RecycleView 实现多布局

最近的一个新需求，简单描述下吧：

需求：

　　

目标样式如图所示，我们需要根据需求动态添加网关和设备。

目标有了下面就是怎么实现了。首先我们选用的是RecycleView

那么主要目标就成了 在recycleView下如何实现多布局（我们看到网关和设备的布局不同）

首先写两个布局（一个网关 ， 一个设备）

网关布局样式：

设备布局样式：

这些都比较简单，在这里就不赘述。

RecycleView的基本用法：

　　1）引入包

　　2）在布局中使用控件

　　3）在activity中绑定并使用recycleView

　　4）自定义recycleView的适配器

这些在我之前的博客有介绍，本篇主要说明多布局应当如何来写

适配器：

先上代码：

import android.content.Context;

import android.support.v7.widget.RecyclerView.ViewHolder;

import android.widget.Toast;
