54 | 55 | /** 56 | * 给VideoSdk传递触摸事件，让其在指定坐标进行摄像头聚焦 57 | * 58 | * @param e 触摸事件 59 | */ 60 | void onTouch(MotionEvent e); 61 | } 62 | ``` 63 | 64 | 然后是 ``TouchEventHandler`` 的定义： 65 | 66 | ```Java 67 | public class CameraClickHandler extends TouchEventHandler { 68 | 69 | private boolean performClick = false; 70 | //... 71 | 72 | @Override 73 | public boolean onTouch(@NonNull CameraClickView v, MotionEvent e, boolean hasBeenIntercepted) { 74 | super.onTouch(v, e, hasBeenIntercepted); 75 | if (!isCameraFocusEnable()) { //一些特殊业务需要禁止摄像头聚焦 76 | return false; 77 | } 78 | //通过MotionEvent判断performClick是否为true 79 | switch (e.getAction()) { 80 | case MotionEvent.ACTION_DOWN: 81 | //... 82 | break; 83 | case MotionEvent.ACTION_MOVE: 84 | //... 85 | break; 86 | case MotionEvent.ACTION_UP: 87 | //... 88 | break; 89 | default: 90 | break; 91 | } 92 | 93 | if (performClick) { //认为是点击行为，调用ui的接口 94 | v.showVideoClickFocus(e.getRawX(), e.getRawY()); 95 | v.onTouch(e); 96 | } 97 | return performClick; //点击的时候消费掉触摸事件 98 | } 99 | } 100 | ``` 101 | 102 | 最后是 ``TouchEventHandler`` 与 ui 的对应的绑定 103 | 104 | ```Java 105 | public class MobileLiveVideoComponent extends Fragment implements CameraClickView{ 106 | 107 | @Override 108 | public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 109 | //... 110 | //CameraClickHandler与当前Fragment绑定 111 | TouchEventBus.of(CameraClickHandler.class).attach(this); 112 | } 113 | 114 | @Override 115 | public void onDestroyView() { 116 | //... 117 | //CameraClickHandler与当前Fragment解绑 118 | TouchEventBus.of(CameraClickHandler.class).dettach(this); 119 | } 120 | 121 | @Override 122 | public void showVideoClickFocus(float x, float y) { 123 | //todo: 展示一个黄色框ui 124 | } 125 | 126 | @Override 127 | public void onTouch(MotionEvent e) { 128 | //todo: 调用SDK的摄像头聚焦 129 | } 130 | } 131 | ``` 132 | 133 | 当用户对ui的进行手势操作时，``MotionEvent`` 就会沿着 ``TouchEventBus`` 里面的顺序进行分发。如果在 **CameraClickHandler** 之前没有别的 Handler 把事件消费掉，那么就能在 ``onTouch`` 方法进行处理，然后在 ui 作出响应。 134 | 135 | ## 事件的分发顺序 136 | 137 | 多个 ``TouchEventHandler`` 之间需要定义一个分发的顺序，最先接收到触摸事件的 Handler 可以拦截后面的 Handler。在顺序的定义上，很难固定一条绝对的分发路线，因为随着直播间模版的切换，``Fragment`` 的层级可能会产生变化。 138 | 所以 ``TouchEventBus`` 使用相对的顺序定义。每个 Handler 可以决定要拦截哪些其他的 Handler。比如要把 **CameraClickHandler** 排在其他几个Handler前面： 139 | 140 | ```Java 141 | public class CameraClickHandler extends AbstractTouchEventHandler { 142 | //... 143 | 144 | @Override 145 | public boolean onTouch(@NonNull CameraClickView v, MotionEvent e, boolean hasBeenIntercepted) { 146 | //... 147 | } 148 | 149 | /** 150 | * 定义哪些Handler需要排在我的后面 151 | **/ 152 | @Override 153 | protected void defineNextHandlers(@NonNull List>>> handlers) { 154 | //下面的Handler都会在CameraClickHandler后面，但他们之间的顺序还未定义 155 | handlers.add(CameraZoomHandler.class); 156 | handlers.add(MediaMultiTouchHandler.class); 157 | handlers.add(PreviewSlideHandler.class); 158 | handlers.add(VideoControlTouchEventHandler.class); 159 | } 160 | } 161 | ``` 162 | 163 | 每个 Handler 都会指定排在自己后面的 Handler，从而形成一张图。通过拓扑排序我们就能动态地获得一条分发路径。下图的箭头指向 “A->B” 表示A需要排在B的前面： 164 | 165 | ![拓扑排序][5] 166 | 167 | 在直播间模版切换的时候，任何一个 Handler 都可以动态地添加到这个图当中，也可以从这个图中随时移除，不会影响其他业务的正常进行。 168 | 169 | ## 嵌套的视图用 Android 系统的触摸分发 170 | 171 | 互不嵌套的 ``Fragment`` 层级才需要使用 ``TouchEventBus``，``Fragment`` 内部用 Android 默认的触摸事件分发。如下图：红色箭头部分为 ``TouchEventBus`` 的分发，按 Handler 的拓扑顺序进行逐层调用。蓝色箭头部分为 ``Fragment`` 内部 ViewTree 的分发，完全依照 Android 系统的分发顺序，即从父布局向子视图分发，子视图向父布局逐层决定是否消费。 172 | 173 | ![触摸事件分发][6] 174 | 175 | ## 使用例子 176 | 177 | 运行本工程的 ***TouchSample*** 模块，是一个使用 ``TouchEventBus`` 的简单 Demo 。 178 | 179 | ![TouchSample][7] 180 | 181 | - 单指左右滑动切换选项卡 182 | - 双指缩放中间的"Tab%_subTab%"文本框 183 | - 双指左右滑动切换背景图 184 | - 滑动屏幕左侧拉出侧边面板 185 | 186 | ui的层级：Activity -> 背景图 -> 侧边面板 -> 选项卡 -> 文本框 187 | 188 | 触摸处理的顺序：侧边面板 -> 文本缩放 -> 背景图滑动 -> 底部导航点击 -> 选项卡滑动 189 | 190 | > 这里还做了一个操作是：让底部导航点击不消费触摸事件。所以你可以在底部的导航栏区域上左右滑动，切换的是一级Tab。而在背景图区域左右滑动，切换的是二级Tab。 191 | 192 | ## 配置 193 | 194 | 1. 在项目 build.gradle 添加仓库地址 195 | 196 | ```groovy 197 | allprojects { 198 | repositories { 199 | maven { url 'https://jitpack.io' } 200 | } 201 | } 202 | ``` 203 | 204 | 2. 对应模块添加依赖 205 | 206 | ```groovy 207 | dependencies { 208 | compile 'com.github.YvesCheung.TouchEventBus:toucheventbus:1.4.3' 209 | } 210 | ``` 211 | 212 | ## 许可证 213 | 214 | Copyright 2018 YvesCheung 215 | 216 | Licensed under the Apache License, Version 2.0 (the "License");

触摸处理器

14 | *

所有需要触摸事件的业务都应该是一个独立的{@link TouchEventHandler}。比如上下滑切换直播间是一个Handler， 15 | * 左滑出现菜单是一个Handler，开播的摄像头手势缩放或者点击对焦是一个Handler，插件玩法需要触摸事件处理也是一 16 | * 个Handler等等。

17 | *

每个Handler自己定义需要拦截哪些Handler。当触摸事件发生时，TouchEventBus并不是根据View树的顺序来分发事件， 18 | * 而是根据业务的需要，逐个Handler分发。通过{@link #nextHandler()}方法给出在此业务下方的Handler列表。那么 19 | * 当前Handler就会先于它们接收到触摸事件，从而判断是否需要拦截或者放开。

20 | *

在{@link #onTouch(Object, MotionEvent, boolean)}方法写对触摸事件处理的业务。

21 | *

如果当前Handler非常的霸道，无论前面的Handler是否已经拦截处理了触摸事件，自己都还是要收到触摸事件，那么就让 22 | * {@link #forceMonitor()}返回true。
