方法一，经测试有效：
@Overridepublic void onBindViewHolder(final DownlaodViewHolder holder, final int position) {

          if(isVisible){
                holder.setVisibility(true);
           }else{
                holder.setVisibility(false);
           }
}

public class DownlaodViewHolder extends RecyclerView.ViewHolder{    private TextView project_package_name,main_text_title,progress_tex;    private Button file_load;    private ProgressBar progress_bar;    public DownlaodViewHolder(View itemView) {        super(itemView);        main_text_title= (TextView) itemView.findViewById(R.id.main_text_title);        project_package_name= (TextView) itemView.findViewById(R.id.project_package_name);        progress_tex=(TextView) itemView.findViewById(R.id.progress_tex);        file_load= (Button) itemView.findViewById(R.id.file_load);        progress_bar= (ProgressBar) itemView.findViewById(R.id.progress_bar);    }    public void setVisibility(boolean isVisible){        RecyclerView.LayoutParams param = (RecyclerView.LayoutParams)itemView.getLayoutParams();        if (isVisible){            param.height = LinearLayout.LayoutParams.WRAP_CONTENT;            param.width = LinearLayout.LayoutParams.MATCH_PARENT;            itemView.setVisibility(View.VISIBLE);        }else{            itemView.setVisibility(View.GONE);            param.height = 0;            param.width = 0;        }        itemView.setLayoutParams(param);    }}
方法二，未经测试：
