android中创建通知栏Notification代码实例

///// 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是待执行的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，第一个参数是一个通知的唯一标识
        nm.notify(0, notification);

        //关闭通知
        //nm.cancel(0);
