Unable to move from activity to fragment

Question

How to move from activity to fragment on button click?

private fun onClickListener() {
            profileImageView.setOnClickListener {
                val i = Intent(this, ProfileFragment::class.java)
                startActivity(i)
            }
}

Answer 1

You can't. You can either move from activity to activity or fragment to fragment. In the first case you can use the code you have implemented with

private fun onClickListener() {
        profileImageView.setOnClickListener {
            val i = Intent(this, SecondActivityWhatever::class.java)
            startActivity(i)
        }

}

otherwise you need to implement Navigation Component in order to move from fragment to fragment.

(Another option in your specific case would be using a Custom Fragment Dialog to show the profile)
