Android实现QQ抢红包插件

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 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<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！！！
