Question

我有一个本地通知，在我的一个接收器中设置。通知我想要打开一个特定的活动。以下是我的代码。

NotificationCompat.Builder builder =
            (NotificationCompat.Builder) new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentTitle("Its Your day!!")
                    .setContentText(message)
                    .setAutoCancel(true);

    Intent notificationIntent = new Intent(context, MainActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    builder.setContentIntent(contentIntent);
    // Add as notification
    NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(times, builder.build());

但这不起作用。单击通知时，它只会从状态栏中删除通知。我错过了什么吗？

试试这个：

Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

而不是：

Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent,
        PendingIntent.FLAG_UPDATE_CURRENT);

在通知构建器代码之前使用此代码。

现在这是完整版：

Intent intent = new Intent(this, MainActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

NotificationCompat.Builder builder =
            (NotificationCompat.Builder) new NotificationCompat.Builder(context)
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentTitle("Its Your day!!")
                    .setContentText(message)
                    .setAutoCancel(true)
                    .setContentIntent(pendingIntent);

NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

notificationManager.notify(times, notificationBuilder.build());

尝试使用它。我希望你能得到你想要的答案。

在{Intent}上添加Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP作为Flag。喜欢 -

notificationIntent .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);

还提供通知的唯一ID。喜欢 -

    int uniqueNotificationId = (int) (System.currentTimeMillis() & 0xfffffff);
    PendingIntent contentIntent = PendingIntent.getActivity(context, uniqueNotificationId , notificationIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);

同样在 -

manager.notify(uniqueNotificationId , builder.build());

点击打开活动的本地通知
