# 融云 集成会话列表加头布局

• 这个是在用IMKit的时候会出现的问题，因为布局什么的都是第三方的，那么怎么解决呢？要么改成IMLib，要么就用混合的。我是用的混合集成的。
• 注意只重写Adpater并不能实现，ConversationListFragment是可以设置Adapter，但是继承ConversationListAdapter添加头会失败，因为官方已经封装好了的，涉及的东西较多，是无法添加成功的。所以不要偷懒，直接重写布局要来的更方便一些；

• 原理是自己写会话列表布局，那么需要的东西有哪些呢：

  • 首先我们要拿到会话列表集合
    RongIM.getInstance().getConversationList();

  • 怎么显示会话列表内容区域（这个尽量去看源码吧，不看的话也可以看我写的代码）

• Adapter写好了，加头就很简单了；
