    Intent intent = new Intent(_context, MainActivity.class);
    PendingIntent activity = PendingIntent.getActivity(_context, 0, intent, 0);
    notification.contentIntent = activity;

从通知进入MainActivity如果MainActivity已经打开，因此我需要出口的两倍。这是一个falg问题，我该怎么办？

Enter MainActivity from notification if MainActivity is already opened, thus I need exit twice. Is this a falg problem, what should I do?

推荐答案

是的，它是...你要这个标志添加到您的待处理的意图。

Yes It is.. You have to add this flag to your pending Intent.

Intent intent = new Intent(_context, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP|   Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent activity = PendingIntent.getActivity(_context, 0, intent, 0);

在这里拍的形式，
