How to set margins to a custom dialog?

Question

Does anybody knows how can I set margins to a custom dialog? I\'m asking because I\'ve a custom dialog but when displayed it stretches to fill the parent, even though I set

Answer 1

Step 1. Add the following styles

Step 2. Extend custom dialog from DialogFragment and override the following

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setStyle(STYLE_NO_TITLE, R.style.CustomStyle)
    }

    override fun onStart() {
        super.onStart()
        val dialog: Dialog? = dialog
        if (dialog != null) {
            val width = ViewGroup.LayoutParams.MATCH_PARENT
            val height = ViewGroup.LayoutParams.MATCH_PARENT
            dialog.window?.setLayout(width, height)
            dialog?.window?.setBackgroundDrawable(InsetDrawable(ColorDrawable(resources.getColor(R.color.transparent, null)), 10, 10, 10, 10))
        }
    }

You will be able to get full screen dialog fragment with margins, without the status bar or overlapping navigation icons.
