Kotlin:在片段中打开新的Activity [英] Kotlin: open new Activity inside of a fragment

问题描述

使用按钮时如何在片段内打开新的活动?

How can I open a new Activity inside of a fragment when using a button?

我尝试过

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    LogOut_btn.setOnClickListener {
        //FirebaseAuth.getInstance().signOut()
         val intent = Intent (this, Main::class.java)
        startActivity(intent)



    }



}

val intent =意图似乎在片段中不起作用.

val intent = Intent doesn't seem to work in a fragment.

您知道如何在片段中开始新活动吗?

Any idea how I can start a new activity inside a fragment?

我很高兴收到我的每一个答复，也感谢您的帮助！

I'm thankful for every answer I get and thank you for your help!

推荐答案

由于Fragment不是Context类型，因此需要调用父级Activity:

Because Fragment is NOT of Context type, you'll need to call the parent Activity:

 val intent = Intent (getActivity(), Main::class.java)
 getActivity().startActivity(intent)

或者类似的东西

activity?.let{
    val intent = Intent (it, Main::class.java)
    it.startActivity(intent)
}
