列表和matrixcursor之差（Android版）

问题描述

我试图让我在其中收集从网上JSON文件我的数据一个新的Andr​​oid项目。
如果我期待在互联网上，我可以看到很多在那里它们被存储在MatrixCursor收集的数据的例子。
就个人而言，我觉得它更容易（和更短/快）的所有数据存储在一个模型类的列表。
有没有为什么他们不使用列表，而不是MatrixCursor一个很好的理由，或者它们之间有什么区别呢？

I'm trying to make a new android project in which I collect my data from an online JSON file.If I look on the internet, I can see a lot of examples where they are storing the collected data in a MatrixCursor. Personally, I think it's much easier (and much shorter/faster) to store all the data in a list in a model class. Is there a good reason why they are not using Lists instead of MatrixCursor, or what are the differences between them ?

推荐答案

我也preFER有可以从JSON数据与自定义创建沿着模型类 ListAdapter 这些类。

I also prefer to have model classes that can be created from JSON data along with a custom ListAdapter for those classes.

不过，也有组件，如搜索查看明确要求在的CursorAdapter 即用于搜索建议。在这些情况下。它更容易把数据放到像光标 MatrixCursor ，传递到 SimpleCursorAdapter ，并用它做。

However, there are components such as SearchView that specifically require a CursorAdapter i.e. for search suggestions. In those cases. it's easier to put the data into a cursor like a MatrixCursor, pass that to a SimpleCursorAdapter and be done with it.
