Kotlin: how to open activity from fragment with button in android

How can I open a new activity with a button inside the fragment layout?.

I have tried this

override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val view: View = inflater.inflate(R.layout.fragment_home, container, false)

        button25.setOnClickListener {
            val intent = Intent (getActivity(), settingActivity::class.java)
            getActivity().startActivity(intent)
        }
        return view
    }

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

Make your button's listener after your fragment view is created, which gives callback in onViewCreated

onCreateView is called when Fragment's view is in the process of creating and you are accessing your fragment view's child before creating it.

It should be done like,

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

   button25.setOnClickListener {
      activity?.let{
      val intent = Intent (it, Main::class.java)
      it.startActivity(intent)
    }

  }
}
