Java 在Recyclerview中显示捕获图像和英勇图像

我正在尝试在

Recyclerview

中显示摄像头捕获图像和胆囊图像。它工作正常，但当我拍摄第二张图像或从gallary中选择时，它会替换

Recyclerview

中的第一张图像。我想在

Recyclerview

中显示我从相机中选择或捕获的所有图像

适配器代码：

private ArrayList<String> imageslist=new ArrayList<>();
private Activity activity;

public AttachDocAdapter(Activity activity,ArrayList<String> imageslist)
{
    this.activity=activity;
    this.imageslist=imageslist;
}

public class MyViewHolder extends RecyclerView.ViewHolder{

    ImageView img_document;
    CitiTextView txt_deleteimage;
    public MyViewHolder(View itemView) {
        super(itemView);
        img_document=itemView.findViewById(R.id.img_document);
        txt_deleteimage=itemView.findViewById(R.id.txt_delete);
    }
}
@Override
public AttachDocAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemview= LayoutInflater.from(parent.getContext()).inflate(R.layout.rc_img_attach_layout,parent,false);
    return new MyViewHolder(itemview);
}

@Override
public void onBindViewHolder(AttachDocAdapter.MyViewHolder holder, int position) {
    Glide.with(activity).load(imageslist.get(position)).into(holder.img_document);
    holder.txt_deleteimage.setOnClickListener(view -> removeItem(holder.getAdapterPosition()));
}

@Override
public int getItemCount() {
    if (imageslist==null)
    {
        return 0;
    }return imageslist.size();
}

    this.imageslist = imageslist;
    notifyDataSetChanged();
}

}
   }

公共类AttachDocAdapter扩展了RecyclerView.Adapter{
私有ArrayList imageslist=新ArrayList（）；
私人活动；
public AttachDocAdapter（活动活动，ArrayList imageslist）
{
这个。活动=活动；
this.imageslist=imageslist；
}
公共类MyViewHolder扩展了RecyclerView.ViewHolder{
ImageView img_文件；
CitiTextView txt_deleteimage；
公共MyViewHolder（查看项目视图）{
超级（项目视图）；
img_document=itemView.findviewbyd（R.id.img_document）；
txt_deleteimage=itemView.findViewById（R.id.txt_delete）；
}
}
@凌驾
public AttachDocAdapter.MyViewHolder onCreateViewHolder（视图组父级，int-viewType）{

当我点击TakeCamera时，三星S5上什么也没有发生。

attachDocAdapter.updateList（documentlist）这是多余的，因为每次拾取新映像时都要创建新适配器。需要查看
onCreate
和
onStart
活动代码。
