我创建了一个 Notification，我希望它在单击时打开一个 Fragment。它通常工作正常，但是当我当时在我的应用程序中打开另一个 fragment 时，它不起作用。
例如，我有两个 fragment :NoticiaFrag 和 EventoFrag。如果我打开我的应用程序并打开 NoticiaFrag 后按下设备的主页按钮最小化应用程序并收到 EventoFrag 的通知，当我单击通知时打开 NoticiaFrag 而不是 EventoFrag。
为了完成这项工作，我需要使用后退按钮关闭应用程序。应用程序关闭后它工作正常。我想我需要在点击通知时重新打开应用程序，但我不知道如何。
从 Notification 打开 Fragment 的方法在 CustomDrawerLayout 中，调用了 openFrag()。
我该如何解决这个问题？
通知
public class SendNotification {
public SendNotification(Context context, String title, String tickerText, String message, String url) {
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent;
Intent intent = new Intent(context, CustomDrawerLayout.class);
Bundle bd = new Bundle();
bd.putString("url", url);
intent.putExtras(bd);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.logo)
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setTicker(tickerText)
.setContentTitle(title)
.setShowWhen(true)
.setWhen(System.currentTimeMillis())
.setContentText(message);
mBuilder.setContentIntent(contentIntent);
Notification notification = mBuilder.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.vibrate = new long[]{150, 300, 150, 600};
mNotificationManager.notify(AndroidSystemUtil.randInt(), notification);
}
}

最佳答案
问题是 Android 默认情况下不会向已经运行的 Activity 传递新的 Intent。如果您通过后退按钮关闭您的应用程序，Activity 将被销毁，下次调用 startActivity() 时将创建一个新实例并创建新的 Intent 交付。如果您通过主页按钮离开 Activity，Activity 不会被销毁。当您在这种情况下调用 startActivity() 时，已经运行的 Activity 实例被带到前台，但是一个新的 Intent 是 < em>未交付。
要更改此行为，您可以使用 launchMode="singleTop" 在 list 中定义您的 Activity :
<activity
...
android:launchMode="singleTop"
...
>
</activity>
在这种情况下，Android 将通过onNewIntent() 传递一个新的Intent，您可以override :
This is called for activities that set launchMode to "singleTop" in their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag when calling startActivity(Intent). In either case, when the activity is re-launched while at the top of the activity stack instead of a new instance of the activity being started, onNewIntent() will be called on the existing instance with the Intent that was used to re-launch it.
刚刚注意到您传递给 Intent 的标志。在这种情况下，您可能只需要在 Activity 中覆盖 onNewIntent()。
我自己也遇到过这个问题，问了一个问题here .该问题、已接受的答案和评论中有更多背景信息。
