public void notification_onclick(View view){

        Resources res = Activitywenben.this.getResources();
        //1.获取状态栏消息管理器
        NotificationManager manager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

        //3.实现页面跳转，构建意图
        Intent intent = new Intent(this,Activitybase.class);

        //4.获取PendingIntent
        PendingIntent pendingIntent = PendingIntent.getActivity(this,1,intent,0);

        //2.构建消息  用Builder构建 方法链调用
        Notification nt = new Notification.Builder(this)

                .setSmallIcon(R.drawable.anniu2)
                .setContentTitle("这是一条消息通知")
                .setContentText("这是通知内容：点击打开新的界面")
                .setContentIntent(pendingIntent)
                .setTicker("显示在状态栏中的信息")
                .setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.mm))
                .setAutoCancel(true)
                .setDefaults(Notification.DEFAULT_ALL)
                .build();

        //3.交给管理器发出消息
        manager.notify(0,nt);
