自定义通知（notification）

首先需要用到三个类：RemoteViews,NotificationCompat.Builder,NotificationManager

        RemoteViews view = new RemoteViews(mContext.getPackageName(),R.layout.icon_notification);
        NotificationCompat.Builder notificationB = new NotificationCompat.Builder(mContext);
        NotificationManager notificationM = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
        notificationB.setSmallIcon(R.mipmap.ic_launcher);
        view.setImageViewResource(R.id.img_icon,R.mipmap.ic_launcher);
        view.setTextViewText(R.id.tv_title,"英雄联盟联赛");
        view.setTextViewText(R.id.tv_content,"您关注的战队正在比赛哦");
        notificationB.setContent(view);
        notificationM.notify(3,notificationB.build());

实例化一个RemoteViews，传入两个参数，包名和自定义的布局ID。

通过NotificationCompat.builder 设置setSmallIcon(必须有)

remoteview设置布局

NotificationManager启动通知
