Android 通过 AccessibilityService 来实现微信自动点赞功能

Manifest文件中配置service

在res下创建xml目录 创建accessibility.xml 配置service

之后在MainActivity中 查看一下是否开启无障碍模式，如果没有提醒用户去开启  当配置完毕之后 service将会自动启动 

service中代码

“com.tencent.mm:id/eii”这个id是对微信页面抓取的id  如果不了解怎么抓取 详情见monitor抓取 每次微信更新 这些id基本都会变，需要进行适配

eii：朋友圈列表整体list ID

b6e：列表用户名 ID

eho:评论点赞父及按钮

emj:已点赞人条目

eh_:点赞按钮
