通知将应用程序置于最前面，无需更改活动 [英] Notification bring app to front without change activity

问题描述

我想创建一个通知，当它单击时将使我的应用程序显示在最前面，但不更改(重新加载或导航)显示的上一个活动.

I want to create notification that when it clicked will bring my app to front but without changing (reload or navigate out) the last activity that was shown.

我尝试过:

setContentIntent(PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT))

但是在新的Android 4.3中，该应用程序名列前茅，但它也启动了 MainActivity 的新实例，我不希望这样做.

But in the new Android 4.3 the application brought to front, but its also start a new instance of MainActivity, and I don't want this.

我希望我的应用程序从显示的上一个活动继续执行.
该怎么做?

I want that my app will continue from the last activity that was shown.
How to do that?

推荐答案

您永远不会设置 Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT .该标志是由Android在将活动置于最前面时设置的.您设置它无效.

You don't ever set Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT. That flag is set by Android when it brings the activity to the front. You setting it has no effect.
