新鮮出爐的搶紅包神器
前提:實(shí)現(xiàn)一個微信自動搶紅包并不是很難胯甩，原理就是利用android的輔助功能，監(jiān)聽一下窗口變化堪嫂，找到對應(yīng)控件ID偎箫，模擬點(diǎn)擊。寫好一個service服務(wù)類即可完成皆串。但上手會發(fā)現(xiàn)這其中還是有很多問題的淹办，所以我們主要是適配版本解決問題。
一恶复、問題
關(guān)于搶紅包神器的文章也很多怜森，但使用起來效果卻不佳速挑，總結(jié)一下會有以下幾個問題 (看看是不是就是你們遇到的問題):
-
1. 紅包來源
大多數(shù)搶紅包神器只適配了從通知欄進(jìn)入的紅包 也就是微信在后臺 此時來了紅包，監(jiān)聽通知欄副硅，然后點(diǎn)進(jìn)去【搶】姥宝。但是事實(shí)上我認(rèn)為還需要適配兩個場景，一個是在聊天列表頁來紅包恐疲，一個是在好友會話頁面來了紅包腊满。
-
2. 微信版本更新，搶紅包神器紅能就不能用了
這個就是需要各個版本進(jìn)行適配 因?yàn)槲⑿琶扛掳姹九嗉海總€控件的id會發(fā)生變化碳蛋，類名有時候甚至都會混淆，改變省咨。所以當(dāng)類名肃弟、id名稱發(fā)生改變時，程序找id為null零蓉，也就沒有辦法繼續(xù)操作點(diǎn)擊笤受，從而導(dǎo)致?lián)尲t包神器功能失效。
-
3. 卡在【拆】的頁面不繼續(xù)
關(guān)于這個問題有以下發(fā)生的可能壁公，第一種就是【拆】這個button的id發(fā)生了變化感论，第二種是手機(jī)版本大于21，在搶紅包這個頁面可能存在window嵌套紊册，不能單單在getRootInActiveWindow 查找比肄，需要對21前和21后的版本進(jìn)行適配。親測有效囊陡。
二芳绩、解決方案
-
1. 紅包來源問題
若想實(shí)現(xiàn)在聊天列表頁和好友會話頁面的紅包監(jiān)聽，需要我們監(jiān)聽窗口內(nèi)容變化撞反，也就是AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED妥色，當(dāng)監(jiān)聽到窗口內(nèi)容變化時做相應(yīng)的處理。
-
2. 適配微信版本
本地適配遏片，存放在一個靜態(tài) map中 key存放微信版本 value存放一個需要適配的id合集對象嘹害。然后在服務(wù)開始前判斷當(dāng)前手機(jī)安裝微信版本，然后去本地map中取出相應(yīng)的id合集吮便。這樣使用map存儲版本號以及需要適配的id值來做兼容笔呀。或是直接適配最新的版本髓需，用戶版本過低许师，提示升級。
-
3.拆紅包
手機(jī)版本21前后做適配
三、了解android輔助功能Accessibility
AccessibilityServiceInfo
AccessibilityService
AccessibilityManager
AccessibilityEvent
Build accessibility services
AccessibilityService
AccessibilityServiceInfo
AccessibiliyEvent
AccessibilityManager
四微渠、需要適配的對象（id名稱搭幻、class名稱等）
我們把需要適配的對象起名為WxChatTag 云控更新（構(gòu)建json）或本地靜態(tài)map存儲。
public static class WxChatTag implements Serializable {
//4個Activity名字
private String ChatListClassName;//聊天列表頁
private String ConversationClassName;//會話頁面
private String PopOpenRedPacketClassName;//彈出開紅包的頁面
private String MoneyDetailClassName;//紅包領(lǐng)取詳情頁面
//id
private String OpenRedPacketButtonId;//拆紅包的id
private String MoneyDetailTextId;//紅包詳情頁的錢數(shù)id
//會話詳情頁
private String ConversationPageListViewId;//會話頁面的listview的id
private String ConversationPageRedPacketItemId;//會話頁面紅包View的id
private String ConversationPageRecentMsgId;//會話頁面最新消息的id
//聊天記錄列表頁面
private String ChatListPageItemId;//聊天列表頁面Item的id
private String ChatListPageRedHintId;//聊天列表頁紅色圓點(diǎn)提示view的id
private String ChatListPageKeyTextId;//聊天列表頁新消息信息text的id
private String KeySearchName;//會話列表頁面查找紅包的關(guān)鍵詞 領(lǐng)取紅包
//getter setter
}
關(guān)于class name名字獲取的技巧 【adb命令】
adb shell dumpsys activity | grep "mFocusedActivity" 打印棧頂當(dāng)前activity
關(guān)于id對應(yīng)情況如下圖示
MoneyDetailTextId
ConversationPageRedPacketItemId
ConversationPageListViewId
ConversationPageRecentMsgId
OpenRedPacketButtonId
ChatListPageItemId;
ChatListPageKeyTextId
ChatListPageRedHintId
五逞盆、簡易流程圖
以下為我的搶紅包神器的主要流程圖 大家作為參考檀蹋。
為了適配微信版本，首先要判斷當(dāng)前用戶的微信版本和你適配的微信版本是否相同纳击。然后進(jìn)行自定義操作续扔。你可以本地map存儲取值，也可以動態(tài)適配焕数，網(wǎng)絡(luò)請求纱昧。
監(jiān)聽onAccessibilityEvent
監(jiān)聽通知欄
監(jiān)聽到通知欄的后續(xù)操作
監(jiān)聽到窗口變化
首先判斷當(dāng)前activity 一共有四個activity窗口需要我們做處理，其他不做處理堡赔。
監(jiān)聽窗口變化
監(jiān)聽內(nèi)容變化
這一部的主要目的就是實(shí)現(xiàn)在聊天列表頁和好友會話頁面的紅包監(jiān)聽识脆。
監(jiān)聽內(nèi)容變化
