Android的通知恢复活动 [英] Android notification Resume Activity

问题描述

我试图让当用户暂停我的应用程序的通知。所以，使其更容易，用户可以快速使用notificaction去申请。这是code我使用。它适用于所有版本的Andr​​oid 4.0之前，我不知道这是问题

I'm trying to make a notification when users pause my app. So to make it easier, users can go quickly to the application using notificaction. This is the code i'm using. It works for all versions before android 4 and i don't know which is the problem

 NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)    
                .setContentTitle("Titulo")
                .setContentText("Titulo");

        mBuilder.setOngoing(true);

        // Creates an explicit intent for an Activity this 
        Intent resultIntent = new Intent(getApplicationContext(), MainActivity.class);
        // put the flags
        resultIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(MainActivity.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        // mId allows you to update the notification later on.
        mNotificationManager.notify(mId, mBuilder.build());

所以，当我在Android 4.0及更高preSS通知，再次创造，而不是简历的活动。任何帮助请，我不能使它工作。

So when i press the notification in android 4.0 and higher, the activity is created again instead of resume. any help please, i can't make it work.

编辑（忘了清单singletop）

EDIT ( forget about manifest singletop )

的android：launchMode =singleTop同样的结果，没有工作......

android:launchMode="singleTop" same result, not working...

我的活动包含的地图。我使用谷歌地图的新版本。 V2。

My activity contains a map. I'm using the new version of google maps. v2.

推荐答案

我只是想PendingIntent.FLAG_CANCEL_CURRENT，似乎为我工作

I just tried PendingIntent.FLAG_CANCEL_CURRENT and seems to work for me

public void showNotification(String header,String message){

            // define sound URI, the sound to be played when there's a notification
            Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

            Intent intent = new Intent(this, MainActivity.class);

            //PendingIntent.FLAG_CANCEL_CURRENT will bring the app back up again
            PendingIntent pIntent = PendingIntent.getActivity(MainActivity.this,PendingIntent.FLAG_CANCEL_CURRENT, intent, 0);

            Notification mNotification = new Notification.Builder(this)
                .setContentTitle(header)
                .setContentText(message)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentIntent(pIntent)
                .setSound(soundUri)

                .addAction(R.drawable.ic_launcher, "View", pIntent)
                .addAction(0, "Remind", pIntent)
                .setOngoing(true)//optional
                .build();

            NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

            notificationManager.notify(0, mNotification);
}
