  1. 我作为消息列表, 在recyclerView里面使用的时候, 内存会上涨非常厉害, 而且释放很慢, 由于一直要刷drawable, 所以CPU的使用情况也很高.
  2. 没有办法在item里面动态去添加gif, 必须要先把gif初始化出来以后才能使用

第一种情况是不是每显示一个Drawable就创建一个？没做缓存？demo中有在RecyclerView中的用法，相同的Drawable不会重复创建
在Item中创建Drawable应该也是可以的，但是这种情况感觉性能问题会比较严重，把Drawable创建出来和数据绑定在一起，应该会比根据数据动态创建Drawable更节约资源一些
如果可以的话能否贴下使用的代码，我来看看是哪有问题
