下拉布局

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_width="match_parent" 
  android:layout_height="wrap_content" 
  android:gravity="center" 
  android:orientation="vertical"> 
   
   
  <ImageView 
    android:src="@mipmap/ic_launcher" 
    android:scaleType="centerCrop" 
    android:id="@+id/item_simageview" 
    android:layout_width="match_parent" 
    android:layout_height="100dp" /> 
 
  
</LinearLayout>

刷新布局

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
  android:layout_width="match_parent" 
  android:layout_height="wrap_content" 
  android:gravity="center" 
  android:orientation="vertical"> 
   
   
  <ImageView 
    android:src="@mipmap/ic_launcher" 
    android:id="@+id/item_simageview" 
    android:layout_width="match_parent" 
    android:layout_height="100dp" /> 
 
  <TextView 
 
    android:background="@color/colorPrimary" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/item_stextview"/> 
 
 
</LinearLayout>

MultiAdapter 适配器

public class MultiAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> { 
 
 
  private Context context; 
  private List<String> list; 
 
 
  public MultiAdapter(Context context,List<String> list) { 
    this.context = context; 
    this.list = list; 
 
  } 
 
  @Override 
  public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) { 
 
    if (viewType == 0) { 
 
      View view = LayoutInflater.from(context).inflate(R.layout.layout_fitem,parent,false); 
      return new FViewHolder(view); 
 
    } else { 
      View view = LayoutInflater.from(context).inflate(R.layout.layout_sitem,false); 
 
      return new SViewHolder(view); 
 
    } 
 
 
  } 
 
 
  @Override 
  public int getItemViewType(int position) { 
    return position % 2 ; 
  } 
 
  @Override 
  public void onBindViewHolder(RecyclerView.ViewHolder holder,int position) { 
 
 
 
 
    if(holder instanceof FViewHolder){ 
 
      FViewHolder fViewHolder = (FViewHolder)holder ; 
      fViewHolder.itemStextview.setText(position+""); 
      Glide.with(context).load(list.get(position)).into(fViewHolder.itemSimageview); 
 
//      ImageLoader.getInstance().displayImage(list.get(position),fViewHolder.itemSimageview); 
 
 
    } else { 
 
      SViewHolder sViewHolder = (SViewHolder)holder ; 
      Glide.with(context).load(list.get(position)).into(sViewHolder.itemSimageview); 
 
//      ImageLoader.getInstance().displayImage(list.get(position),sViewHolder.itemSimageview); 
 
    } 
 
 
  } 
 
  @Override 
  public int getItemCount() { 
    return list.size(); 
  } 
 
 
 
  static class FViewHolder extends RecyclerView.ViewHolder{ 
    @BindView(R.id.item_simageview) 
    ImageView itemSimageview; 
    @BindView(R.id.item_stextview) 
    TextView itemStextview; 
 
    FViewHolder(View view) { 
      super(view); 
      ButterKnife.bind(this,view); 
    } 
  } 
 
  class SViewHolder extends RecyclerView.ViewHolder{ 
    @BindView(R.id.item_simageview) 
    ImageView itemSimageview; 
 
    SViewHolder(View view) { 
      super(view); 
      ButterKnife.bind(this,view); 
    } 
  } 
}
