Android teaches you how to make app home page (pull-down refresh and automatic loading)

1、 Overview

As a programmer with three years of Android development experience, I'm going to practice the home page function of an app with you today. This home page is still very common in our daily contact. Although the page is simple, there are still a lot of function points involved. If the code is insufficient, I hope all my colleagues can give me some advice. Development library used in the page: the whole homepage architecture uses lrecyclerview, including drop-down refresh and automatic loading functions

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

The infinite loop rotation chart uses convenientbanner, and the effect is still very smooth. You can also modify the transition animation according to your own needs

compile 'com.bigkoo:convenientbanner:2.0.5'

The glide image library is used for image loading. The method inside is to encapsulate the network request. The dependency is okhttp. The open source library okgo is used

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

The others are the nine palaces grid

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

Automatically annotate the butterknife library, and so on

3、 Core code

Lrecyclerview is used as the main framework, and the rotation map and classified grid list are placed in the index as headers_ Header.xml layout file.
