I have this code to show menu

override fun onCreateOptionsMenu(menu: Menu): Boolean {
// Inflate the menu; this adds items to the action bar if it is present.
menuInflater.inflate(R.menu.menu_options, menu)

for ( i in 0 until menu.size() ) {
val item = menu.getItem(i)
val spanString = SpannableString(item.title.toString())
val end = spanString.length
spanString.setSpan(RelativeSizeSpan(1.8f), 0, end,
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE)
item.title = spanString
}

return true
}

when show menu active is showing naviagation bar.
