抢红包，先看效果图~
实现自动抢红包，解决问题有两点:
一：如何实时监听发红包的事件
二：如何在红包到来的时候自动进入页面并自动点击红包
一、如何获取红包到来的事件
为了获取红包到来状态栏的变化，我们要用到一个类：Accessibility
许多Android使用者因为各种情况导致他们要以不同的方式与手机交互。
这包括了有些用户由于视力上，身体上，年龄上的问题致使他们不能看完整的屏幕或者使用触屏，也包括了无法很好接收到语音信息和提示的听力能力比较弱的用户。
Android提供了Accessibility功能和服务帮助这些用户更加简单地操作设备，包括文字转语音（这个不支持中文），触觉反馈，手势操作，轨迹球和手柄操作。
OK,了解到这一点，那么接下来就顺利点了，首先来看看Accessibility以及AccessibilityService的使用
- 新建一个类继承AccessibilityService，并在AndroidManifest文件里注册它：
<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> 在子类QiangHongBaoService里实现几个重要的重载方法：
onServiceConnected() - 可选。系统会在成功连接上你的服务的时候调用这个方法，在这个方法里你可以做一下初始化工作，例如设备的声音震动管理，也可以调用setServiceInfo()进行配置工作。
onAccessibilityEvent() - 必须。通过这个函数可以接收系统发送来的AccessibilityEvent，接收来的AccessibilityEvent是经过过滤的，过滤是在配置工作时设置的。
onInterrupt() - 必须。这个在系统想要中断AccessibilityService返给的响应时会调用。在整个生命周期里会被调用多次。
onUnbind() - 可选。在系统将要关闭这个AccessibilityService会被调用。在这个方法中进行一些释放资源的工作。
然后在/res/xml/accessibility_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、主要关注点以及如何在红包到来的时候自动进入页面并自动点击红包
在onAccessibilityEvent方法中监听状态栏的变化，主要有：AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED、AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED、AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED
在响应窗体以及窗体内容变化时处理相关逻辑，获取带微信消息时以下代码打开消息：
//将微信的通知栏消息打开
Notification notification = (Notification) event.getParcelableData();
PendingIntent pendingIntent = notification.contentIntent;
try {
pendingIntent.send();
} catch (PendingIntent.CanceledException e) {
e.printStackTrace();
}具体代码网上有很多，一般都是通过：findAccessibilityNodeInfosByText、findAccessibilityNodeInfosByViewId查找文本或者资源节点进行点击操作，但新版微信开红包页面进行了处理，没有文本信息，而如果采用：
图中resouces-id这种形式就可能出现这种情况:
在了解整个核心后,获取事件不外乎就是通过文本与id判断，那么就可以将文本改为图标方式，将id改为动态id(每次显示都是随机生成),这样一来就可以提高外挂的门槛。
如何进行规避呢，目前我想的是既然开红包的页面文本和ID都有可能会变，那我们能不能找个不变的进行判断呢，考虑过后，我觉得最可能不变的地方就是开红包这个按钮的位置，也就是图中的bounds，于是在思考过后有了下面的处理:
for (int i = 0; i < nodeInfo.getChildCount(); i++) {
//Log.e("TAG", "getViewIdResourceName :"+nodeInfo.getChild(i).getViewIdResourceName());
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;
}
}这里取的矩形区域要比按钮区域稍大点，然后判断到开红包页面按钮是否在我们预先设置的区域内，如果在，我们直接进行点击开红包操作:AccessibilityNodeInfo.ACTION_CLICK。
其他比如如何防止重复抢等细节问题，也是要处理的问题。
好了，直接放下关键代码，仅供参考:
