实现代码:

Button sendNotice = (Button) findViewById(R.id.send_notice);
        sendNotice.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Notification.Builder builder = new Notification.Builder(MainActivity.this);
                builder.setSmallIcon(R.mipmap.ic_launcher);  //设置状态栏里面的图标（小图标）
                builder.setTicker("状态栏上显示");  //设置状态栏的显示的信息
                builder.setWhen(System.currentTimeMillis());  //设置通知来到的时间
                builder.setAutoCancel(true);  //设置可以清除
                builder.setContentTitle("标题");  //设置通知的标题
                builder.setContentText("内容");  //设置通知的内容
                builder.setOngoing(true);

            /*
             * // 设置声音(手机中的音频文件) String path =
             * Environment.getExternalStorageDirectory() .getAbsolutePath() +
             * "/Music/a.mp3"; File file = new File(path);
             * builder.setSound(Uri.fromFile(file));
             */
                //通知声音
                builder.setSound(Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "5"));  //获取Android多媒体库内的铃声
                //振动
                builder.setVibrate(new long[]{0, 200, 200, 200}); //需要真机测试


                //通过getSystemService获取系统Service
                NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
//                Notification notification = builder.build();  //提示api15不用build()
                Notification notification = builder.getNotification();
                // notification.flags =Notification.FLAG_ONGOING_EVENT;

                Intent intent = new Intent(MainActivity.this, MainActivity.class);  //构建一个Intent
                PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);  //封装一个Intent
                builder.setContentIntent(pendingIntent);  //设置通知主题的意图

                notificationManager.notify(1, notification);
            }
        });
