**前言，一天在点外卖的时候，注意到饿了么列表页的滑动效果不错，但是觉得其中的手势滑动还是挺复杂的，正好又碰到了在熟悉Touch事件的理解当中，所以就抽空对着饿了么的列表页面尝试写写这个效果，同时增加了双列表的联动效果** 2 | ** 在实现上述效果之后，用了下appbarlayout,觉得也能实现上述滑动的效果，不需要更改什么代码，体验上更好，具体可以看AndroidWidgetActivity，在这里面就是CollapsingToolbarLayout和appbarlayout的使用，完成上述的效果，可以简单看下实现的效果图，如果你们觉得满足需求了就不需要继续往下看了，如果想了解下手势点击原理的话，欢迎往下看提点意见：**

![image](https://github.com/WelliJohn/StickScrollView/blob/master/imgs/%E4%BB%BF%E9%A5%BF%E4%BA%86%E4%B9%88%E5%88%97%E8%A1%A8%E9%A1%B5.gif?raw=true) 8 | 9 | 10 | ## 2.引入 11 | ``` 12 | allprojects { 13 | repositories { 14 | jcenter() 15 | maven { url "https://jitpack.io" } 16 | } 17 | } 18 | 19 | dependencies { 20 |    com.github.WelliJohn:StickScrollView:1.1.7 21 | } 22 | ``` 23 | 24 | ## 3.界面的布局说明 25 | ``` 26 | 30 | 31 | 38 | //这里是header部分，可以随便自定义 39 | 40 | 41 | 46 | 47 | 54 | 55 | 59 | 60 | 61 | 62 | ``` 63 | 比如我们看到的仿饿了么的列表页界面，我们就需要在ViewPager设置Fragment，fragment中是左右两个列表，看下fragment的xml设置： 64 | ``` 65 | 66 | 71 | 72 | 78 | 79 | 85 | 86 | ``` 87 | 88 | ## 4.java代码必要设置 89 | ``` 90 | mStickScrollView.setContentView(mLLStickList);//这个是必须的，mLLStickList就是你想到这个布局再滑动就是下面列表滑动的部分了。 91 | mStickScrollView.setSuspensionView(mViewBottom);//这个是底部的悬浮布局，如果没有可以不设置 92 | ``` 93 | 94 | ## 5.注意事项 95 | * ScrollViewWithStickHeader内部目前支持放置ViewPager，ScrollView，RecyclerView，WebView 96 | * ScrollView，RecyclerView，WebView需要对应使用ChildScrollView，ChildRecyclerView，ChildWebView 97 | * 我们在使用的时候，需要调用mStickScrollView.setContentView(mContentView);mLLStickList就是我们需要StickHeader+列表的部分，如果你没有StickHeader的话，那么直接设置列表进来也可以，总之，你想滑动到哪个位置接下来滑动就是单纯下面的部分滑动，那你就把下面的View整体设置为mContentView。刚刚那个的ContentView是id为ll_stick_list的View。 98 | * 另外在这里ScrollViewWithStickHeader增加autoscroll属性，默认是关闭的，如果autoscroll:true的话，在我们手指放开的时候，contentView会判断是否自动滑动到顶部还是隐藏不见。 99 | * 暂不支持weight的使用，因为weight会进行二次绘制，所以如果要实现底部bottom的话，请用RelativeiLayout 100 | * 如果是用RecyclerView的话，LinearLayoutManager需要继承NoSlideLinearLayoutManager,GridLayoutManager需要继承NoSlideGridLayoutManager，new NoSlideLinearLayoutManager(context)。 101 | 102 |
