有没有办法从您传递给 FireBasUI RecyclerAdapter 的 holder class 布局中删除视图？

Question

看，这是我的问题：我使用了这个 FireBaseRecyclerViewAdapter，所以我可以上传并在我的 Homefragment 中显示我的 posts。但问题来了：我有一个布局，上面显示了图片 a 和文字。但是我也希望能够在没有图像的情况下显示 posts，所以我为每个 post 声明了一个名为 posttype 的变量，如果 posttype 为 0，则它是一个文本post否则就是图片post。问题是如何从支架上完全移除图像视图？

我试过了：

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

但问题是 ImageView 仍然留在那里，只是看不见，但我希望它完全消失，你知道吗？

这是整个 PostsAdapter 的代码class快速回答会很有帮助谢谢：

哥我好笨

如果你想知道就这样做： holder.ImageViewpicture.setVisibility(View.GONE);
