Since your question is tagged with Material Design, i guess you're looking for the appropriate ui-element:

It's called Chip, see https://material.io/components/chips

Please note it's looking different depending on Material Design version.

}

fun setupCategories() {
    val layoutInflater = LayoutInflater.from(this)
    val chipGroup = findViewById<ChipGroup>(R.id.chip_group)
    chipGroup.removeAllViews()

    val categories = listOf("All", "
