android - 活动不显示

Question

我创建了一个创建通知的广播接收器，通过单击一个通知启动了一个活动，该活动正在启动但我无法查看它，我正在使用以下代码：

private NotificationManager notificationManager;
    @Override
public void onReceive(Context context, Intent intent) {
    if (notificationManager == null) {
        notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
    }
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
            .setTicker("Its Ticker")
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("Notification Title")
            .setContentText("Its Content")
            .setAutoCancel(true)
            .setContentIntent(PendingIntent.getActivity(context,0,new Intent(context, NotificationDialog.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK),0));
    notificationManager.notify("interstitial_tag", 0, builder.getNotification());

}

注意：NotificationDialog.java是我的活动，此活动在我调试但未查看时正在运行。尝试了几个小时但找不到任何答案，任何建议将不胜感激。

Answer 1

使用FLAG_ACTIVITY_CLEAR_TOP而不是FLAG_ACTIVITY_CLEAR_TASK

private NotificationManager notificationManager;
    @Override
public void onReceive(Context context, Intent intent) {
    if (notificationManager == null) {
        notificationManager = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
    }
    NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
            .setTicker("Its Ticker")
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("Notification Title")
            .setContentText("Its Content")
            .setAutoCancel(true)
            .setContentIntent(PendingIntent.getActivity(context,0,new Intent(context, NotificationDialog.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP),0));
    notificationManager.notify("interstitial_tag", 0, builder.getNotification());

}
