如何从一个片段中开始的活动? [英] How do I start an activity from within a Fragment?
问题描述
我有一组 FragmentActivity
里面的标签,每个持有自己的片段。当我试图通过 onClickListener
,并使用 startActivity(myIntent)
方法来启动一个新的活动从片段中,我的应用程序的力量关闭。
I have a set of tabs inside of a FragmentActivity
that each hold their own fragment. When I tried to start a new activity from within that fragment via an onClickListener
, and using the startActivity(myIntent)
method, my application force closes.
在东张西望了一会儿,我发现了一个参考或两个名为方法 startActivityFromFragment
,但摸索了一个小时左右,我找不到任何后如何使用它,或者这是否说明或例子是我应该使用。
After looking around for a while, I found a reference or two to a method called startActivityFromFragment
, but after searching around for an hour or so I can't find any explanations or examples of how to use it or whether this is what I should be using.
我猜我问的是是否有从活动启动一个新的活动,并从片段推出一个新的活动有什么区别,如果是的话,需要什么来实现?
I guess what I'm asking is whether there is any difference between launching a new activity from an activity, and launching a new activity from a fragment, and if so, what do I need to implement?
推荐答案
您应该 getActivity()做到这一点。startActivity(myIntent)
