AccessibilityService 配置

1. xml

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
                       android:accessibilityEventTypes="typeAllMask"
                       android:accessibilityFeedbackType="feedbackAllMask"
                       android:accessibilityFlags="flagDefault|flagRetrieveInteractiveWindows|flagIncludeNotImportantViews"
                       android:canPerformGestures="true"
                       android:canRequestFilterKeyEvents="true"
                       android:canRetrieveWindowContent="true"
                       android:canRequestEnhancedWebAccessibility="true"
                       android:description="@string/accessibility_desc"
                       android:notificationTimeout="100"/>

2.manifest

  <service
                android:name=".service.MainService"
                android:enabled="true"
                android:exported="true"
                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_config"/>
        </service>

3.獲取控件信息

public class MainService extends AccessibilityService {

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {

        switch (event.getEventType()) {

            //窗口內容發生改變時觸發
            case AccessibilityEvent.TYPE_VIEW_CLICKED:
                //跳轉到新的頁面，或者彈出了window，dialog等
            case AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED:
                //滾動時觸發
            case AccessibilityEvent.TYPE_VIEW_SCROLLED:
                //某個view的內容發生的變化時觸發
            case AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED:

                break;
        }

        // 此方法是在主線程中回調過來的，所以消息是阻塞執行的
        // 獲取包名
        if (event.getPackageName() != null) {

            String pkgName = event.getPackageName().toString();

        }

        int eventType = event.getEventType();

        String eventText = "";
