最近在研究Android辅助服务，实现了这个小工具，也算是对最近学习的一个总结。
通过Android 无障碍辅助功能实现模拟点击控件来实现
检查被删好友有两种方法：
本文采用建群的方式进行检查。
本人微信有300好友，全部检测一遍只需3分钟即可，亲测已经成功，
但是建群没有超过40人 会有个别好友会受到打扰消息，可能是微信哪里的bug，具体原因未知。
此软件通过无障碍辅助进行模拟点击，无任何外挂木马，无封号风险

public class InspectWechatFriendService extends AccessibilityService{
@Override
protected void onServiceConnected() {//辅助服务被打开后 执行此方法
super.onServiceConnected();
}
@Override
public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {//监听手机当前窗口状态改变 比如 Activity 跳转,内容变化,按钮点击等事件
}
@Override
public void onInterrupt() {//辅助服务被关闭 执行此方法
}
}
通过getRootInActiveWindow方法获取当前窗口信息，通过findAccessibilityNodeInfosByText方法找到当前对应控件进行模拟点击
public class PerformClickUtils {
/**
* 在当前页面查找文字内容并点击
*
* @param text
*/
public static void findTextAndClick(AccessibilityService accessibilityService,String text) {
AccessibilityNodeInfo accessibilityNodeInfo = accessibilityService.getRootInActiveWindow();
if (accessibilityNodeInfo == null) {
return;
}
List nodeInfoList = accessibilityNodeInfo.findAccessibilityNodeInfosByText(text);
if (nodeInfoList != null && !nodeInfoList.isEmpty()) {
for (AccessibilityNodeInfo nodeInfo : nodeInfoList) {
if (nodeInfo != null && (text.equals(nodeInfo.getText()) || text.equals(nodeInfo.getContentDescription()))) {
performClick(nodeInfo);
break;
}
}
}
}
/**
* 检查viewId进行点击
*
* @param accessibilityService
* @param id
*/
public static void findViewIdAndClick(AccessibilityService accessibilityService,String id) {
AccessibilityNodeInfo accessibilityNodeInfo = accessibilityService.getRootInActiveWindow();
if (accessibilityNodeInfo == null) {
return;
}
List nodeInfoList = accessibilityNodeInfo.findAccessibilityNodeInfosByViewId(id);
if (nodeInfoList != null && !nodeInfoList.isEmpty()) {
for (AccessibilityNodeInfo nodeInfo : nodeInfoList) {
if (nodeInfo != null) {
performClick(nodeInfo);
break;
}
}
}
}
/**
* 在当前页面查找对话框文字内容并点击
*
* @param text1 默认点击text1
* @param text2
*/
public static void findDialogAndClick(AccessibilityService accessibilityService,String text1, String text2) {
AccessibilityNodeInfo accessibilityNodeInfo = accessibilityService.getRootInActiveWindow();
if (accessibilityNodeInfo == null) {
return;
}
List dialogWait = accessibilityNodeInfo.findAccessibilityNodeInfosByText(text1);
List dialogCOnfirm= accessibilityNodeInfo.findAccessibilityNodeInfosByText(text2);
if (!dialogWait.isEmpty() && !dialogConfirm.isEmpty()) {
for (AccessibilityNodeInfo nodeInfo : dialogWait) {
if (nodeInfo != null && text1.equals(nodeInfo.getText())) {
performClick(nodeInfo);
break;
}
}
}
}
//模拟点击事件
public static void performClick(AccessibilityNodeInfo nodeInfo) {
if (nodeInfo == null) {
return;
}
if (nodeInfo.isClickable()) {
nodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);
} else {
performClick(nodeInfo.getParent());
}
}
//模拟返回事件
public static void performBack(AccessibilityService service) {

获取当前窗口的classname 通过classname进行判断当前手机处于某个界面
下面代码逻辑：
下面为对应逻辑代码：
@Override
public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {//监听手机当前窗口状态改变 比如 Activity 跳转,内容变化,按钮点击等事件
//如果手机当前界面的窗口发送变化
if (accessibilityEvent.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
//获取当前activity的类名:
String currentWindowActivity = accessibilityEvent.getClassName().toString();
if(!hasComplete){
if ("com.tencent.mm.ui.contact.SelectContactUI".equals(currentWindowActivity)) {
canChecked = true;
createGroup();

uiautomatorviewer可以检查当前手机的布局结构，如果想更精确的找到控件位置，uiautomatorviewer必不可少！
使用方法：
$uiautomatorviewer
