android AccessibilityService无障碍功能开发，实现自动化测试

Android AccessibilityService无障碍功能开发，实现自动化测试，这里使用抖音为例子，仅供技术研究学习使用。

使用方法

安装好APP后，需要打开无障碍功能，打开后，在次打开抖音APP，随便找一个直播间，上下滑动切换直接后，实现模拟点击屏幕，可以自动完成关注。

代码如下

package com.nyw.testclick;import androidx.annotation.Requiresapi;import androidx.appcompat.app.AppCompatActivity;import android.accessibilityservice.AccessibilityService;import android.accessibilityservice.AccessibilityServiceInfo;import android.accessibilityservice.GestureDescription;import android.content.Context;import android.content.Intent;import android.content.pm.PackageInfo;import android.content.pm.PackageManager;import android.content.pm.ServiceInfo;import android.graphics.Path;import android.graphics.Point;import android.graphics.Rect;import android.net.Uri;import android.os.Build;import android.os.Bundle;import android.provider.Settings;import android.text.TextUtils;import android.util.Log;import android.view.accessibility.AccessibilityManager;import android.view.accessibility.AccessibilitynodeInfo;import android.widget.Toast;import java.util.List;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        boolean enabled = isAccessibilityServiceEnabled(this, MyAccessibilityService.class);        //判断是否安装抖音        boolean exist1 = checkAppInstalled(MainActivity.this, "com.ss.android.uGC.aweme");        //抖音极速版        //boolean exist1 = checkAppInstalled(getContext(), "com.ss.android.article.video");        //抖音火山版        //boolean exist1 = checkAppInstalled(getContext(), "com.ss.android.ugc.live");        if (exist1) {            Intent intent = new Intent();            //抖音 打开个人中心  104248958804 需要去获取抖音的UserId//            intent.setData(Uri.parse("snssdk1128://user/profile/104248958804"));            // 打开首页            intent.setData(Uri.parse("snssdk1128://feed?refer=WEB&gd_label=1"));            //抖音极速版            //intent.setData(Uri.parse("snssdk1112://user/profile/104248958804"));            //抖音火山版            //intent.setData(Uri.parse("snssdk1112://profile?id=104248958804"));            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            startActivity(intent);        } else {            Toast.makeText(MainActivity.this, "请先安装此应用", Toast.LENGTH_SHORT).show();        }        if (enabled==false){            final String actionOpen=Settings.ACTION_ACCESSIBILITY_SETTINGS;//系统辅助功能服务            Intent intent=new Intent(actionOpen);            startActivity(intent);        }    }        public static boolean isAccessibilityServiceEnabled(Context context, Class service) {        AccessibilityManager am = (AccessibilityManager) context.getSystemService(Context.ACCESSIBILITY_SERVICE);        List enabledServices = am.getEnabledAccessibilityServiceList(AccessibilityServiceInfo.FEEDBACK_ALL_MASK);        for (AccessibilityServiceInfo enabledService : enabledServices) {            ServiceInfo enabledServiceInfo = enabledService.getResolveInfo().serviceInfo;            if (enabledServiceInfo.packageName.equals(context.getPackageName()) && enabledServiceInfo.name.equals(service.getName()))                return true;        }        return false;    }        private boolean checkAppInstalled(Context context, String pName) {        if (pName == null || pName.isEmpty()) {            return false;        }        final PackageManager packageManager = context.getPackageManager();        List info = packageManager.getInstalledPackages(0);        if (info == null || info.isEmpty()) {            return false;        }        for (int i = 0; i < info.size(); i++) {            if (pName.equals(info.get(i).packageName)) {                return true;            }        }        return false;    }}

 自定义一个服务MyAccessibilityService，继承AccessibilityService,实现2个方法，重写一个方法，代码如下

                   break;                case AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED:                    // 界面文字改动                    Log.i("sdfkslfsfks", "界面文字改动");                    perforGlobalClick("com.ss.android.ugc.aweme:id/gsb");

AndroidManifest.xml文件配制如下

 在xml中添加一个accessible_service_config文件，代码如下
