title: Insert a RecyclerView inside another RecyclerView
body: <p>I am creating a set of 5 cards with the style of Google Now Cards. I am focusing first with the layout in general. </p>
  
  <p>I'm using CardView and RecyclerView and what I want to achieve is something like this:</p>
  
  <p><a href="https://i.stack.imgur.com/IZ1Hn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IZ1Hn.png" alt="enter image description here"></a></p>
  
  <p>This is my CardAdapter(Also the general adapter):</p>
  
  <pre><code>public class CardAdapter extends RecyclerView.Adapter&lt;CardAdapter.cardViewHolder&gt; {
  private ArrayList&lt;Card&gt; item;
  public CardAdapter(ArrayList&lt;Card&gt; item){
      this.item = item;
  }
  
  @Override
  public cardViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
      View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_layout,parent,false);
      cardViewHolder card = new cardViewHolder(v);
      return card;
  }
  
  @Override
  public void onBindViewHolder(cardViewHolder holder, int position) {
      holder.titel.setText(item.get(position).getTitel());
      holder.card_icon.setImageResource(item.get(position).getIcon());
      holder.load_more.setText("Load more");
  }
  
  @Override
  public int getItemCount() {
      return item.size();
  }
  
  public static class cardViewHolder extends RecyclerView.ViewHolder{
      TextView titel;
      ImageView card_icon;
      RecyclerView list_content;
      TextView load_more;
      public cardViewHolder(View itemView){
          super(itemView);
           titel = (TextView)itemView.findViewById(R.id.titel);
          card_icon = (ImageView)itemView.findViewById(R.id.card_icon);
          load_more = (TextView)itemView.findViewById(R.id.loadmore);
          list_content = (RecyclerView)itemView.findViewById(R.id.list_content);
      }
  
  }}
  </code></pre>
  
  <p>This is the MensaCardAdapter(the adapter for the first card, as far as I know everycard should have a particular adapter since they all have different layouts)</p>
  
  <pre><code>public class MensaCardAdapter extends RecyclerView.Adapter&lt;MensaCardAdapter.MensaViewHolder&gt; {
  private List&lt;MensaRow&gt; items;
  
  public MensaCardAdapter(List&lt;MensaRow&gt; items) {
      this.items = items;
  }
  
  
  
  @Override
  public MensaViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
      View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.mensa_row,parent,false);
      return new MensaViewHolder(v);
  }
  
  @Override
  public void onBindViewHolder(MensaViewHolder holder, int position) {
      holder.content.setText(items.get(position).getMensa_row_content());
      holder.img.setImageResource(items.get(position).getMensa_row_img());
      holder.title.setText(items.get(position).getTitel());
  }
  
  @Override
  public int getItemCount() {
      return items.size();
  }
  
  public class MensaViewHolder extends RecyclerView.ViewHolder{
      private ImageView img;
      public TextView title;
      public TextView content;
  
      public MensaViewHolder(View itemView){
          super(itemView);
          img = (ImageView)itemView.findViewById(R.id.mensa_row_img);
          title = (TextView)itemView.findViewById(R.id.mensa_row_title);
          content = (TextView)itemView.findViewById(R.id.mensa_row_content);
      }

  <p>1- I can create the cards with no RecyclerView inside them without problems, but I have no idea how to write the activitymain class with 1 general RecyclerView and 5 independent and different RecyclerView.</p>
  
  <p>The thing is that every card has different layout and different content, I am very new to android and I really don't understand any other complicated examples</p>
  
  <p>Any help will be appreciated</p>
