RecyclerView - CardViews在滾動時互相重疊（如何將多行添加到單個CardView？）

整個佈局設置如下 - 一個RecyclerView包含多個卡片視圖，每個CardView可以有多行精確的LinearLayouts鍵入（但具有不同的數據）。RecyclerView - CardViews在滾動時互相重疊（如何將多行添加到單個CardView？）

一切工作正常，除了當我向下或向上滾動時，卡片開始隨機與其他卡片重疊。

下面的代碼：

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> implements View.OnClickListener{ 

    Context context; 

    public MyAdapter(Context context) 
    { 
     this.context = context; 
    } 

    @Override 
    public int getItemCount() { 
     return 20; 
    } 

    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 

     try { 

      LinearLayout.LayoutParams contentParams = new LinearLayout.LayoutParams(100, 100); 

      LayoutInflater inflater = LayoutInflater.from(context); 

      LinearLayout ll_parent = (LinearLayout) inflater.inflate(R.layout.parent_linearlayout, null, false); 
      NetworkImageView networkImageView = new NetworkImageView(context); 
      String URL = "https://www.google.co.in/images/branding/product/ico/googleg_lodp.png"; 
      networkImageView.setImageUrl(URL, VolleySingleton.getInstance(context).getImageLoader()); 
      networkImageView.setLayoutParams(contentParams); 
      networkImageView.setPadding(20, 20, 20, 20); 

      TextView tv_card_title = new TextView(context); 
      tv_card_title.setPadding(20, 20, 20, 20); 

      LinearLayout ll_title = new LinearLayout(context); 

      ll_title.setOrientation(LinearLayout.HORIZONTAL); 

      ll_title.addView(networkImageView); 
      ll_title.addView(tv_card_title); 
      ll_title.setPadding(20, 20, 20, 20); 

      ll_parent.addView(ll_title); 

      for (int j = 0; j < getItemCount(); j++) 
      { 
       LinearLayout ll_children = (LinearLayout) inflater.inflate(R.layout.child_views, null, false); 

       Button bt_delete = (Button) ll_children.findViewById(R.id.bt_delete); 
       bt_delete.setTag("card no: " + (position+1) + " Iteration: " + (j+1)); 
       bt_delete.setOnClickListener(this); 
       Button bt_edit = (Button) ll_children.findViewById(R.id.bt_edit); 
       bt_edit.setTag("card no: " + (position + 1) + " Iteration: " + (j + 1)); 
       bt_edit.setOnClickListener(this); 

       TextView tv_abc = (TextView)ll_children.findViewById(R.id.tv_abc); 
       tv_abc.setText("ABC"); 
       tv_abc.setTypeface(null, Typeface.BOLD); 

       tv_card_title.setText("ABC"); 
       tv_card_title.setTypeface(null, Typeface.BOLD); 

       NetworkImageView iv_Image = (NetworkImageView)ll_children.findViewById(R.id.iv_Image); 

       iv_profileImage.setImageUrl(URL, VolleySingleton.getInstance(context).getImageLoader()); 
       ll_parent.addView(ll_children); 
      } 
      holder.cardView.addView(ll_parent); 

     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 

    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) { 
     View itemView = LayoutInflater. 
       from(viewGroup.getContext()). 
       inflate(R.layout.grandparent_cardview, viewGroup, false); 

     return new ViewHolder(itemView); 
    } 

    @Override 
    public void onClick(View v) { 
     switch (v.getId()) 
     { 
      case R.id.bt_delete: 

       break; 

      case R.id.bt_edit: 

       break; 
     } 
    } 

    public static class ViewHolder extends RecyclerView.ViewHolder { 

     CardView cardView; 

     public ViewHolder(View v) 
     { 
      super(v); 
      cardView = (CardView) v.findViewById(R.id.cv); 
     } 
    } 
}

出了什麼問題上面的代碼？有沒有更好的方法將多行（同一類型）添加到單個CardView？
