Android列表点击事件定义的一些思考

// 声明接口
interface OnItemClickListener {
    fun onItemClick(itemView: View?, pos: Int, itemId: Long)
}

//设置set方法
fun setOnItemClickListener(onItemClickListener: OnItemClickListener) {
    mClickListener = onItemClickListener
}

adapter.setOnItemClickListener(object :BaseVastBindingAdapter.OnItemClickListener{
    override fun onItemClick(itemView: View?, pos: Int, itemId: Long) {
        if (pos == 0) {
            //Something do when pos is equal to 0
        }else if (pos == 1) {
            //Something do when pos is equal to 1
        }else{
            
        }
    }
})

class VastSwipeMenuItem @JvmOverloads constructor(
    private val context: Context,
    val title: String = context.resources.getString(R.string.default_slide_item_title),
    val icon: Drawable? = ContextCompat.getDrawable(context, R.drawable.ic_null),
    val background: Drawable? = ContextCompat.getDrawable(context, R.drawable.default_menu_item_background),
    val titleColor: Int = ContextCompat.getColor(context, R.color.default_menu_item_title_color),
    val clickEvent: ((VastSwipeMenuItem, Int) -> Unit)? = null
) {
	// 具体实现
}

//声明model
val deleteItem = VastSwipeMenuItem(this@SlideActivity)
//定义点击事件
deleteItem.setClickEvent { item: VastSwipeMenuItem, position: Int ->
    run {
        Toast.makeText(this@SlideActivity, "${item.title} $position", Toast.LENGTH_SHORT)
            .show()
    }
}

ListItemView.setOnClickListener {
	//item为根据pos获取到的
    item.clickEvent?.let { it1 -> it1(item,position) }
}
