是否可以从传递给FireBasUI RecyclerAdapter的Holder类布局中删除视图？

Question

看来这是我的问题：我已经使用了此FireBaseRecyclerViewAdapter，因此可以在Homefragment中上传并显示帖子。但是问题来了：我有一个布局，上面显示有图片a和文本。但我希望也能显示没有图像的帖子，所以我为每个称为posttype的帖子声明了一个变量，如果posttype为0，则它​​是文本帖子，否则是图片帖子。问题是如何完全从支架上取下imageview？

我尝试过：

        if(holder.textViewpostType.getText().equals("0")){
            holder.ImageViewpicture.setImageDrawable(null);
        }

但是问题是ImageView仍然停留在那儿并且只是不可见，但是我希望它完全消失了吗？

这是整个PostsAdapter类的代码，快速解答非常有用：

import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

import androidx.recyclerview.widget.RecyclerView;

import com.firebase.ui.firestore.FirestoreRecyclerAdapter;

import com.squareup.picasso.Picasso;

import de.hdodenhof.circleimageview.CircleImageView;

public class PostsAdapter extends FirestoreRecyclerAdapter<Posts, PostsAdapter.PostsHolder> {

    public PostsAdapter(@NonNull FirestoreRecyclerOptions<Posts> options) {
        super(options);
    }

    @Override
    protected void onBindViewHolder(@NonNull PostsHolder holder, int position, @NonNull Posts model) {
        holder.textViewdescription.setText(model.getDescription());
        holder.textViewpostType.setText(String.valueOf(model.getPostType()));
        holder.textViewtime.setText("uploaded at "+model.getTime());
        holder.textViewuid.setText(model.getUid());
        holder.textViewusername.setText(model.getUsername());
        holder.buttonlikes.setText("Likes: "+model.getLikes());
        Picasso.get().load(model.getProfileImage()).into(holder.circleImageViewprofileImage);
        Picasso.get().load(model.getPicture()).into(holder.ImageViewpicture);
        holder.textViewuid.setVisibility(View.INVISIBLE);
        holder.textViewpostType.setVisibility(View.INVISIBLE);
        if(holder.textViewpostType.getText().equals("0")){
            holder.ImageViewpicture.setImageDrawable(null);

        }
    }

    @NonNull
    @Override
    public PostsHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.posts_layout, parent, false);
        return new PostsHolder(v);
    }

    class PostsHolder extends RecyclerView.ViewHolder {
        TextView textViewdescription, textViewpostType, textViewtime, textViewuid, textViewusername;
        Button buttonlikes;
        ImageView ImageViewpicture;
        CircleImageView circleImageViewprofileImage;

        public PostsHolder(@NonNull View itemView) {
            super(itemView);
            textViewdescription = itemView.findViewById(R.id.post_description);
            textViewpostType = itemView.findViewById(R.id.post_postType);
            textViewtime = itemView.findViewById(R.id.post_uploadTime);
            textViewuid = itemView.findViewById(R.id.post_userUID);
            textViewusername = itemView.findViewById(R.id.post_userName);
            buttonlikes = itemView.findViewById(R.id.post_likes);
            ImageViewpicture = itemView.findViewById(R.id.post_image);
            circleImageViewprofileImage = itemView.findViewById(R.id.post_profileImage);
        }
    }
}

兄弟，我很笨

如果您想知道，只需这样做：holder.ImageViewpicture.setVisibility（View.GONE）;
