Android AccessibilityService 自动化操作抖音

用到的技术和工具AccessibilityService和uiautomatorviewer.

设备要求:android7.0以上因为AccessibilityService在7.0以后才支持手势操作

抖音版本5.8.0(因为版本不同view的id也不同)

AccessibilityService:实现自动化操作的系统服务. 参考博客:(AccessibilityService) Android 辅助功能笔记

uiautomatorviewer:找到页面ID的插件,在android的SDK里面:Android\Sdk\tools\bin\uiautomatorviewer.bat

获取权限:在res-->xml下新建xml文件
android:canPerformGestures="true" 允许进行手势操作
android:canRetrieveWindowContent="true" 允许读取页面上的数据

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeAllMask"
    android:accessibilityFeedbackType="feedbackGeneric"
    android:accessibilityFlags="flagDefault"
    android:canPerformGestures="true"
    android:canRetrieveWindowContent="true"
    android:notificationTimeout="100" />

按钮点击事件(View必须是可点击的clickable=true,在uiautomatorviewer中可查看View的属性)

 /**
   * 根据ID点击某个视图
   */
    public void perforGlobalClick(String id) {
        AccessibilityNodeInfo nodeInfo = getRootInActiveWindow();
        if (nodeInfo != null) {
            List<AccessibilityNodeInfo> list = nodeInfo.findAccessibilityNodeInfosByViewId(id);
            nodeInfo.recycle();
            for (AccessibilityNodeInfo item : list) {
                item.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            }
        }
    }

获取TextView的文本

 /**
     * 获取指定ID的文本
     */
    private String getTextById(String id) {
        AccessibilityNodeInfo nodeInfo = getRootInActiveWindow();
        if (nodeInfo != null) {
            List<AccessibilityNodeInfo> list = nodeInfo.findAccessibilityNodeInfosByViewId(id);
            nodeInfo.recycle();
            for (AccessibilityNodeInfo item : list) {
                return item.getText() + "";
            }
        }
        return "";
    }

判断View是否存在

 /**
     * 判断页面是否有此文本的view
     */
    private boolean viewByText(String str) {
        AccessibilityNodeInfo nodeInfo = getRootInActiveWindow();
        if (nodeInfo != null) {
            List<AccessibilityNodeInfo> list = nodeInfo.findAccessibilityNodeInfosByText(str);
            nodeInfo.recycle();
            for (AccessibilityNodeInfo item : list) {
                if (str.equals(item.getText().toString())) {
                    return true;
                }
            }
        }
        return false;
    }

模拟滑动屏幕

 //上划主页面
    private void MainActivityToUp() {
        final int x = ScreenUtils.getWindowsWidth(this) / 2;
        final int y = ScreenUtils.getWindowsHeight(this) / 2;
        Path path = new Path();
        path.moveTo(x, y);
        path.lineTo(x, 0);
        GestureDescription.Builder builder = new GestureDescription.Builder();
        builder.addStroke(new GestureDescription.StrokeDescription(path, 100L, 50L));
        GestureDescription gesture = builder.build();
        dispatchGesture(gesture, new GestureResultCallback() {
            @Override
            public void onCompleted(GestureDescription gestureDescription) {
                super.onCompleted(gestureDescription);
                Log.e(TAG, "onCompleted: 主页上滑.");
            }

            @Override
            public void onCancelled(GestureDescription gestureDescription) {
                super.onCancelled(gestureDescription);
            }
        }, null);
    }

具体实现

1.获取我们需要操作的View的ID

dianzan.png

点赞按钮 id:com.ss.android.ugc.aweme:id/c99
用户名 id:com.ss.android.ugc.aweme:id/title
文本信息 id:com.ss.android.ugc.aweme:id/ag7

2.新建一个DouyinService服务类继承AccessibilityService,重写onAccessibilityEvent(AccessibilityEvent event),和onInterrupt(), 我们主要操作onAccessibilityEvent(AccessibilityEvent event).他返回了我们需要的事件信息.

3.在清单文件中注册服务,xml/accessibility是配置信息

<service
            android:name=".service.DouyinService"
            android:enabled="true"
            android:exported="true"
            android:label="抖音小助手2.0"
            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/accessibility" />
        </service>

之后就是在onAccessibilityEvent(AccessibilityEvent event)的逻辑处理

   //显示更新提示框
        if (event.getClassName().toString().equals("com.ss.android.ugc.aweme.update.j")) {
            perforGlobalClick("com.ss.android.ugc.aweme:id/cev");//点击"以后再说"
        }
   //跳过广告
        if (event.getClassName().toString().equals("com.ss.android.ugc.aweme.splash.SplashActivity")) {
            perforGlobalClick("com.ss.android.ugc.aweme:id/ce2");//点击"跳过广告"
        }
   //点赞
       if ("android.widget.ImageView".equals(event.getClassName().toString())) {
                 perforGlobalClick("com.ss.android.ugc.aweme:id/c99");
                 Log.i(TAG, "用户名:" + getTextById(" id:com.ss.android.ugc.aweme:id/title"));
                 Log.i(TAG, "文本信息:" + getTextById(" id:com.ss.android.ugc.aweme:id/ag7"));
            }

运行项目

最后在手机设置-->服务功能(或无障碍)-->抖音助手2.0 选择打开,然后开启抖音就可以了
