android Notification總結

在發送一個Notification前，咱們須要準備好一個NotificationManager

NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

notification = new Notification();

一、定義一個Notification具有的三個基本參數icon，tickerText，以及添加打開關閉方式

notification.icon = R.drawable.ic_launcher;

notification.tickerText = "注意了，我被扔到狀態欄了";

 

notification.flags = Notification.FLAG_AUTO_CANCEL;// 點擊通知以後自動消失

notification.defaults=notification.DEFAULT_SOUND|notification.DEFAULT_VIBRATE; //notification被notify的時候，觸發默認聲音和默認震動

 

二、爲notification添加一個意圖(Intent)：

Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT);
notification.contentIntent = contentIntent;

 

因爲Notification的包裝內容爲Intent，咱們就能夠方便地爲通知被點擊的觸發的事件傳值：

openintent.putExtra("isRead", true);
openintent.putExtra("name", "CaiYu");

 

四、發送通知

manager.notify(notifacation_id, notification);//notifacation_id由本身指定，爲每個Notification對應的惟一標誌

 

五、自定義通知欄

RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notify_view);//自定義的layout
contentView.setImageViewResource(R.id.notify_imageLog, R.drawable.ic_launcher);//layout中的控件
contentView.setTextViewText(R.id.notify_name, "1");
notification.contentView = contentView;

 

六、刪除、更改某些通知

manager.cancel(notifacation_id);

manager.cancelAll();

manager.notify(notifaction_id,newNotification);

 

七、用notification.builder實現

NotificationCompat.Builder builder = new Builder(context);
builder.setContent(remoteViews).setSmallIcon(R.drawable.icon).setLargeIcon(icon).setOngoing(true).setTicker("music is playing");
manager.notify(notifaction_id, builder.build());
