android 创建通知栏Notification

Posted 2020-09-11 zhchoutai

		///// 第一步：获取NotificationManager
		NotificationManager nm = (NotificationManager) 
				getSystemService(Context.NOTIFICATION_SERVICE);

		///// 第二步：定义Notification
		Intent intent = new Intent(this, OtherActivity.class);
		//PendingIntent是待运行的Intent
		PendingIntent pi = PendingIntent.getActivity(this, 0, intent,
				PendingIntent.FLAG_CANCEL_CURRENT);
		Notification notification = new Notification.Builder(this)
				.setContentTitle("title")
				.setContentText("text")
				.setSmallIcon(R.drawable.ic_launcher).setContentIntent(pi)
				.build();
		notification.flags = Notification.FLAG_NO_CLEAR;
		
		/////第三步：启动通知栏，第一个參数是一个通知的唯一标识
		nm.notify(0, notification);
		
		//关闭通知
		//nm.cancel(0);
