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') 

activity_main布局

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"?>
