Android RecyclerView loads two layout methods

When the RecyclerView has a pull-down refresh, sometimes the list reflected in the design drawing has a header layout. This can be loaded through Adapter. Here we take loading two layouts as an example.

Let's take a look at Adapter's code:

import ;
import ;
import .;
import ;
import ;
import ;
import ;

import ;

import ;
import ;

public class MainListAdapter extends &lt;&gt;{
 private List&lt;Data&gt; list;
 private ArrayList&lt;ItemEntity&gt; jdList;
 private Context context;

 public MainListAdapter(List&lt;Data&gt; list,ArrayList&lt;ItemEntity&gt; jdList, Context context) {
   = list;
   = jdList;
   = context;
 }
 @Override
 public int getItemViewType(int position) {
  return (position).getShowType();
 }
 @Override
 public  onCreateViewHolder(ViewGroup parent, int viewType) {
  if(viewType==1){
   View view = (()).inflate(.layout_header_main_list,parent,false);
   return new HeaderHolder(view);
  }else{
   View view = (()).inflate(.item_list_main,parent,false);
   return new ViewHolderItem(view);
  }
 }

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

  if(holder instanceof HeaderHolder){
   final HeaderHolder headerHolder = (HeaderHolder) holder;
   //TODO implements related logic  }else if(holder instanceof ViewHolderItem){

  }
 }

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

 private class HeaderHolder extends {

  HeaderHolder(View itemView) {
   super(itemView);
  }
 }

 private class ViewHolderItem extends {

  ViewHolderItem(View itemView) {
   super(itemView);
  }
 }


}

getItemViewType() returns the current layout type of the list. When Adapter loads the layout, the alignment is judged, that is, the corresponding judgment logic is implemented in the onBindViewHolder() method.
