Have to solve this question and I'm sorry for not completed question
just added this to your adapter
fun getFilter(): Filter? {
return articleFilter
}
private val articleFilter: Filter = object : Filter() {
override fun performFiltering(constraint: CharSequence?): FilterResults? {
val filteredList: MutableList<Articles> = ArrayList()
if (constraint == null || constraint.length == 0) {
filteredList.addAll(articles)
} else {
val filterPattern =
constraint.toString().toLowerCase().trim { it <= ' ' }
for (item in articles) {
if (item.title.toLowerCase().contains(filterPattern)) {
filteredList.add(item)
}
}
}
val results = FilterResults()
results.values = filteredList
return results
}
override fun publishResults(
constraint: CharSequence?,
results: FilterResults
) {
searchArticles = results.values as List<Articles>
notifyDataSetChanged()
}
}
fun setData(article: List<Articles>){
searchArticles = article
notifyDataSetChanged()
}
