如何修复不同项目中的重复图片？

Question

我有一个定义FlexBoxRecyclerView的RecyclerView。 我的问题是，例如，当我用一个图像创建第一个项目，并且还创建与第一个项目具有相同图像的item2时，仅添加另一张不同的图片。

我的问题：第一个第一项加倍，或者item2重复图像中的第一项。

适配器

class AdapterPostProfile
    : RecyclerView.Adapter<AdapterPostProfile.ViewHolder>() {

    private lateinit var mAdapter: PostAdapter
    private lateinit var context: Context
    private lateinit var activity: ProfileActivity
    private lateinit var list: ArrayList<ProfileActivity.DataPost>




    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        val user = list[position]
        holder.view.text_post.text = user.textL
        mAdapter = PostAdapter()
        holder.view.rec_im.adapter = mAdapter
        val layoutManager = FlexboxLayoutManager(context)
        layoutManager.flexDirection = FlexDirection.ROW
        layoutManager.justifyContent = JustifyContent.FLEX_START
        layoutManager.flexWrap = FlexWrap.WRAP
        holder.view.rec_im.layoutManager = layoutManager
        mAdapter.update(context, user.arrayPhotos!!)
    }







    class ViewHolder(val view: View) : RecyclerView.ViewHolder(view)



    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        val view = LayoutInflater.from(parent.context)
                .inflate(R.layout.item_post, parent, false)
        return ViewHolder(view)
    }

    fun update(activity: ProfileActivity, con: Context, moviesList: ArrayList<ProfileActivity.DataPost>) {
        this.context = con
        if (::list.isInitialized){
            list.addAll(moviesList)
        } else{
            list = moviesList
        }
        this.activity = activity
        notifyDataSetChanged()
    }


    override fun getItemCount() = list.size


}

数据发布

  data class DataPost(
                var textL:String? =null,
                var arrayPhotos:ArrayList<String>? = null,
                var time:String? = null,
                var ids_post:String = "")

后适配器

internal class PostAdapter : RecyclerView.Adapter<PostViewHolder>() {

    private lateinit var context: Context


    companion object {
        private var IMAGE_IDS = ArrayList<String>()
    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): PostViewHolder {
        val view = LayoutInflater.from(parent.context)
                .inflate(R.layout.viewholder_cat, parent, false)
        return PostViewHolder(view)
    }

    override fun onBindViewHolder(holder: PostViewHolder, position: Int) {
        holder.bindTo(IMAGE_IDS[position], context, position)
    }



    fun update(con: Context, moviesList: ArrayList<String>) {
        this.context = con
        IMAGE_IDS = moviesList
        notifyDataSetChanged()
    }



    override fun getItemCount() = IMAGE_IDS.size
}

PostViewHolder

internal class PostViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {

    private val imageView: ImageView = itemView.findViewById(R.id.imageview)


    internal fun bindTo(image: String, context:Context, pos:Int) {

        val lp = imageView.layoutParams
        if (lp is FlexboxLayoutManager.LayoutParams) {
            lp.flexGrow = 1f
        }
        Picasso.get().load(image).into(imageView)

    }
}
