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 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 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 is　null");

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 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 findAccessibilityNodeInfosByTexts(AccessibilityNodeInfo nodeInfo, String[] texts) {

for (String text : texts) {

if (text == null) continue;

List 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！！！
