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

I tried this

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

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

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

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

or maybe something like

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

Your code is almost done, you just need to pass the fragment instance as the first parameter of Intent replace YourFragmentName with your fragment name after the @, bellow:

val intent = Intent (this@YourFragmentName.context, Main::class.java)
startActivity(intent)

Look at this sample bellow:

class MyFragment: Fragment(){

    override fun onActivityCreated(savedInstanceState: Bundle?) {
        super.onActivityCreated(savedInstanceState)

  • What's the exception you're getting? maybe you forgot to declare the activity in the manifest?
