Android stackBuilder.addParentStack不工作-导航到主活动（OnBackPressed）

当用户单击通知时，它将打开工作正常的新活动。但当我按下后退按钮时，它关闭了应用程序

我想要什么？ 当我点击后退按钮时，它每次都返回MainActivity（所选活动）

 private void generateNotificationNew(Context context, String message,String pushIdmessage) {

        Intent resultIntent = null;

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(context.getString(R.string.app_name))
                        .setAutoCancel(true)
                        .setContentText(message);



        resultIntent = new Intent(context,ResultActivity.class);
        //Intent resultIntent = new Intent(this, AvailableJobActivity.class);
        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(
                        5,
                        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(0, mBuilder.build());
    }

stackBuilder.addParentStack

或

stackBuilder.addnextint

可能无法正常工作。

任何其他选项谢谢。

对于生成通知您需要输入以下代码

NotificationCompat.Builder builder = new NotificationCompat.Builder(this).setSmallIcon(R.mipmap.ic_launcher).setContentTitle("Notificatin Title")
                .setContentText("message");
Intent notificationIntent = new Intent(this , ResultActivity);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addNextIntent(notificationIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0 , PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify( 0 , builder.build());

对于handleback事件，您需要在结果活动中的onBackPressed（）中检查以下内容

@Override
public void onBackPressed() {
    if(this.isTaskRoot())
        startActivity(new Intent(this , MainActivity.class));
    super.onBackPressed();
}

现在，您可以从通知启动的活动重定向到MainActivity。。 享受它…-）
