为了使列表视图具有良好的性能，您需要实现holder模式，这很容易搞砸，特别是当您想用几种不同类型的视图填充列表时。

RecyclerView烘焙了这个模式，使它更难以搞砸。它也更灵活，更容易处理不同的布局，不是直线，如网格。

我用RecyclerView工作了一点，仍然喜欢ListView。

当然，它们都使用ViewHolders，所以这不是一个优势。 RecyclerView在编码方面更加困难。 RecyclerView不包含页眉和页脚，所以它是一个减号。 ListView不需要创建ViewHolder。如果你想要一个带有分段或子标题的列表，那么创建独立的项(没有ViewHolder)是个好主意，这样更容易，也不需要单独的类。

ListView是RecyclerView的祖先。有很多事情ListView没有做，或者做得不好。如果您要收集ListView的缺点，并通过将问题抽象到不同的域来解决问题，那么您最终会得到类似于回收器视图的东西。下面是ListViews的主要问题点:

Didn't enforce View Reuse for same item types (look at one of the adapters that are used in a ListView, if you study the getView method you will see that nothing prevents a programmer from creating a new view for every row even if one is passed in via the convertView variable) Didn't prevent costly findViewById uses(Even if you were recycling views as noted above it was possible for devs to be calling findViewById to update the displayed contents of child views. The main purpose of the ViewHolder pattern in ListViews was to cache the findViewById calls. However this was only available if you knew about it as it wasn't part of the platform at all) Only supported Vertical Scrolling with Row displayed Views (Recycler view doesn't care about where views are placed and how they are moved, it's abstracted into a LayoutManager. A Recycler can therefore support the traditional ListView as shown above, as well as things like the GridView, but it isn't limited to that, it can do more, but you have to do the programming foot work to make it happen). Animations to added/removed was not a use case that was considered. It was completely up to you to figure out how go about this (compare the RecyclerView. Adapter classes notify* method offerings v. ListViews to get an idea).

简而言之，RecyclerView是一个更灵活的ListView，尽管你可能需要做更多的编码工作。

我只是想强调RecyclerView是兼容包的一部分。这意味着每个应用程序都有自己的RecyclerView实现，而不是使用来自操作系统的特性和代码。潜在地，类似RecyclerView的功能可以成为未来操作系统的一部分，从那里使用它是有益的。例如，Harmony OS很快就会发布。将来可以更改兼容性包许可证，这可能是一种暗示。缺点总结:

许可 更大的足迹，尤其是作为许多应用程序的一部分 如果一些来自操作系统的功能可以存在，那么效率就会下降

但值得注意的是，一些功能的实现，如滑动项目，来自RecyclerView。

以上所说的一切都必须加以考虑。

主要优势:

ViewHolder在ListView中默认是不可用的。我们将在getView()中显式地创建。 RecyclerView有内置的Viewholder。
