Android--抢红包神器 辅助功能Accessibility

新鲜出炉的抢红包神器

前提:实现一个微信自动抢红包并不是很难,原理就是利用android的辅助功能,监听一下窗口变化,找到对应控件ID,模拟点击。写好一个service服务类即可完成。但上手会发现这其中还是有很多问题的,所以我们主要是适配版本解决问题。

一、问题

关于抢红包神器的文章也很多,但使用起来效果却不佳,总结一下会有以下几个问题 (看看是不是就是你们遇到的问题):

大多数抢红包神器只适配了从通知栏进入的红包 也就是微信在后台 此时来了红包,监听通知栏,然后点进去【抢】。但是事实上我认为还需要适配两个场景,一个是在聊天列表页来红包,一个是在好友会话页面来了红包。

这个就是需要各个版本进行适配 因为微信每更新版本,每个控件的id会发生变化,类名有时候甚至都会混淆,改变。所以当类名、id名称发生改变时,程序找id为null,也就没有办法继续操作点击,从而导致抢红包神器功能失效。

关于这个问题有以下发生的可能,第一种就是【拆】这个button的id发生了变化,第二种是手机版本大于21,在抢红包这个页面可能存在window嵌套,不能单单在getRootInActiveWindow 查找,需要对21前和21后的版本进行适配。亲测有效。

二、解决方案

若想实现在聊天列表页和好友会话页面的红包监听,需要我们监听窗口内容变化,也就是AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED,当监听到窗口内容变化时做相应的处理。

本地适配,存放在一个静态 map中 key存放微信版本 value存放一个需要适配的id合集对象。然后在服务开始前判断当前手机安装微信版本,然后去本地map中取出相应的id合集。这样使用map存储版本号以及需要适配的id值来做兼容。或是直接适配最新的版本,用户版本过低,提示升级。

手机版本21前后做适配

三、了解android辅助功能Accessibility

AccessibilityServiceInfo
AccessibilityService
AccessibilityManager
AccessibilityEvent
Build accessibility services

AccessibilityService
AccessibilityServiceInfo
AccessibiliyEvent
AccessibilityManager

四、需要适配的对象(id名称、class名称等)

我们把需要适配的对象起名为WxChatTag 云控更新(构建json)或本地静态map存储。

public static class WxChatTag implements Serializable {
        //4个Activity名字
        private String ChatListClassName;//聊天列表页
        private String ConversationClassName;//会话页面
        private String PopOpenRedPacketClassName;//弹出开红包的页面
        private String MoneyDetailClassName;//红包领取详情页面
        //id
        private String OpenRedPacketButtonId;//拆红包的id
        private String MoneyDetailTextId;//红包详情页的钱数id
        //会话详情页
        private String ConversationPageListViewId;//会话页面的listview的id
        private String ConversationPageRedPacketItemId;//会话页面红包View的id
        private String ConversationPageRecentMsgId;//会话页面最新消息的id

        //聊天记录列表页面
        private String ChatListPageItemId;//聊天列表页面Item的id
        private String ChatListPageRedHintId;//聊天列表页红色圆点提示view的id
        private String ChatListPageKeyTextId;//聊天列表页新消息信息text的id

        private String KeySearchName;//会话列表页面查找红包的关键词 领取红包
//getter setter
}

关于class name名字获取的技巧 【adb命令】

adb shell dumpsys activity | grep "mFocusedActivity" 打印栈顶当前activity

关于id对应情况如下图示

MoneyDetailTextId
ConversationPageRedPacketItemId
ConversationPageListViewId
ConversationPageRecentMsgId
OpenRedPacketButtonId
ChatListPageItemId;
ChatListPageKeyTextId
ChatListPageRedHintId

五、简易流程图

以下为我的抢红包神器的主要流程图 大家作为参考。

为了适配微信版本,首先要判断当前用户的微信版本和你适配的微信版本是否相同。然后进行自定义操作。你可以本地map存储取值,也可以动态适配,网络请求。

监听onAccessibilityEvent

监听通知栏

监听到通知栏的后续操作

监听到窗口变化
首先判断当前activity 一共有四个activity窗口需要我们做处理,其他不做处理。

监听窗口变化

监听内容变化
这一部的主要目的就是实现在聊天列表页和好友会话页面的红包监听。

监听内容变化
