Android-具有一个布局，多个set的RecyclerView

您也需要设置

else

// if no url is found from serverif(url == null){  ((ObjectViewHolder) holder).userPostImageWrapper.setVisibility(View.GONE);  ((ObjectViewHolder) holder).userPostYoutubeImageWrapper.setVisibility(View.GONE);} else {  // Some url has found   ((ObjectViewHolder) holder).userPostImageWrapper.setVisibility(View.VISIBLE);  ((ObjectViewHolder) holder).userPostYoutubeImageWrapper.setVisibility(View.VISIBLE);}

如果要在运行时设置其可见性，请对作为列表项的每个项执行此操作。
