又想到快要过年了，到时候还不知道群里要发好多红包，所以我将之前在网上宕的一份微信抢红包的代码修改了一下，实现了QQ抢红包！可以支持抢QQ拼手气红包，普通红包，口令红包，现在再也不怕20年单身手速的人跟我抢红包了！

先看测试效果图：

1.抢QQ口令红包

可以看见，只要红包一发出，自动填写口令并发出，帮你将红包抢到手！

2.抢QQ拼手气红包

拼手气红包也是一样，只要红包一发出，自动帮你把红包抢到手，是不是很爽的感觉？

3.抢QQ好友发送的红包

只要好友或者群里的人把红包一发出，就会第一时间让你抢到红包！所以只要在群里面开启插件，抢红包从来都是百发百中！好了废话不多说了，也不吹嘘有多牛多好了，下面直接给大家上代码：

MainActivity:

/*MainActivity中的代码基本没改变：*/ public class MainActivity extends AppCompatActivity { private final Intent mAccessibleIntent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS); private Button switchPlugin; @Overrideprotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); switchPlugin = (Button) findViewById(R.id.button_accessible); updateServiceStatus(); } /*开启插件的按钮*/ public void onButtonClicked(View view) {startActivity(mAccessibleIntent);} @Overrideprotected void onResume() { super.onResume(); updateServiceStatus(); } } private void updateServiceStatus() { boolean serviceEnabled = false; AccessibilityManager accessibilityManager = (AccessibilityManager) getSystemService(Context.ACCESSIBILITY_SERVICE); List<AccessibilityServiceInfo> accessibilityServices = accessibilityManager.getEnabledAccessibilityServiceList(AccessibilityServiceInfo.FEEDBACK_GENERIC); for (AccessibilityServiceInfo info : accessibilityServices) { if (info.getId().equals(getPackageName() + "/.QQHongbaoService")) { serviceEnabled = true; break; } } if (serviceEnabled) { switchPlugin.setText("关闭插件"); getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); } else { switchPlugin.setText("开启插件"); getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);} } }

这里是MainActivity中的全部代码，是不是很少的样子，主要是实现了一个按钮去开启ACCESSIBILITY_SERVICE。这个插件主要就是借助AccessibilityService这个服务来实现。所以剩下的代码就都在这个服务中了！

QQHongbaoService：

public class QQHongbaoService extends AccessibilityService { private static final String WECHAT_OPEN_EN = "Open"; private static final String WECHAT_OPENED_EN = "You've opened"; private final static String QQ_DEFAULT_CLICK_OPEN = "点击拆开"; private final static String QQ_HONG_BAO_PASSWORD = "口令红包"; private final static String QQ_CLICK_TO_PASTE_PASSWORD = "点击输入口令"; private boolean mLuckyMoneyReceived; private String lastFetchedHongbaoId = null; private long lastFetchedTime = 0; private static final int MAX_CACHE_TOLERANCE = 5000; private AccessibilityNodeInfo rootNodeInfo; private List<AccessibilityNodeInfo> mReceiveNode; @TargetApi(Build.VERSION_CODES.KITKAT) public void recycle(AccessibilityNodeInfo info) { if (info.getChildCount() == 0) { /*这个if代码的作用是：匹配“点击输入口令的节点，并点击这个节点”*/ if(info.getText()!=null&&info.getText().toString().equals(QQ_CLICK_TO_PASTE_PASSWORD)) { info.getParent().performAction(AccessibilityNodeInfo.ACTION_CLICK); } /*这个if代码的作用是：匹配文本编辑框后面的发送按钮，并点击发送口令*/ if (info.getClassName().toString().equals("android.widget.Button") && info.getText().toString().equals("发送")) { info.performAction(AccessibilityNodeInfo.ACTION_CLICK); } } else { for (int i = 0; i < info.getChildCount(); i++) { if (info.getChild(i) != null) { recycle(info.getChild(i)); } } } } @TargetApi(Build.VERSION_CODES.JELLY_BEAN) @Override public void onAccessibilityEvent(AccessibilityEvent event) { this.rootNodeInfo = event.getSource(); if (rootNodeInfo == null) { return; } mReceiveNode = null; checkNodeInfo(); /* 如果已经接收到红包并且还没有戳开 */ if (mLuckyMoneyReceived && (mReceiveNode != null)) { int size = mReceiveNode.size(); if (size > 0) { String id = getHongbaoText(mReceiveNode.get(size - 1)); long now = System.currentTimeMillis(); if (this.shouldReturn(id, now - lastFetchedTime)) return; lastFetchedHongbaoId = id; lastFetchedTime = now; AccessibilityNodeInfo cellNode = mReceiveNode.get(size - 1); if (cellNode.getText().toString().equals("口令红包已拆开")) { return; } cellNode.getParent().performAction(AccessibilityNodeInfo.ACTION_CLICK); if (cellNode.getText().toString().equals(QQ_HONG_BAO_PASSWORD)) { AccessibilityNodeInfo rowNode = getRootInActiveWindow(); if (rowNode == null) { Log.e(TAG, "noteInfo isnull"); return; } else { recycle(rowNode); } } mLuckyMoneyReceived = false; } } } private void checkNodeInfo() { if (rootNodeInfo == null) { return; } /* 聊天会话窗口，遍历节点匹配“点击拆开”，“口令红包”，“点击输入口令” */ List<AccessibilityNodeInfo> nodes1 = this.findAccessibilityNodeInfosByTexts(this.rootNodeInfo, new String[]{QQ_DEFAULT_CLICK_OPEN, QQ_HONG_BAO_PASSWORD, QQ_CLICK_TO_PASTE_PASSWORD, "发送"}); if (!nodes1.isEmpty()) { String nodeId = Integer.toHexString(System.identityHashCode(this.rootNodeInfo)); if (!nodeId.equals(lastFetchedHongbaoId)) { mLuckyMoneyReceived = true; mReceiveNode = nodes1; } return; } } private String getHongbaoText(AccessibilityNodeInfo node) { /* 获取红包上的文本 */ String content; try { AccessibilityNodeInfo i = node.getParent().getChild(0); content = i.getText().toString(); } catch (NullPointerException npe) { return null; } return content; } private boolean shouldReturn(String id, long duration) { // ID为空 if (id == null) return true; // 名称和缓存不一致 if (duration < MAX_CACHE_TOLERANCE && id.equals(lastFetchedHongbaoId)) { return true; } return false; } private List<AccessibilityNodeInfo> findAccessibilityNodeInfosByTexts(AccessibilityNodeInfo nodeInfo, String[] texts) { for (String text : texts) { if (text == null) continue; List<AccessibilityNodeInfo> nodes = nodeInfo.findAccessibilityNodeInfosByText(text); if (!nodes.isEmpty()) { if (text.equals(WECHAT_OPEN_EN) && !nodeInfo.findAccessibilityNodeInfosByText(WECHAT_OPENED_EN).isEmpty()) { continue; } return nodes; } } return new ArrayList<>(); } @Override public void onInterrupt() {} }

QQHongbaoService的全部代码也在这里，代码不多。首先，在这个服务中主要是通过findAccessibilityNodeInfosByText这个方法去获我们需要的节点；然后用performAction(AccessibilityNodeInfo.ACTION_CLICK)这个方法去点击红包节点，关键思路大概就是这样！另外如果是口令红包，我们需要先按照上面的步骤将红包戳开，然后通过performAction(AccessibilityNodeInfo.ACTION_CLICK)去点击输入口令，最后再通过点击去发送即可实现！QQHongbaoService需要在AndroidManifest.xml文件中注册，

注册的<application>节点如下图：

总体来看，只是将微信抢红包的代码做了少量的修改，在这里要感谢各位大神对微信抢红包源码的贡献！最后也希望这篇文章能给大家有所帮助，在抢红包大战中虐死单身狗，再也不怕你20年的单身手速了！！！
