搶紅包的原理都差不多，一般是用Android的輔助功能（AccessibilityService類）先監(jiān)聽通知欄事件或窗口變化事件來查找紅包關(guān)鍵字然后去模擬點(diǎn)擊或打開紅包。

下面附上源碼，程序已實(shí)現(xiàn)自動(dòng)搶紅包，鎖屏黑屏狀態(tài)自動(dòng)解鎖亮屏，Android4.X測(cè)試通過。函數(shù)具體功能請(qǐng)看詳細(xì)注釋。
注：在聊天界面收到紅包不會(huì)自動(dòng)打開，因?yàn)橥ㄖ獧跊]有消息提示從而監(jiān)聽不了，此時(shí)只需手動(dòng)點(diǎn)一下即可。其他未知情況請(qǐng)自行用LogCat調(diào)試，源碼已經(jīng)有相關(guān)的調(diào)試信息。軟件僅供學(xué)習(xí)娛樂。

AndroidManifest.xml中聲明相關(guān)服務(wù)和權(quán)限

<uses-permission android:name="android.permission.WAKE_LOCK" /> 
<uses-permission android:name="android.permission.DISABLE_KEYGUARD" /> 
<application 
android:allowBackup="true" 
android:icon="@drawable/ic_launcher" 
android:label="@string/app_name" 
android:theme="@style/AppTheme" > 
<pre name="code" class="html"><service 
android:name="com.example.test.Demo" android:enabled="true" android:exported="true" android:label="@string/app_name" android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" > <intent-filter> <action android:name="android.accessibilityservice.AccessibilityService" /> </intent-filter> <meta-data android:name="android.accessibilityservice" android:resource="@layout/accessibility_config"/></service></application>

accessibility_config.xml服務(wù)配置內(nèi)容如下

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android" 
android:accessibilityEventTypes="typeNotificationStateChanged|typeWindowStateChanged|typeWindowContentChanged" 
android:accessibilityFeedbackType="feedbackGeneric" 
android:accessibilityFlags="flagDefault" 
android:canRetrieveWindowContent="true" 
android:description="@string/desc" 
android:notificationTimeout="100" 
android:packageNames= "com.tencent.mm,com.tencent.mobileqq" />

其中description為輔助功能的描述內(nèi)容，packageNames為監(jiān)聽的程序包名，此處只監(jiān)聽微信和QQ的accessibilityEventTypes

以上所述是針對(duì)Android輔助功能AccessibilityService與搶紅包輔助的相關(guān)知識(shí)，希望對(duì)大家有所幫助。
