Here is my code:-

class ACFragment : Fragment() {

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

    }

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        val id = "ac"

        fb_ac.setOnClickListener {
            val intent = Intent(this@ACFragment, AddFunction::class.java)
            intent.putExtra("id", id)
            startActivity(intent)
        }

        return inflater.inflate(R.layout.fragment_ac, container, false)
    }
}

I want to transfer data from fragment to activity using Intent but I am unable to do it. Can Someone please help me?

CodePudding user response：

You can retrieve the id string in the AddFunction activity by calling the getStringExtra method:

override fun onCreate(savedInstanceState: Bundle) {
    ...

    val id = intent.getStringExtra("id") ?: ""
}

Also, you should change your onCreateView declaration like this:

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

    val id = "ac"

    view.findViewById<Button>(R.id.fb_ac).setOnClickListener {
        val intent = Intent(requireContext(), AddFunction::class.java)
        intent.putExtra("id", id)
        startActivity(intent)
    }

    return view 
}
