Spring实现上拉刷新和下拉加载效果

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')

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

MultiAdapter 适配器

  public MultiAdapter(Context context, List<String> list) {
    this.context = context;

  }

  @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

  }

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