[Android(安卓)Pro] Notification的使用

Android 4.0以前：

1：普通的notification

private static final int NOTIFY_ID = 0;notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);    private void showNotification(Store store) {        Notification notification = new Notification();        notification.flags |= Notification.FLAG_SHOW_LIGHTS;        notification.flags |= Notification.FLAG_AUTO_CANCEL;        notification.defaults = Notification.DEFAULT_ALL;        notification.icon = R.drawable.ic_launch;        notification.when = System.currentTimeMillis();        Intent intent = new Intent(this,AlarmActivity.class);        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);         intent.putExtra("store", store);        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,intent, PendingIntent.FLAG_UPDATE_CURRENT);//FLAG_ONE_SHOT         //Change the name of the notification here        notification.setLatestEventInfo(this, store.getStoreName()+"("+store.getDistance()+")", store.getAddress(), contentIntent);        notificationManager.notify(NOTIFY_ID, notification);    }

2：将服务service设置为前台notification

public class MyService extends Service {    @Override    public void onCreate() {        super.onCreate();        setServiceForground();    }    @SuppressWarnings("deprecation")    public void setServiceForground() {        Notification notification = new Notification(R.drawable.ic_launcher,        "my_service_name", System.currentTimeMillis());
 　　　　//要添加newtask        PendingIntent p_intent = PendingIntent.getActivity(this, 0, new Intent(                this, MainActivity.class), 0);        notification.setLatestEventInfo(this, "MyServiceNotification",                "MyServiceNotification is Running!", p_intent);        startForeground(0x1982, notification);    }
    @Override    public IBinder onBind(Intent intent) {        return null;    }}

Android 4.0 以后：

将服务service设置为前台notification

public class MyService extends Service {    @Override    public void onCreate() {        super.onCreate();        setServiceForground();    }    @Override    public void onDestroy() {        super.onDestroy();    }    public void setServiceForground() {        Notification.Builder build = new Notification.Builder(this);//      PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(//            this, MainActivity.class), 0);//      build.setContentIntent(contentIntent);        build.setSmallIcon(R.drawable.ic_launcher);            build.setContentTitle("MyServiceNotification");        build.setContentText("MyServiceNotification is Running!");        startForeground(0x1982, build.build());    }    @Override    public IBinder onBind(Intent intent) {        return null;    }}
