搶紅包，先看效果圖~
實現(xiàn)自動搶紅包，解決問題有兩點:
一：如何實時監(jiān)聽發(fā)紅包的事件
二：如何在紅包到來的時候自動進(jìn)入頁面并自動點擊紅包
【zhangke3016 http://blog.csdn.net/zhangke3016】
一、如何獲取紅包到來的事件
為了獲取紅包到來狀態(tài)欄的變化，我們要用到一個類：Accessibility
許多Android使用者因為各種情況導(dǎo)致他們要以不同的方式與手機(jī)交互。
這包括了有些用戶由于視力上，身體上，年齡上的問題致使他們不能看完整的屏幕或者使用觸屏，也包括了無法很好接收到語音信息和提示的聽力能力比較弱的用戶。
Android提供了Accessibility功能和服務(wù)幫助這些用戶更加簡單地操作設(shè)備，包括文字轉(zhuǎn)語音（這個不支持中文），觸覺反饋，手勢操作，軌跡球和手柄操作。
OK,了解到這一點，那么接下來就順利點了，首先來看看Accessibility以及AccessibilityService的使用
新建一個類繼承AccessibilityService，并在AndroidManifest文件里注冊它：
<uses-permission android:name="android.permission.BIND_ACCESSIBILITY_SERVICE" />
<application>
<service android:name="com.zkhb.weixinqinghongbao.service.QiangHongBaoService"
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="@xml/qianghongbao_service_config" /></service>
</application>
在子類QiangHongBaoService里實現(xiàn)幾個重要的重載方法：
onServiceConnected() - 可選。系統(tǒng)會在成功連接上你的服務(wù)的時候調(diào)用這個方法，在這個方法里你可以做一下初始化工作，例如設(shè)備的聲音震動管理，也可以調(diào)用setServiceInfo()進(jìn)行配置工作。
onAccessibilityEvent() - 必須。通過這個函數(shù)可以接收系統(tǒng)發(fā)送來的AccessibilityEvent，接收來的AccessibilityEvent是經(jīng)過過濾的，過濾是在配置工作時設(shè)置的。
onInterrupt() - 必須。這個在系統(tǒng)想要中斷AccessibilityService返給的響應(yīng)時會調(diào)用。在整個生命周期里會被調(diào)用多次。
onUnbind() - 可選。在系統(tǒng)將要關(guān)閉這個AccessibilityService會被調(diào)用。在這個方法中進(jìn)行一些釋放資源的工作。
然后在/res/xml/qianghongbao_service_config.xml：
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android" android:accessibilityEventTypes="typeNotificationStateChanged|typeWindowStateChanged|typeWindowContentChanged"android:accessibilityFeedbackType="feedbackGeneric"android:accessibilityFlags=""android:canRetrieveWindowContent="true"android:description="@string/accessibility_description"android:notificationTimeout="100"android:packageNames="com.tencent.mm" />
二、主要關(guān)注點以及如何在紅包到來的時候自動進(jìn)入頁面并自動點擊紅包
在onAccessibilityEvent方法中監(jiān)聽狀態(tài)欄的變化，主要有：AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED、AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED、AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED
在響應(yīng)窗體以及窗體內(nèi)容變化時處理相關(guān)邏輯，獲取帶微信消息時以下代碼打開消息：
//將微信的通知欄消息打開Notification notification = (Notification) event
.getParcelableData()PendingIntent pendingIntent = notification
.contentIntenttry {pendingIntent
.send()} catch (PendingIntent
.CanceledException e) {e
.printStackTrace()}
具體代碼網(wǎng)上有很多，一般都是通過：findAccessibilityNodeInfosByText、findAccessibilityNodeInfosByViewId查找文本或者資源節(jié)點進(jìn)行點擊操作，但新版微信開紅包頁面進(jìn)行了處理，沒有文本信息，而如果采用：
（上圖截取是用的DDMS中的 UI Automator Viewer，如圖：Eclipse中:
或者在sdk的tools目錄下：
）
圖中resouces-id這種形式就可能出現(xiàn)這種情況:
在了解整個核心后,獲取事件不外乎就是通過文本與id判斷，那么就可以將文本改為圖標(biāo)方式，將id改為動態(tài)id(每次顯示都是隨機(jī)生成),這樣一來就可以提高外掛的門檻。
如何進(jìn)行規(guī)避呢，目前我想的是既然開紅包的頁面文本和ID都有可能會變，那我們能不能找個不變的進(jìn)行判斷呢，考慮過后，我覺得最可能不變的地方就是開紅包這個按鈕的位置，也就是圖中的bounds，于是在思考過后有了下面的處理:
for (
int i =
0; i < nodeInfo.getChildCount(); i++) {Rect outBounds =
new Rect();nodeInfo.getChild(i).getBoundsInScreen(outBounds);
int left_dp = px2dip(
this,
400);
int top_dp = px2dip(
this,
1035);
int right_dp = px2dip(
this,
682);
int bottom_dp = px2dip(
this,
1320);
int left_px = dip2px(
this, left_dp);
int top_px = dip2px(
this, top_dp);
int right_px = dip2px(
this, right_dp);
int bottom_px = dip2px(
this, bottom_dp);Rect mStandar =
new Rect(left_px,top_px,right_px,bottom_px);
if(mStandar.contains(outBounds)){Log.e(
"TAG",
"outBounds.left :"+outBounds.left+
";outBounds.top :"+outBounds.top+
";outBounds.right :"+outBounds.right+
";outBounds.bottom :"+outBounds.bottom);nodeInfo.getChild(i).performAction(AccessibilityNodeInfo.ACTION_CLICK);
break;}}
這里取的矩形區(qū)域要比按鈕區(qū)域稍大點，然后判斷到開紅包頁面按鈕是否在我們預(yù)先設(shè)置的區(qū)域內(nèi)，如果在，我們直接進(jìn)行點擊開紅包操作:AccessibilityNodeInfo.ACTION_CLICK。
其他比如如何防止重復(fù)搶等細(xì)節(jié)問題，也是要處理的問題。
好了，直接放下關(guān)鍵代碼，僅供參考:

AccessibilityService還可以用在智能安裝、虛擬按鍵上都有很多應(yīng)用，這樣的實踐只是給我們一種解決問題另外的一種思路，問題嘛，總還是要解決的。
