使用XRefreshView实现下拉刷新下拉加载

github上的地址：https://github.com/huxq17/XRefreshView；

简单的实现了下ListView，RecyclerView的上拉下拉：

首先依赖一下XRefresh的库：

上代码：

activity_main:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.zhihui.xrefreshview.MainActivity">   <Button       android:layout_width="match_parent"       android:layout_height="48dp"       android:text="listViewActivity"       android:textAllCaps="false"       android:onClick="listViewActivity"/>   <Button       android:layout_width="match_parent"       android:layout_height="48dp"       android:text="RecyclerViewActivity"       android:textAllCaps="false"       android:onClick="recyclerViewActivity"/></LinearLayout>

MainActivity:

package com.zhihui.xrefreshview;import android.content.Intent;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.View;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    public void listViewActivity(View view){        startActivity(new Intent(MainActivity.this,ListViewActivity.class));    }    public void recyclerViewActivity(View view){        startActivity(new Intent(MainActivity.this,LinearRecyclerViewActivity.class));    }}
