-------------------------------------------------------------------------------- 1 | # 1.RecyclerViewLoopScrollAnimation项目介绍 2 | > 🍎 `RecyclerViewLoopScrollAnimation` 适用于Android RecyclerView的循环滚动动画的帮助类，可实现类似于老虎机抽奖，数字滚动等效果。 3 | 4 | [![](https://jitpack.io/v/xiangang/RecyclerViewLoopScrollAnimation.svg)](https://jitpack.io/#xiangang/RecyclerViewLoopScrollAnimation) [![Android CI](https://github.com/xiangang/RecyclerViewLoopScrollAnimation/actions/workflows/android.yml/badge.svg?branch=main)](https://github.com/xiangang/RecyclerViewLoopScrollAnimation/actions/workflows/android.yml) 5 | 6 | # 2. 效果展示 7 | 8 | git太大，压缩的厉害，导致帧率太低，建议下载工程运行查看实际效果。 9 | 10 | ![演示图](https://github.com/xiangang/RecyclerViewLoopScrollAnimation/blob/main/demo.gif) 11 | 12 | # 3. 使用方法： 13 | 14 | 第一步： 15 | 在你的根目录中的 build.gradle 文件中，repositories 标签下添加jitpack maven仓库： 16 | 17 | Add it in your root build.gradle at the end of repositories: 18 | 19 | ``` 20 | allprojects { 21 | repositories { 22 | ... 23 | maven { url 'https://jitpack.io' } 24 | } 25 | } 26 | 27 | ``` 28 | 若使用Gradle 7.0 ，则在setting.gradle中的dependencyResolutionManagement的repositories标签中添加： 29 | ``` 30 | dependencyResolutionManagement { 31 | repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS) 32 | repositories { 33 | ... 34 | maven { url 'https://jitpack.io' } 35 | ... 36 | } 37 | } 38 | ... 39 | 40 | ``` 41 | 42 | 第二步： 43 | 添加依赖 44 | Add the dependency 45 | 46 | ``` 47 | dependencies { 48 | implementation 'com.github.xiangang:RecyclerViewLoopScrollAnimation:v1.0.0-alpha02' 49 | } 50 | 51 | ``` 52 | 53 | # 4. 使用示例 54 | 使用实例如下： 55 | ```kotlin 56 | //创建一个RecyclerViewLoopScrollAnimation实例 57 | val recyclerViewLoopScrollAnimation = RecyclerViewLoopScrollAnimation() 58 | //创建一个Configuration 59 | val recyclerViewLoopScrollAnimationConfiguration = RecyclerViewLoopScrollAnimation.build { 60 | scrollAnimatorDuration = 4000L 61 | } 62 | //设置Configuration 63 | recyclerViewLoopScrollAnimation.setConfiguration(recyclerViewLoopScrollAnimationConfiguration) 64 | //将recyclerViewLoopScrollAnimation关联到RecyclerView 65 | recyclerViewLoopScrollAnimation.attachToRecyclerView(holder.recyclerView) 66 | //配合LooperLinearLayoutManager实现无限滚动 67 | val looperLinearLayoutManager = LooperLinearLayoutManager(context, RecyclerView.VERTICAL, false) 68 | recyclerView.layoutManager = looperLinearLayoutManager 69 | //设置滚动Action，用于滚动时返回当前显示View的Position 70 | recyclerViewLoopScrollAnimation.setRecyclerViewScrollAction(object:RecyclerViewScrollAction { 71 | override fun findFirstVisibleItemPosition(): Int { 72 | return looperLinearLayoutManager.findFirstVisibleItemPosition() 73 | } 74 | 75 | override fun findLastVisibleItemPosition(): Int { 76 | return looperLinearLayoutManager.findLastVisibleItemPosition() 77 | } 78 | }) 79 | //开始动画 80 | recyclerViewLoopScrollAnimation.start() 81 | ``` 82 | 83 | 更多用法可参考工程里的app。 84 | 85 | # 5. 其它 86 | 87 | RecyclerViewLoopScrollAnimation.Configuration配置类： 88 | 89 | ```kotlin 90 | /** 91 | * 配置 92 | */ 93 | class Configuration { 94 | /** 95 | * 是否禁止Item相应手指滑动 96 | */ 97 | var disableItemTouchListener = true 98 | 99 | /** 100 | * 第一阶段的滚动动画时长 101 | */ 102 | var scrollAnimatorDuration = 3000L 103 | 104 | /** 105 | * 第一阶段的滚动动画的插值器 106 | */ 107 | var scrollAnimatorInterpolator = AccelerateDecelerateInterpolator() 108 | 109 | /** 110 | * 是否开启弹簧动画 111 | */ 112 | var enableSpringAnimator = true 113 | 114 | /** 115 | * 第一阶段的滚动动画针对item的滚动步长（scrollBy方法的y参数） 116 | */ 117 | var scrollAnimatorScrollByYStep = 30 118 | 119 | /** 120 | * 第二阶段的弹簧动画的SpringForce 121 | */ 122 | var springAnimatorForce: SpringForce = SpringForce(0f) 123 | .setDampingRatio(SpringForce.DAMPING_RATIO_HIGH_BOUNCY) 124 | .setStiffness(SpringForce.STIFFNESS_VERY_LOW) 125 | .setDampingRatio(0.2f) 126 | .setStiffness(350f) 127 | 128 | /** 129 | * 弹簧动画的起始位置 130 | */ 131 | var springAnimatorStartValue = -50f 132 | 133 | } 134 | ``` 135 | 136 | RecyclerViewLoopScrollAnimation.build的用法为[Function literals with receiver](https://kotlinlang.org/docs/lambdas.html#function-literals-with-receiver)： 137 | 138 | ```kotlin 139 | /** 140 | * 配置 141 | */ 142 | //创建一个RecyclerViewLoopScrollAnimation实例 143 | val recyclerViewLoopScrollAnimation = RecyclerViewLoopScrollAnimation() 144 | //创建一个Configuration 145 | val recyclerViewLoopScrollAnimationConfiguration = RecyclerViewLoopScrollAnimation.build { 146 | scrollAnimatorDuration = 4000L 147 | } 148 | //设置Configuration 149 | recyclerViewLoopScrollAnimation.setConfiguration(recyclerViewLoopScrollAnimationConfiguration) 150 | 151 | ``` 152 | 153 | 扩展阅读：[你会用Kotlin实现构建者模式吗？](https://zhuanlan.zhihu.com/p/267145868) 154 | 155 | 156 | 157 | 其它接口： 158 | 159 | ``` 160 | /** 161 | * RecyclerView滚动过程中需要执行的Action 162 | */ 163 | fun setRecyclerViewScrollAction(recyclerViewScrollAction: RecyclerViewScrollAction) { 164 | this.recyclerViewScrollAction = recyclerViewScrollAction 165 | } 166 | 167 | /** 168 | * 设置滚动动画监听器 169 | */ 170 | fun setOnSpringAnimationEndListener(onScrollAnimatorListener: Animator.AnimatorListener) { 171 | this.onScrollAnimatorListener = onScrollAnimatorListener 172 | } 173 | 174 | /** 175 | * 设置弹簧动画结束监听器 176 | * 可用于动画结束后执行爆炸粒子效果 177 | */ 178 | fun setOnSpringAnimationEndListener(onAnimationEndListener: DynamicAnimation.OnAnimationEndListener) { 179 | this.onSpringAnimationEndListener = onAnimationEndListener 180 | } 181 | ``` 182 | 183 | 184 |
