在Recyclerview中显示捕获图像和画廊图像

Question

我正在尝试显示Recyclerview中的相机拍摄图像和画廊图像。它工作正常，但是当我捕获第二张图像或从图库中选择图像时，它将替换Recyclerview中的第一张图像。我想显示我从相机中选择或捕获的Recyclerview中的所有图像。

活动代码：

public void ShowDialog() {
    final Dialog dialog = new Dialog(AttachDisputeDocActivity.this, android.R.style.Theme_Translucent_NoTitleBar);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.rc_img_dialog_layt);
    WindowManager.LayoutParams layoutParams = dialog.getWindow().getAttributes();
    layoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
    layoutParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
    layoutParams.gravity = Gravity.BOTTOM;
    layoutParams.dimAmount = 0.5f;
    dialog.getWindow().setAttributes(layoutParams);
    dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

    RelativeLayout UploadImage = dialog.findViewById(R.id.rela_upload);
    RelativeLayout TakeCamera = dialog.findViewById(R.id.rela_camera);
    UploadImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            try {
                if (ActivityCompat.checkSelfPermission(AttachDisputeDocActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                    ActivityCompat.requestPermissions(AttachDisputeDocActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE}, DspConstant.REQUEST_GALLARY_IMAGE);
                } else {
                    gallaryintent();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
            dialog.dismiss();
        }
    });


    dialog.show();
    TakeCamera.setOnClickListener(new View.OnClickListener() {

        @Override

            }
            break;

            }
            break;

}

适配器代码：

public class AttachDocAdapter extends RecyclerView.Adapter<AttachDocAdapter.MyViewHolder> {

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();
}
public void updateList(ArrayList<String> imageslist) {
    this.imageslist = imageslist;
    notifyDataSetChanged();
}
public void removeItem(int position) {
    imageslist.remove(position);
    notifyItemRemoved(position);
}
   }

当我单击TakeCamera时，三星S5没有任何反应。
