微信自动抢红包

微信自动抢红包，目前只适配了6.3.32版本的，在android studio上导入，运行程序后点击开始检测，如果手机没有开启无障碍服务，则会调到设置页面进行打开无障碍服务，该app主要是用到了AccessibilityService 界面的ui控件的检测使用的是Google自带的uiautomatorviewer。

打开服务后监听三种状态 ：

AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED  和 AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED 和 

AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED 具体的代码如下：

switch (eventType) {
    //获取通知栏事件
    case AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED:
        if (isScreenBlock) {
            wakeLock();
        }
        List<CharSequence> text = event.getText();
        if (!text.isEmpty()) {
            for (CharSequence sequence : text) {
                String message = String.valueOf(sequence);
                if (message.contains("微信红包")) {
                    openNotify(event);
                }
            }
        }
        break;
    case AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED:
        openHongBao(event);
        break;
    case AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED:
        findHongBao(event);
        break;
}

if (event.getParcelableData() == null || !(event.getParcelableData() instanceof Notification)) {
    return;
}
Notification notification = (Notification) event.getParcelableData();
PendingIntent contentIntent = notification.contentIntent;
try {
    contentIntent.send();
} catch (PendingIntent.CanceledException e) {
    e.printStackTrace();
}

System.out.println("evenClass-----" + event.getClassName());
if ("com.tencent.mm.plugin.luckymoney.ui.LuckyMoneyReceiveUI".equals(event.getClassName())) {
    // 拆红包界面
    getPacket(this);;
} else if ("com.tencent.mm.plugin.luckymoney.ui.LuckyMoneyDetailUI".equals(event.getClassName())) {
    // 拆完红包后，看红包金额的界面
    getMoney();
} else if ("com.tencent.mm.ui.LauncherUI".equals(event.getClassName())) {
    // 聊天界面
    openPacket(event);
}

点击红包

private void openPacket(AccessibilityEvent event) {
    System.out.println("openPacket----");
    AccessibilityNodeInfo rootInActiveWindow = getRootInActiveWindow();
    if (rootInActiveWindow == null) {
        return;
    }
    List<AccessibilityNodeInfo> listPacket = rootInActiveWindow.findAccessibilityNodeInfosByText("领取红包");
    if (listPacket != null) {
        for (int i = listPacket.size() - 1; i >= 0; i--) {
            AccessibilityNodeInfo parent = listPacket.get(i).getParent();
            if (parent != null) {
                PerformClickUtils.performClick(parent);
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                if (!"com.tencent.mm.plugin.luckymoney.ui.LuckyMoneyReceiveUI".equals(event.getClassName())) {
                    PerformClickUtils.performBack(this);
                    return;
                }
            }
        }
    }

拆红包 ：

private void getPacket(AccessibilityService accessibilityService) {
    AccessibilityNodeInfo rootInActiveWindow = getRootInActiveWindow();
    if (rootInActiveWindow == null) {
        return;
    }
    //若出现 “该红包已超过24小时。如已领取，可在“我的红包”中查看" 则直接返回
    List<AccessibilityNodeInfo> back = rootInActiveWindow.findAccessibilityNodeInfosByViewId(hongbao_expire);
    if (back != null) {
        List<AccessibilityNodeInfo> nodeInfoId = rootInActiveWindow.findAccessibilityNodeInfosByViewId(hongbao_expire_close);  //关闭ID
        if (nodeInfoId != null && !nodeInfoId.isEmpty()) {
            PerformClickUtils.findViewIdAndClick(this, hongbao_expire_close);
        } else {
            PerformClickUtils.performBack(this);
        }
        PerformClickUtils.findTextAndClick(this, "聊天信息");
    }
    List<AccessibilityNodeInfo> hongbao = rootInActiveWindow.findAccessibilityNodeInfosByText("拆红包");
    if (hongbao != null && !hongbao.isEmpty()) {
        PerformClickUtils.findTextAndClick(accessibilityService, "拆红包");
    } else {
        List<AccessibilityNodeInfo> accessibilityNodeInfosByViewId = rootInActiveWindow.findAccessibilityNodeInfosByViewId(hongbao_open);//开红包的ID
        if (accessibilityNodeInfosByViewId != null && !accessibilityNodeInfosByViewId.isEmpty()) {
            PerformClickUtils.findViewIdAndClick(this, hongbao_open);
        }
    }
}

获取红包的金额

private void getMoney() {
    //获取当前时间
    date = new Date(System.currentTimeMillis());
    String time = dateFormat.format(date);
    Money money = new Money();
    money.setTime(time);
    System.out.println("time--" + time);
    AccessibilityNodeInfo rootInActiveWindow = getRootInActiveWindow();
    if (rootInActiveWindow == null) {
        return;
    }
    //获取钱包来源
    List<AccessibilityNodeInfo> accessibilityNodeInfosResource = rootInActiveWindow.findAccessibilityNodeInfosByViewId(hongbao_resource);
    if (accessibilityNodeInfosResource != null && accessibilityNodeInfosResource.size() > 0) {
        if (accessibilityNodeInfosResource.get(0) != null) {
            resource = accessibilityNodeInfosResource.get(0).getText().toString();
            money.setResource(resource);
        }
    }
    //获取钱包金额
    List<AccessibilityNodeInfo> accessibilityNodeInfosNumber = rootInActiveWindow.findAccessibilityNodeInfosByViewId(hongbao_number);
    if (accessibilityNodeInfosNumber != null && !accessibilityNodeInfosNumber.isEmpty()) {
        if (accessibilityNodeInfosNumber.get(0) != null) {
            number = accessibilityNodeInfosNumber.get(0).getText().toString();
            money.setMoney(number);
        }
    }
    System.out.println("money----" + money.getMoney());
    String objValue = Preferences.setObject(money);
    moneys.add(objValue);
    //点击返回按钮
    List<AccessibilityNodeInfo> back = rootInActiveWindow.findAccessibilityNodeInfosByText("返回");
    if (back != null) {
        PerformClickUtils.findTextAndClick(this, "返回");
    } else {
        PerformClickUtils.performBack(this);
    }
    PerformClickUtils.findTextAndClick(this, "聊天信息");
}
