本文实例讲述了android实现状态栏添加图标的函数。分享给大家供大家参考。具体如下:
private void shownotification() { // 创建一个notificationmanager的引用 notificationmanager notificationmanager = (notificationmanager) autofile.this.getsystemservice(android.content.context.notification_service); // 定义notification的各种属性 notification notification = new notification(r.drawable.dvd, "天籁之音播放器", system.currenttimemillis()); notification.flags |= notification.flag_ongoing_event; // 将此通知放到通知栏的"ongoing"即"正在运行"组中 notification.flags |= notification.flag_no_clear; // 表明在点击了通知栏中的"清除通知"后,此通知不清除,经常与flag_ongoing_event一起使用 notification.flags |= notification.flag_show_lights; notification.defaults = notification.default_lights; notification.ledargb = color.blue; notification.ledonms = 5000; // 设置通知的事件消息 charsequence contenttitle = "天籁之音正在播放……"; // 通知栏标题 charsequence contenttext = "ameyume"; // 通知栏内容 intent notificationintent = new intent(autofile.this, myplayerservice.class); // 点击该通知后要跳转的activity pendingintent contentitent = pendingintent.getactivity(autofile.this, 0, notificationintent, 0); notification.setlatesteventinfo(autofile.this, contenttitle, contenttext, contentitent); // 把notification传递给notificationmanager notificationmanager.notify(0, notification); }
要删除图标,用以下代码:
// 启动后删除之前我们定义的通知 notificationmanager notificationmanager = (notificationmanager) this .getsystemservice(notification_service); notificationmanager.cancel(0);
