificationIntent, 0);
notification.setLatestEventInfo(ctx, ctx.getString(R.string.app_name),
tickerText, contentIntent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(1, notification);
日志清楚地说,该方法startActivity被调用的两倍:

他们为什么开始两次?
在计算器上有两个相同的问题:here和here。 但他们没有解释最初的问题可能是什么,他们不适合我。例如。更改为launchMode singleTop不适用于我,它应该根据official docs(请参阅调用搜索对话框)在不更改launchMode的情况下工作。
不过我也试过以下标志添加到notificationIntent
Intent.FLAG_ACTIVITY_CLEAR_TOP | PendingIntent.FLAG_UPDATE_CURRENT
但问题依然存在。
我从头开始创建一个测试项目,同样的问题存在那里(在三星设备上)。对于模拟器(2.1 + 2.2)似乎都很好。 – Karussell 2011-04-05 10:03:24
