-------------------------------------------------------------------------------- 1 | # 嵌套滚动布局 2 | 3 | * 项目地址：[Github](https://github.com/getActivity/NestedScrollLayout) 4 | 5 | * 可以扫码下载 Demo 进行演示或者测试，如果扫码下载不了的，[点击此处可直接下载](https://github.com/getActivity/NestedScrollLayout/releases/download/2.0/NestedScrollLayout.apk) 6 | 7 | ![](picture/download_demo_apk_qr_code.png) 8 | 9 | * 众所周知，WebView、LinearLayout、FrameLayout、RelativeLayout 是不支持 NestedScroll（嵌套滚动）特性的，于是就有了这个库，专门解决这一问题 10 | 11 | ![](picture/dynamic_figure.gif) 12 | 13 | #### 集成步骤 14 | 15 | * 如果你的项目 Gradle 配置是在 `7.0` 以下，需要在 `build.gradle` 文件中加入 16 | 17 | ```groovy 18 | allprojects { 19 | repositories { 20 | // JitPack 远程仓库：https://jitpack.io 21 | maven { url 'https://jitpack.io' } 22 | } 23 | } 24 | ``` 25 | 26 | * 如果你的 Gradle 配置是 `7.0` 及以上，则需要在 `settings.gradle` 文件中加入 27 | 28 | ```groovy 29 | dependencyResolutionManagement { 30 | repositories { 31 | // JitPack 远程仓库：https://jitpack.io 32 | maven { url 'https://jitpack.io' } 33 | } 34 | } 35 | ``` 36 | 37 | * 配置完远程仓库后，在项目 app 模块下的 `build.gradle` 文件中加入远程依赖 38 | 39 | ```groovy 40 | android { 41 | // 支持 JDK 1.8 及以上 42 | compileOptions { 43 | targetCompatibility JavaVersion.VERSION_1_8 44 | sourceCompatibility JavaVersion.VERSION_1_8 45 | } 46 | } 47 | 48 | dependencies { 49 | // 嵌套滚动布局：https://github.com/getActivity/NestedScrollLayout 50 | implementation 'com.github.getActivity:NestedScrollLayout:2.0' 51 | } 52 | ``` 53 | 54 | #### AndroidX 兼容 55 | 56 | * 如果项目是基于 **AndroidX** 包，请在项目 `gradle.properties` 文件中加入 57 | 58 | ```text 59 | # 表示将第三方库迁移到 AndroidX 60 | android.enableJetifier = true 61 | ``` 62 | 63 | * 如果项目是基于 **Support** 包则不需要加入此配置 64 | 65 | #### 框架用法 66 | 67 | * NestedScrollWebView 68 | 69 | ```xml 70 | 74 | ``` 75 | 76 | * NestedScrollFrameLayout 77 | 78 | ```xml 79 | 82 | 83 | 84 | ``` 85 | 86 | * NestedScrollLinearLayout 87 | 88 | ```xml 89 | 90 | 94 | 95 | 96 | ``` 97 | 98 | * NestedScrollRelativeLayout 99 | 100 | ```xml 101 | 102 | 105 | 106 | 107 | ``` 108 | 109 | * NestedScrollViewPager 110 | 111 | ```xml 112 | 116 | ``` 117 | 118 | #### 开源项目列表 119 | 120 | *
