QQ搶紅包插件實現

作為一個有女朋友的人，之前跟那些20年的單身狗搶紅包是屢戰屢敗。再加上最近群里面發紅包發的厲害，又想到快要過年了，到時候還不知道群里要發好多紅包，所以我將之前在網上宕的一份微信搶紅包的代碼修改了一下，實現了QQ搶紅包！可以支持搶QQ拼手氣紅包，普通紅包，口令紅包，現在再也不怕20年單身手速的人跟我搶紅包了！
先看測試效果圖：

搶QQ口令紅包：

可以看見，只要紅包一發出，自動填寫口令并發出，幫你將紅包搶到手！
搶QQ拼手氣紅包：

拼手氣紅包也是一樣，只要紅包一發出，自動幫你把紅包搶到手，是不是很爽的感覺？
搶QQ好友發送的紅包：

只要好友或者群里的人把紅包一發出，就會第一時間讓你搶到紅包！
所以只要在群里面開啟插件，搶紅包從來都是百發百中！

好了廢話不多說了，也不吹噓有多牛多好了，下面直接給大家上代碼：

MainActivity:

/*MainActivity中的代碼基本沒改變：*/
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();
    }

    /*開啟插件的按鈕*/
    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("關閉插件");  
             getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
         } else {    
             switchPlugin.setText("開啟插件");    
             getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);}
     }
}

這里是MainActivity中的全部代碼，是不是很少的樣子，主要是實現了一個按鈕去開啟ACCESSIBILITY_SERVICE。這個插件主要就是借助AccessibilityService這個服務來實現。所以剩下的代碼就都在這個服務中了！

QQHongbaoService：

public class QQHongbaoService extends AccessibilityService {
  private static final String WECHAT_OPEN_EN = "Open";

        info.getParent().performAction(AccessibilityNodeInfo.ACTION_CLICK);            
       }

      if (info.getClassName().toString().equals("android.widget.Button") && info.getText().toString().equals("發送")) {                
        info.performAction(AccessibilityNodeInfo.ACTION_CLICK);            
       }        
    } else {            
        for (int i = 0; i < info.getChildCount(); i++) {             
           if (info.getChild(i) != null) {                      
              recycle(info.getChild(i));              
            }

    }

    this.rootNodeInfo = event.getSource();        
    if (rootNodeInfo == null) {            
      return;       
     }        
    mReceiveNode = null;       
    checkNodeInfo();        
    /* 如果已經接收到紅包并且還沒有戳開 */       
    if (mLuckyMoneyReceived && (mReceiveNode != null)) {           
       int size = mReceiveNode.size();           
       if (size > 0) {               
           String id = getHongbaoText(mReceiveNode.get(size - 1));

           if (this.shouldReturn(id, now - lastFetchedTime))

           lastFetchedTime = now;                
           AccessibilityNodeInfo cellNode = mReceiveNode.get(size - 1);

           if (rowNode == null) {                      
              Log.e(TAG, "noteInfo is　null");                      
              return;                    
            } else {                     
                 recycle(rowNode);                  
            }                
         }
         mLuckyMoneyReceived = false;            
          }       
       }  
    }

  private void checkNodeInfo() {    
    if (rootNodeInfo == null) {      
        return;    
    }     
    /* 聊天會話窗口，遍歷節點匹配“點擊拆開”，“口令紅包”，“點擊輸入口令” */   
    List<AccessibilityNodeInfo> nodes1 = this.findAccessibilityNodeInfosByTexts(this.rootNodeInfo, new String[]{QQ_DEFAULT_CLICK_OPEN, QQ_HONG_BAO_PASSWORD, QQ_CLICK_TO_PASTE_PASSWORD, "發送"});    
    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) {  
      /* 獲取紅包上的文本 */    
      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為空    
      if (id == null) return true;    
      // 名稱和緩存不一致  
      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的全部代碼也在這里，代碼不多。首先，在這個服務中主要是通過findAccessibilityNodeInfosByText這個方法去獲我們需要的節點；然后，用performAction(AccessibilityNodeInfo.ACTION_CLICK)這個方法去點擊紅包節點，關鍵思路大概就是這樣！
另外如果是口令紅包，我們需要先按照上面的步驟將紅包戳開，然后通過performAction(AccessibilityNodeInfo.ACTION_CLICK)去點擊輸入口令，最后再通過點擊去發送即可實現！

QQHongbaoService需要在AndroidManifest.xml文件中注冊，
注冊的<application>節點如下圖：
