AccessibilityService 类似微信自动抢红包的实现

类似微信抢红包也就是自动点击按钮实现

1 创建一个类继承AccessibilityService

public class AutoClickService extends AccessibilityService {
    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    protected void onServiceConnected() {
         
        super.onServiceConnected();
    }

    private boolean onceClick = false;

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)
    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
      

    }

    @Override
    public void onInterrupt() {
        
        
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        
    }

2 在Mainfest文件中配置service

<service
            android:name=".AutoClickService"
            android:label="点击测试"
            android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
            <intent-filter>
                <action android:name="android.accessibilityservice.AccessibilityService" />
            </intent-filter>
            <meta-data
                android:name="android.accessibilityservice"
                android:resource="@xml/auto_click_service_config" />
        </service>

其中android:resource="@xml/auto_click_service_config"配置文件在AndroidStudio中res文件加下xml文件夹中创建auto_click_service_config.xml

如果res文件夹下面没有xml文件夹，可以新建res ——>Android Resources File ——> Resource type 选择xml创建即可。

auto_click_service_config.xml如下

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeAllMask"
    android:accessibilityFeedbackType="feedbackSpoken"
    android:canRetrieveWindowContent="true"
    android:accessibilityFlags="flagDefault|flagRetrieveInteractiveWindows|flagIncludeNotImportantViews|flagReportViewIds"
    android:description="@string/auto_click_service_description"
    android:packageNames="com.sz.lyw.demoactivity"
    android:notificationTimeout="100" />

其中android:packageNames换成你想要监听的APP包名。

注意：很多时候无障碍权限是默认关闭的，需要先判断一下是否已打开该权限

public static boolean isAccessibilitySettingsOn(Context mContext, Class<? extends AccessibilityService> clazz) {
        int accessibilityEnabled = 0;
        final String service = mContext.getPackageName() + "/" + clazz.getCanonicalName();
        try {
            accessibilityEnabled = Settings.Secure.getInt(mContext.getApplicationContext().getContentResolver(),
                    Settings.Secure.ACCESSIBILITY_ENABLED);
        } catch (Settings.SettingNotFoundException e) {
            e.printStackTrace();
        }
        TextUtils.SimpleStringSplitter mStringColonSplitter = new TextUtils.SimpleStringSplitter(':');
        if (accessibilityEnabled == 1) {
            String settingValue = Settings.Secure.getString(mContext.getApplicationContext().getContentResolver(),
                    Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES);
            if (settingValue != null) {
                mStringColonSplitter.setString(settingValue);
                while (mStringColonSplitter.hasNext()) {
                    String accessibilityService = mStringColonSplitter.next();
                    if (accessibilityService.equalsIgnoreCase(service)) {
                        return true;
                    }
                }
            }
        }
        return false;
    }

如果没有打开可以通过 startActivity(new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS)); 打开

在上面清单文件配置service时 android:label="点击测试" ，点击红色框，然后允许即可

3 如何点击指定按钮

前两步已经将service创建配置好，接下来就是如何点击指定按钮，处理是在我们自定义的AutoClickService类中

public class AutoClickService extends AccessibilityService {
    @Override
    public void onCreate() {
        super.onCreate();
        Utils.logPrint(" onCreate ");

    }

    @Override
    protected void onServiceConnected() {
       
        super.onServiceConnected();
    }

    private boolean onceClick = false;

    @TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR2)
    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
         
         AccessibilityOperate.getOperate().updateEvent(this, event);

         
         List<AccessibilityNodeInfo> accessibilityNodeInfos =
                 AccessibilityOperate.getOperate().findNodesByText("怎么着");


         AccessibilityOperate.getOperate().setAimVeiwList(accessibilityNodeInfos);

        
    }

    @Override
    public void onInterrupt() {
       
        Utils.logPrint(" onInterrupt ");
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
       
    }

}

其中AccessibilityOperate 是一个封装类 

public class AccessibilityOperate {

    public static AccessibilityOperate operate;

    public static AccessibilityOperate getOperate() {
        if (null == operate) {
            synchronized (AccessibilityOperate.class) {
                if (null == operate) {
                    operate = new AccessibilityOperate();
                }
            }
        }


        return operate;
    }


    private AccessibilityService mAccessibilityService;
    private AccessibilityEvent mAccessibilityEvent;

    public void updateEvent(AccessibilityService service, AccessibilityEvent event) {
        if (service != null && mAccessibilityService == null) {
            mAccessibilityService = service;
        }
        if (event != null) {
            mAccessibilityEvent = event;
        }
    }

    public List<AccessibilityNodeInfo> findNodesByText(String text) {
        Utils.logPrint("______________________START_________________________");
        AccessibilityNodeInfo nodeInfo = getRootNodeInfo();
        if (nodeInfo != null) {
            Utils.logPrint("toString：" + nodeInfo.toString());
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
                //需要在xml文件中声明权限android:accessibilityFlags="flagReportViewIds"
                // 并且版本大于4.3 才能获取到view 的 ID
                Utils.logPrint("getClassName：" + nodeInfo.getViewIdResourceName());
            }
            Utils.logPrint("______________________END_________________________");
            return nodeInfo.findAccessibilityNodeInfosByText(text);
        } else {
            Utils.logPrint("findNodesByText nodeInfo is null ");
        }
        return null;
    }

    public List<AccessibilityNodeInfo> findNodesById(String viewId) {
        AccessibilityNodeInfo nodeInfo = getRootNodeInfo();
        if (nodeInfo != null) {
            if (Build.VERSION.SDK_INT >= 18) {
                return nodeInfo.findAccessibilityNodeInfosByViewId(viewId);
            }
        }
        return null;
    }

    private AccessibilityNodeInfo getRootNodeInfo() {
        AccessibilityEvent curEvent = mAccessibilityEvent;
        AccessibilityNodeInfo nodeInfo = null;
        if (Build.VERSION.SDK_INT >= 16) {
            if (mAccessibilityService != null) {
                nodeInfo = mAccessibilityService.getRootInActiveWindow();
            }
        } else {
            nodeInfo = curEvent.getSource();
        }
        return nodeInfo;
    }


    private List<AccessibilityNodeInfo> nodeInfos;

    public void setAimVeiwList(List<AccessibilityNodeInfo> nodeInfos) {
        this.nodeInfos = nodeInfos;
    }


    public boolean performClick() {

        if (nodeInfos != null && !nodeInfos.isEmpty()) {
            Utils.logPrint(" size " + nodeInfos.size());
            AccessibilityNodeInfo node;
            for (int i = 0; i < nodeInfos.size(); i++) {
                node = nodeInfos.get(i);
                // 获得点击View的类型
                Utils.logPrint("node.toString()：" + node.toString());
                // 进行模拟点击
                if (node.isEnabled()) {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                        return node.performAction(AccessibilityNodeInfo.ACTION_CLICK);
                    }
                }
            }
        } else {
            Utils.logPrint(" nodeInfos is null or empty ");
        }
        return false;
    }

}

AccessibilityOperate.getOperate().findNodesByText("怎么着"); 是我监听的APP界面有一个Button,按钮的text是 怎么着；

其中 performClick（）方法是在满足指定条件下调用；

我创建了一个AndroidAutoClickDemo的项目监听上图项目DemoActivity

然后在AndroidAutoClickDemo开启一个定时每6秒调用一次AccessibilityOperate.getOperate().performClick();

DemoActivity项目中就会在按钮被点击时弹出一个Toast;

具体点击策略视情况决定；
