问题描述

你能告诉我 ArrayAdapter 、 BaseAdapter 和 ListAdapter 之间的区别吗.

Could you please tell me difference between ArrayAdapter , BaseAdapter and ListAdapter.

推荐答案

BaseAdapter 顾名思义，是所有适配器的基类.

BaseAdapter as the name suggests, is a base class for all the adapters.

当您扩展 Base 适配器类时，您需要实现所有方法，例如 getCount()、getId() 等.

When you are extending the Base adapter class you need to implement all the methods like getCount(), getId() etc.

ArrayAdapter 是一个可以处理数据数组的类.您只需要覆盖 getview() 方法.

ListAdapter 是由具体的适配器类实现的接口.

ListAdapter is a an interface implemented by concrete adapter classes.

BaseAdapter 是抽象类，而 ArrayAdapter 和 ListAdapter 是具体类.

BaseAdapter is an abstract class whereas ArrayAdapter and ListAdapter are the concrete classes.

ArrayAdapter 和 ListAdapter 类的开发是因为通常我们处理数组数据集和列表数据集.

ArrayAdapter and ListAdapter classes are developed since in general we deal with the array data sets and list data sets.
