BaseAdapteras the name suggests, is a base class for all the adapters.
BaseAdapter顾名思义，是所有适配器的基类。
When you are extending the Base adapter class you need to implement all the methods like getCount(), getId()etc.
当你扩展基本适配器类需要实现所有类的方法getCount()，getId()等等。
ArrayAdapteris a class which can work with array of data. You need to override only getview()method.
ArrayAdapter是一个可以处理数据数组的类。您只需要覆盖getview()方法。
ListAdapteris a an interface implemented by concrete adapter classes.
ListAdapter是由具体的适配器类实现的接口。
BaseAdapteris an abstract class whereas ArrayAdapterand ListAdapterare the concrete classes.
BaseAdapter是抽象类，而ArrayAdapter和ListAdapter是具体类。
ArrayAdapterand ListAdapterclasses are developed since in general we deal with the array data sets and list data sets.
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。
