RecyclerView 클릭 이벤트 적용

 

 

Adapter에 리스터 인터페이스 추가

private lateinit var itemClickListener : OnItemClickListener

interface OnItemClickListener {
    fun onClick(v: View, position: Int, item : CalendarDay)
}

fun setItemClickListener(onItemClickListener : OnItemClickListener) {
    this.itemClickListener = onItemClickListener
}

 

 

 

onBindViewHolder에 setOnclickListener 추가

override fun onBindViewHolder(holder: CalendarViewHolder, position: Int) {
    
    ...

    // 클릭 이벤트
        holder.binding.itemReadIbtn.setOnClickListener {
            itemClickListener.onClick(it, position, dayList[position])
        }
    
}

 

 

Activity 혹은 Fragment에 setItemClickListener를 호출하고 OnItemClickListener를 익명 개체로 넘김

//클릭 이벤트
calendarAdapter.setItemClickListener(object: CalendarAdapter.OnItemClickListener{
    override fun onClick(v: View, position: Int, item : CalendarDay) {
        Toast.makeText(view?.context, dayList[position].day + "일!!" , Toast.LENGTH_SHORT).show()
    }
})
