Android手把手教大家制作APP首頁（下拉刷新、自動加載）

一、概述

作為一名三年Android開發經驗的程序員，今天和大家一起實戰一款APP的首頁功能，這個首頁在我們平時接觸中還是很常見的，雖然頁面簡單，但是裡面涉及的功能點還是挺多的。代碼如有不足的還望各路同仁指點一二。
頁面中使用的開發庫：
整個首頁架構使用的是LRecyclerView，包含下拉刷新和自動加載功能

compile 'com.github.jdsjlzx:LRecyclerView:1.3.3'

無限循環輪播圖使用的是convenientbanner，效果還是很順暢的，還可以根據自己的需要修改過渡動畫

compile 'com.bigkoo:convenientbanner:2.0.5'

圖片加載使用的是glide圖片庫，裡面的方法是自己封裝的
網絡請求依賴是okhttp，使用的開源庫okgo

compile 'com.lzy.net:okgo:2.1.4'

其他的還是九宮格圖

compile 'com.lzy.widget:ninegridview:0.2.0'

自動注解butterknife庫等等

二、實現效果圖

1.首頁展示輪播圖

2.下拉刷新

3.自動加載

4.cardview水波紋動畫

三、核心代碼

LRecyclerView作為主框架，輪播圖以及分類網格列表作為header放在index_header.xml布局文件下。
