Я пытаюсь сделать нижний лист с рециркуляцией просмотра с карточками. Я был в состоянии положить карты в нижней части листа, но у меня проблемы с рециркуляцией. Как показано на фотографии, он создает несколько нижних листов с карточками внутри них. Я пытался это исправить, но пока не повезло. Как сделать так, чтобы на нижнем листе были карточки с обзором переработчика? Я считаю, что проблема в Recyclerview в activity_main, но я не знаю, где его разместить.

rcv.layoutManager = LinearLayoutManager(this, RecyclerView.VERTICAL, false) as RecyclerView.LayoutManager?
rcv.adapter = adapter;

private fun configureBackdrop() {
// Get the fragment reference
val fragment = supportFragmentManager.findFragmentById(R.id.filter_fragment)
fragment?.let {
// Get the BottomSheetBehavior from the fragment view
BottomSheetBehavior.from(it.view)?.let { bsb ->
mBottomSheetBehavior = bsb
}
}
}
