7 | 8 | 前言 9 | ------- 10 | 1. 项目需要做一个以前微信下拉显示小程序的效果，结果Google~~百度~~过并没有找到很多的开源库。而且实现方式还挺复杂，或者不适用于自己(大多数为需要ListView实现) 11 | 12 | 2. 该库主要参考[这篇文章](https://www.jianshu.com/p/e409de213938) ，实现的原理大家看这篇文章就好了，感谢该Po 13 | 14 | 3. 在该篇文章的前提下，一共作出了以下修改 15 | * 把Kotlin改为了Java 16 | * 把可滑动控件的主布局改为了NestedScrollView(原文为ListView)，按照原理，你可以改为任意一个可滑动的控件(但是需要您亲自下载library修改) 17 | * 一些代码的优化，譬如 18 | * NestedScrollView的布局直接在xml里实现 19 | * 接口的添加和优化，使得更加方便 20 | 21 | 4. 需要修改更多内容的可以下载library自行修改 22 | 23 | 5. 有不妥之处请Issues指出,谢谢 24 | 25 | 26 | Usage 27 | -------- 28 | 29 | With Gradle: 30 | ```groovy 31 | implementation 'com.wenwenwen888:pullloadmoreview:1.1.0' 32 | ``` 33 | 34 | 35 | How to use（直接clone项目查看demo更加直观哦） 36 | -------- 37 | 一：xml主布局配置 38 | ```java 39 | 40 | 46 | 47 | 51 | 52 | 56 | 57 | 62 | 63 | 68 | 69 | 74 | 75 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | ``` 87 | 88 | ```java 89 | //此配置为顶部布局的背景颜色 90 | app:top_background_color="#fff" 91 | ``` 92 | 二: 头部xml的配置 93 | ```java 94 | //添加头部布局 95 | pullLoadMoreView.addHeadView(R.layout.top_layout); 96 | ``` 97 | 三：可设置回调监听 98 | ```java 99 | //添加监听滑动布局的open/close 100 | pullLoadMoreView.setViewStateListener(new PullLoadMoreView.ViewStateListener() { 101 | @Override 102 | public void onViewState(PullLoadMoreView.VIewState viewState) { 103 | if (viewState == PullLoadMoreView.VIewState.OPEN) { 104 | Toast.makeText(MainActivity.this, "Open", Toast.LENGTH_SHORT).show(); 105 | } else { 106 | Toast.makeText(MainActivity.this, "Close", Toast.LENGTH_SHORT).show(); 107 | } 108 | } 109 | }); 110 | ``` 111 | 112 | # License 113 | 114 | Copyright
