如何一个类可以用两种不同类型的延伸，而一个类是从外部库等是内置的 [英] How a class can extend with two different classes While one class is from a external library and other is built in

问题描述

我使用SherlockActionBar库在我project.And我的类扩展一个抽象类SherlockActivity

I am using SherlockActionBar library in my project.And my class is extending an abstract class SherlockActivity

public class AllAppsInfo extends SherlockActivity{}

在这其间我想延长我的AllAppsInfo与FragmentActivity作为well.Which不允许由于Java的多重继承的疏忽造成的。

In mean while i want to extend my AllAppsInfo with FragmentActivity as well.Which is not allowed due to negligence of multiple inheritance in java.

我已经做了一些搜索，组成了解决方案，但如何在这种情况下使用呢？无论是我可以使抽象的大侦探类的接口也同样可以用片段Activity类完成
。

I have done some search, composition is the solution but how to use it in this Scenario? Neither i can make abstract Sherlock class a interface nor same be done with Fragment Activity class .

推荐答案

我已经用我的扩展类解决了这个问题的 SherlockFragmentActivity

I have solved this issue by extending my class with SherlockFragmentActivity

public class AllAppsInfo extends SherlockFragmentActivity{}
