本文主要是介绍Android 微信红包助手功能实现解析,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
微信抢红包功能第一步是通过NotificationListenerService
监听到红包通知,然后跳转到红包页面,最后通过辅助服务AccessibilityService
来模拟点击动作,实现抢红包功能。技术难点主要是红包通知的判断和模拟点击的实现,模拟点击涉及到辅助服务相关技术。
此类实现有一个弊端,在微信的主页面上,收到消息的时候通知栏是不会通知的,所以这里不能进行解析通知栏跳转聊天页面。

1. 微信通知监听
在AndroidManifest.xml
中添加权限
<uses-permission android:name="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"/>
在启动服务前,我们应该授予App监听系统通知的权限
startActivity(new Intent("android.settings.ACTION_NOTIFICATION_LISTENER_SETTINGS"))
通知监听
private NotificationListenerService mListener = new NotificationListenerService() {@Overridepublic void onNotificationPosted(StatusBarNotification sbn) {//处理监听到的所有通知handleNotification(sbn);}@Overridepublic void onNotificationRemoved(StatusBarNotification sbn) {}
};
注册监听
try {mListener.registerAsSystemService(mContext, new ComponentName(mContext.getPackageName(), getClass().getCanonicalName()),ActivityManager.getCurrentUser());
} catch (RemoteException e) {Log.e(TAG, "Cannot register listener", e);
}
注销监听
try {mListener.unregisterAsSystemService();
} catch (RemoteException e) {Log.e(TAG, "Cannot unregister listener", e);
}
2. 微信通知解析
通过NotificationListenerService
监听通知,可以解析StatusBarNotification
来获取微信红包的相关信息,可以获取通知来自的应用包名、通知的标题和内容、通知内容点击事件中包含的信息。
private void handleNotification(StatusBarNotification sbn) {Log.e("Hongbao", "StatusBarNotification sbn: " + sbn);//StatusBarNotification: StatusBarNotification(pkg=com.tencent.mm user=UserHandle{0} id=1753384416 tag=null key=0|com.tencent.mm|1753384416|null|10162: Notification(channel=message_channel_new_id shortcut=null //StatusBarNotification中包含很多信息,主要是getPackageName和getNotificationfinal String packageName = sbn.getPackageName();//过滤微信包名if ("com.tencent.mm".equals(packageName)) {android.app.Notification notification = sbn.getNotification();//获取通知标题和内容信息Bundle extras = notification.extras;String title = extras.getString(android.app.Notification.EXTRA_TITLE);String content = extras.getString(android.app.Notification.EXTRA_TEXT);//获取通知时间long when = notification.when;//通知的点击Intent:包含重要信息PendingIntent contentIntent = notification.contentIntent;Intent intent = contentIntent.getIntent();if (intent != null && intent.getExtras() != null) {Bundle info = intent.getExtras();//包含2个重要的Key://Main_User,可用来区分是否是群红包还是个人红包,群红包带有`@chatroom`关键字//MainUI_User_Last_Msg_Type,可用来判断消息类型,红包类型值为:436207665for (String key : info.keySet()) {Object value = info.get(key);Log.e("Hongbao", "contentIntent key=" + key + " value=" + value);}int msgType = info.getInt("MainUI_User_Last_Msg_Type");String wechatId = info.getString("Main_User");Log.e("Hongbao", "contentIntent msgType=" + msgType + " isHongbaoType=" + (msgType == 436207665) + " wechatId=" + wechatId + " isGroupMessage=" + wechatId.contains("@chatroom"));}//判断是否为红包类型:主要是解析通知内容是否包含[微信红包]关键字及消息类型,还可以过滤出发消息的人String from;String message = content;Matcher matcher = Pattern.compile("^\\\\[(.*?)\\\\](.*?):(.*)").matcher(content);if (matcher.find()) {from = matcher.group(2);message = matcher.group(3);} else {if (message.contains(":")) {from = message.split(":")[0];} else {from = title;}}Log.e("Hongbao", "title=" + title + " content=" + content + " isHongbao=" + content.contains("[微信红包]"));Log.e("Hongbao", "from=" + from + " message=" + message);}
}
根据代码打印出以下日志:
// 个人红包

3. 无障碍功能模拟点击
当完成微信通知的解析后,如果是微信红包,则可以直接跳转到相应的聊天对话框
notification.contentIntent.send();
后续就通过AccessibilityService
无障碍功能模拟点击打开红包和拆开红包功能。
添加AccessibilityService服务
<serviceandroid:name=".service.HongbaoAccessibilityService"android:enabled="true"android:exported="true"android:label="@string/accessibility_name"android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" ><intent-filter><action android:name="android.accessibilityservice.AccessibilityService" /></intent-filter><meta-dataandroid:name="android.accessibilityservice"android:resource="@xml/hongbao_service_config" />
</service>
添加AccessibilityService配置信息
<?xml version="1.0" encoding="utf-8"?>
<accessibility-servicexmlns:android="http://schemas.android.com/apk/res/android"android:description="@string/accessibility_description"android:accessibilityEventTypes="typeAllMask"android:packageNames="com.tencent.mm"android:accessibilityFeedbackType="feedbackGeneric"android:notificationTimeout="100"android:accessibilityFlags="flagDefault"android:canRetrieveWindowContent="true"/>
前往开启辅助服务界面
public void goAccess() {Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);mContext.startActivity(intent);
}
模拟点击事件
public void performViewClick(AccessibilityNodeInfo nodeInfo) {if (nodeInfo == null) {return;}while (nodeInfo != null) {if (nodeInfo.isClickable()) {nodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);break;}nodeInfo = nodeInfo.getParent();}
}
查找对应文本的View
public AccessibilityNodeInfo findViewByText(String text) {return findViewByText(text, false);
}/*** 查找对应文本的View** @param text text* @param clickable 该View是否可以点击* @return View*/
public AccessibilityNodeInfo findViewByText(String text, boolean clickable) {AccessibilityNodeInfo accessibilityNodeInfo = getRootInActiveWindow();if (accessibilityNodeInfo == null) {return null;}List<AccessibilityNodeInfo> nodeInfoList = accessibilityNodeInfo.findAccessibilityNodeInfosByText(text);if (nodeInfoList != null && !nodeInfoList.isEmpty()) {for (AccessibilityNodeInfo nodeInfo : nodeInfoList) {if (nodeInfo != null && (nodeInfo.isClickable() == clickable)) {return nodeInfo;}}}return null;
}
