First of all i am a newbie.I am developing an app Which has a viewpager and fragments in it,but later i decided to put lists in the fragments so i had to change them into Listfragments so i had to change the adpaters a bit,and now its not working and now i am totally confused that which adapter should extend what.
首先,我是一个新手。我正在开发一个应用程序,其中有一个viewpager和片段,但后来我决定将列表放入片段,所以我不得不将它们更改为Listfragments,所以我不得不改变adpaters,现在它不工作,现在我完全混淆哪个适配器应该扩展什么。
initially i had a Viewpager adapter which extends fragmentpageadapter(should it extend any kind of listfragment pageadapter)
最初我有一个Viewpager适配器,它扩展了fragmentpageadapter(它应该扩展任何类型的listfragment pageadapter)
and i have another customadapter which extends base adapter(custom adapter because i want a custom listview in the fragments). thanx in advance.
我有另一个customadapter扩展基本适配器(自定义适配器,因为我想在片段中的自定义列表视图)。提前。

ListView (and by extension ListFragment) doesn't care what your adapter is as long as it conforms to the ListAdapter interface, which yours does if it extends BaseAdapter. There are some other Adapter implementations in the SDK for simple use cases, you can explore them on your own or look at the ApiDemos sample application.
ListView(以及扩展名为ListFragment)并不关心你的适配器是什么,只要它符合ListAdapter接口,如果扩展BaseAdapter你就会这样做。 SDK中有一些其他适配器实现用于简单的用例,您可以自己探索它们或查看ApiDemos示例应用程序。
Similarly, ViewPager only cares that you provide it something that extends PagerAdapter, which FragmentPagerAdapter does.
同样,ViewPager只关心你为它提供扩展PagerAdapter的东西,FragmentPagerAdapter就是这样做的。
