Answer 1

您可以使用此代码。将Main.Class更改为您的活动类，并根据需要将标题和内容文本更改。

String ns = Context.NOTIFICATION_SERVICE;
                NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);


                    int icon = R.drawable.ic_action_search;
                    CharSequence tickerText = "Pet Parrot";
                    long when = System.currentTimeMillis();

                    Notification notification = new Notification(icon,
                            tickerText, when);
                    notification.flags |= Notification.FLAG_AUTO_CANCEL;
                    Context context = getApplicationContext();
                    CharSequence contentTitle = "Hungry!";
                    CharSequence contentText = "your parrot food meter is: ";
                    Intent notificationIntent = new Intent(context,
                            Main.class);
                    PendingIntent contentIntent = PendingIntent
                            .getActivity(context, 0, notificationIntent, 0);

                    notification.setLatestEventInfo(context, contentTitle,
                            contentText, contentIntent);

                    mNotificationManager.notify(1, notification);
                    // Log.d("test", "Saving Data to File from Service.");

Answer 2

以下一行：

PendingIntent activity = PendingIntent.getService(this, 0, intent, 0);

应该是这样的：

PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);

因为您尝试启动Activity，而不是Service。希望这会有所帮助。

使用NotificationManager进入Android服务
