android AccessibilityService的学习和应用

最近公司要用钉钉作为打卡工具，说好的弹性上班呢，于是乎想找个破解方法，百度了一圈，有个大神的文章可以解决此问题，文章地址：

原来和微信抢红包一样里面用到了一个非常关键的类 AccessibilityService，这个类的作用就是监听屏幕发生各种改变事件，比如手机打开红包页面，当一旦出现红包就自动去模拟点击红包，肯定比人为速度更快，那么钉钉打卡一样的原理，比如早上9点设置一个定时器或者给安卓了钉钉的手机打个电话神马的，然后去触发打开钉钉，然后检测到页面相应的变化去处理，一步一步的就可以到打卡页面打卡了，这里贴下根据大神的代码稍微改动了一点点，

代码很简单，稍微看一下就能明白其中原理。

这里主要用到了3个知识点，

一、根据包名打开APP

import java.util.List;import android.content.ComponentName;import android.content.Context;import android.content.Intent;import android.content.pm.PackageInfo;import android.content.pm.PackageManager;import android.content.pm.PackageManager.NameNotFoundException;import android.content.pm.ResolveInfo;public class Utils {    public static void openCLD(String packageName,Context context) {        PackageManager packageManager = context.getPackageManager();        PackageInfo pi = null;        try {            pi = packageManager.getPackageInfo("com.alibaba.android.rimet", 0);        } catch (NameNotFoundException e) {        }        Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);        resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);        resolveIntent.setPackage(pi.packageName);        List<ResolveInfo> apps = packageManager.queryIntentActivities(resolveIntent, 0);        ResolveInfo ri = apps.iterator().next();        if (ri != null ) {            String className = ri.activityInfo.name;            Intent intent = new Intent(Intent.ACTION_MAIN);            intent.addCategory(Intent.CATEGORY_LAUNCHER);            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            ComponentName cn = new ComponentName(packageName, className);            intent.setComponent(cn);            context.startActivity(intent);        }    }}

二、注册一个广播接受者，用于接受电话短信之类的广播

import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.telephony.TelephonyManager;import android.app.Service;import android.util.Log;public class PhoneReceiver extends BroadcastReceiver {    private static final String TAG = "message";    private static boolean mIncomingFlag = false;    private static String mIncomingNumber = null;    @Override    public void onReceive(Context context, Intent intent) {        // 如果是拨打电话        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {            mIncomingFlag = false;            String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);            Log.i(TAG, "call OUT:" + phoneNumber);        } else {            // 如果是来电            TelephonyManager tManager = (TelephonyManager) context                    .getSystemService(Service.TELEPHONY_SERVICE);            switch (tManager.getCallState()) {                case TelephonyManager.CALL_STATE_RINGING:                    mIncomingNumber = intent.getStringExtra("incoming_number");                    Log.i(TAG, "RINGING :" + mIncomingNumber);                    if(mIncomingNumber!=null&&mIncomingNumber.equals("15606708596")){                        Utils.openCLD("com.alibaba.android.rimet", context);                        DingService.instance.setServiceEnable();                    }                    break;                case TelephonyManager.CALL_STATE_OFFHOOK:                    if (mIncomingFlag) {                        Log.i(TAG, "incoming ACCEPT :" + mIncomingNumber);                    }                    break;                case TelephonyManager.CALL_STATE_IDLE:                    if (mIncomingFlag) {                        Log.i(TAG, "incoming IDLE");                    }                    break;            }        }    }}

三、重点，继承AccessibilityService，重写@Override
public void onAccessibilityEvent(AccessibilityEvent event);event包含了整个屏幕变化的监听事件，可以根据这些事件来处理自己想要的操作

import java.util.ArrayList;import java.util.List;import android.accessibilityservice.AccessibilityService;import android.util.Log;import android.view.accessibility.AccessibilityEvent;import android.view.accessibility.AccessibilityNodeInfo;import android.widget.Toast;public class DingService extends AccessibilityService {private String TAG = getClass().getSimpleName();private  boolean  isFinish = false;public static DingService instance;private int index = 1;/** * 获取到短信通知 * 0.唤醒屏幕 * 1.打开钉钉 * 2.确保当前页是主页界面 * 3.找到“工作”tab并且点击 * 4.确保到达签到页面 * 5.找到签到按钮，并且点击 * 6.判断签到是否成功 * 1.成功，退出程序 * 2.失败，返回到主页，重新从1开始签到 */@Overridepublic void onAccessibilityEvent(AccessibilityEvent event) {// TODO Auto-generated method stub// final int eventType = event.getEventType();ArrayList<String> texts = new ArrayList<String>();Log.i(TAG, "事件---->" + event.getEventType());if(isFinish){return;}AccessibilityNodeInfo nodeInfo = getRootInActiveWindow();if(nodeInfo == null) {Log.w(TAG, "rootWindow为空");return ;}// nodeInfo.// System.out.println("nodeInfo"+nodeInfo);System.out.println("index:"+index);switch (index) {case 1: //进入主页OpenHome(event.getEventType(),nodeInfo);break;case 2: //进入签到页OpenQianDao(event.getEventType(),nodeInfo);break;case 3:doQianDao(event.getEventType(),nodeInfo);break;default:break;}}private ArrayList<String> getTextList(AccessibilityNodeInfo node,ArrayList<String> textList){if(node == null) {Log.w(TAG, "rootWindow为空");return null;}if(textList==null){textList = new ArrayList<String>();}String text = node.getText().toString();if(text!=null&&text.equals("")){textList.add(text);}//      node.getreturn null;}private void OpenHome(int type,AccessibilityNodeInfo nodeInfo) {if(type == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED){//判断当前是否是钉钉主页List<AccessibilityNodeInfo> homeList = nodeInfo.findAccessibilityNodeInfosByText("成长");if(!homeList.isEmpty()){//点击boolean isHome = click( "成长");System.out.println("---->"+isHome);index = 2;System.out.println("点击进入主页签到");Log.d(TAG, "点击进入主页签到");}}}private void OpenQianDao(int type,AccessibilityNodeInfo nodeInfo) {if(type == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED){//判断当前是否是主页的签到页List<AccessibilityNodeInfo> qianList = nodeInfo.findAccessibilityNodeInfosByText("考勤打卡");if(!qianList.isEmpty()){boolean ret = click( "考勤打卡");index = 3;System.out.println("点击进入签到页面详情");Log.d(TAG, "点击进入点击进入签到页面详情");}// index = ret?3:1;}}private void doQianDao(int type,AccessibilityNodeInfo nodeInfo) {if(type == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED){//判断当前页是否是签到页List<AccessibilityNodeInfo> case1 = nodeInfo.findAccessibilityNodeInfosByText("上班时间");//if(!case1.isEmpty()){//click("开启我的签到之旅");//System.out.println("点击签到之旅");//}List<AccessibilityNodeInfo> case2 = nodeInfo.findAccessibilityNodeInfosByText("下班时间");//if(!case2.isEmpty()){//click("我知道了");//System.out.println("点击我知道对话框");//}List<AccessibilityNodeInfo> case3 = nodeInfo.findAccessibilityNodeInfosByText("更新打卡>");Log.d(TAG, "case1 " + case1 + "case2 " + case2 + "case3 " + case3);if(!case1.isEmpty() && !case2.isEmpty() && !case3.isEmpty()){Toast.makeText(getApplicationContext(), "发现目标啦！！~~", Toast.LENGTH_SHORT).show();System.out.println("发现目标啦！");Log.d(TAG, "发现目标啦！");click("更新打卡>");isFinish = true;}}//if(type == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED){//List<AccessibilityNodeInfo> case3 = nodeInfo.findAccessibilityNodeInfosByText("签到");//if(!case3.isEmpty()){//Toast.makeText(getApplicationContext(), "发现目标啦！！~~", 1).show();//}//}}//通过文字点击private boolean click(String viewText){AccessibilityNodeInfo nodeInfo = getRootInActiveWindow();if(nodeInfo == null) {Log.w(TAG, "点击失败，rootWindow为空");return false;}List<AccessibilityNodeInfo> list = nodeInfo.findAccessibilityNodeInfosByText(viewText);if(list.isEmpty()){//没有该文字的控件Log.w(TAG, "点击失败，"+viewText+"控件列表为空");return false;}else{//有该控件//找到可点击的父控件AccessibilityNodeInfo view = list.get(0);return onclick(view);  //遍历点击}}private boolean onclick(AccessibilityNodeInfo view){if(view.isClickable()){view.performAction(AccessibilityNodeInfo.ACTION_CLICK);Log.w(TAG, "点击成功");return true;}else{AccessibilityNodeInfo parent = view.getParent();if(parent==null){return false;}onclick(parent);}return false;}//点击返回按钮事件private void back(){performGlobalAction(AccessibilityService.GLOBAL_ACTION_BACK);}@Overridepublic void onInterrupt() {// TODO Auto-generated method stub}@Overrideprotected void onServiceConnected() {// TODO Auto-generated method stubsuper.onServiceConnected();Log.i(TAG, "service connected!");Toast.makeText(getApplicationContext(), "连接成功！", Toast.LENGTH_SHORT).show();instance = this;}public void setServiceEnable(){isFinish = false;Toast.makeText(getApplicationContext(), "服务可用开启！", Toast.LENGTH_SHORT).show();index = 1;}}

注意：运行安装好这个项目后，以华为手机为例，须要在手机设置——高级设置——辅助功能找个这个APP然后开启AccessibilityService这个服务，不然运行了程序会报空指针，说AccessibilityService为空。

好了，又可以愉快玩耍了
