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{}
