本文实例为大家分享了Spring实现上拉刷新和下拉加载效果，供大家参考，具体内容如下

导依赖:

compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.liaoinstan.springview:library:1.3.0'
compile files('libs/glide-3.7.0.jar') 

activity_main布局

MainActivity 主类

public class MainActivity extends Activity {

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, parent, 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);
    }
  }
}
