My Activity is trying to create an AlertDialog which requires a Context as a parameter. This works as expected if I use:

AlertDialog.Builder builder = new Al

    Guys I got a simple cheat sheet. create a file give it any name then in it write this code

    fun Context.alertdialog(context: Context, msg: String, icon: Drawable, title:String){
        val alertDialog = AlertDialog.Builder(context)
        alertDialog.setIcon(icon)
            .setTitle(title)
            .setMessage(msg)
        alertDialog.show()
    }
    

    now when you need to show an alert dialog only use this method anywhere

    requireActivity().alertdialog(requireContext(), resources.getString(R.string.pass_title),
                    resources.getDrawable(R.drawable.pass_ic_name), "title")
    

    Goodluck for Kotlin
