如何阻止RecyclerView顯示主行下方的空行？

我在我的應用程序中使用了Recycler視圖和卡片視圖。如何阻止RecyclerView顯示主行下方的空行？

當我設置一定高度的ImageView的它顯示了以下回收站視圖空行。

如何刪除空行？

我強調附着在下面的截圖的問題。

請找到下面的代碼。

你爲什麼要使用兩個cardviews在XML中？ –

我必須從服務器獲取兩組不同的行。 – Ramz

你想一次顯示一個或兩個？ –

確定....適配器把這個代碼....

@Override 
public void onBindViewHolder(MyViewHolder myViewHolder, final int position) { 

    myViewHolder.raw2.setVisibility(View.Gone); 
    ri = val.get(position); 
    myViewHolder.textview_women_name.setText(ri.getTitle()); 
    Picasso.with(context).load("" + ri.getImage()).into(myViewHolder.imageView_women); 
} 

class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

    CardView raw1,raw2; 
    TextView textview_women_name, textView_men, textView_des_women, textView_des_men; 
    ImageView imageView_women, imageView_men; 


    public MyViewHolder(View itemView) { 
     super(itemView); 

     textview_women_name = (TextView) itemView.findViewById(R.id.txv_women_name); 
     imageView_women = (ImageView) itemView.findViewById(R.id.img_row_women); 
     textView_des_women = (TextView) itemView.findViewById(R.id.txv_women_description); 

     textView_men = (TextView) itemView.findViewById(R.id.txv_men_name); 
     imageView_men = (ImageView) itemView.findViewById(R.id.img_row_men); 
     textView_des_men = (TextView) itemView.findViewById(R.id.txv_men_description); 

    raw1 = (CardView) itemview.findViewById(R.id.raw1); 
    raw2 = (CardView) itemview.findViewById(R.id.raw2); 

    }

或...完全刪除第二行，而不是充氣，然後隱藏它？ –
