Android :使用一个服务类来处理多个通知？

// MyNotificationService.java
public class MyNotificationService extends Service {
    private static final int NOTIFICATION_ID = 1;

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        String title = intent.getStringExtra("title");
        String content = intent.getStringExtra("content");

        sendNotification(title, content);

        return START_NOT_STICKY;
    }

    private void sendNotification(String title, String content) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notification_icon)
                .setContentTitle(title)
                .setContentText(content)
                .setPriority(NotificationCompat.PRIORITY_DEFAULT);

        NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
        notificationManager.notify(NOTIFICATION_ID, builder.build());
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

// MainActivity.java
public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 启动服务类来发送通知
        Intent intent = new Intent(this, MyNotificationService.class);
        intent.putExtra("title", "Notification Title");
        intent.putExtra("content", "Notification Content");
        startService(intent);
    }
}
