android實現狀態列添加表徵圖的函數執行個體_Android

本文執行個體講述了android實現狀態列添加表徵圖的函數。分享給大家供大家參考。具體如下：

private void showNotification() {  // 建立一個NotificationManager的引用  NotificationManager notificationManager = (NotificationManager)   AutoFile.this.getSystemService(android.content.Context.NOTIFICATION_SERVICE);  // 定義Notification的各種屬性  Notification notification = new Notification(R.drawable.dvd,   "天籟之音播放器", System.currentTimeMillis());  notification.flags |= Notification.FLAG_ONGOING_EVENT; // 將此通知放到通知欄的"Ongoing"即"正在運行"組中  notification.flags |= Notification.FLAG_NO_CLEAR; // 表明在點擊了通知欄中的"清除通知"後，此通知不清除，經常與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;  // 設定通知的事件訊息  CharSequence contentTitle = "天籟之音現正播放……"; // 通知欄標題  CharSequence contentText = "ameyume"; // 通知欄內容  Intent notificationIntent = new Intent(AutoFile.this, MyPlayerService.class); // 點擊該通知後要跳轉的Activity  PendingIntent contentItent = PendingIntent.getActivity(AutoFile.this, 0,   notificationIntent, 0);  notification.setLatestEventInfo(AutoFile.this, contentTitle, contentText,   contentItent);  // 把Notification傳遞給NotificationManager  notificationManager.notify(0, notification); } 

要刪除表徵圖，用以下代碼：

// 啟動後刪除之前我們定義的通知 NotificationManager notificationManager = (NotificationManager) this  .getSystemService(NOTIFICATION_SERVICE); notificationManager.cancel(0);

希望本文所述對大家的Android程式設計有所協助。
