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));
    }
}
