[Solved] DialogFragment match_parent attribute is not working

 How to make DialogFragment match_parent

I used to make dialog using DialogFragment.

However, match_parent which is value of layout_width and layout_height attribute is not working.

With hard work and effort, I found the solution.

override fun onResume() {
    super.onResume()

    val params = dialog?.window?.attributes    //1
    params?.width = ViewGroup.LayoutParams.MATCH_PARENT
    params?.height = ViewGroup.LayoutParams.MATCH_PARENT
    dialog?.window?.attributes = params as WindowManager.LayoutParams    //2
    dialog?.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))    //3
}

1 => Get window's attributes and set LayoutParams' value

2=> Set LayoutParams to window's attributes

3=> Make dialog's background transparent
