android – onAccessibilityEvent根本没有被调用

我正在尝试实现AccessibilityService.我在下面分享了我的代码.
当我从设置菜单打开辅助功能服务时,会调用onServiceConnected(),但根本不会调用onAccessibiltyEvent().请指导我这个.

清单文件中的服务声明.

<service
            android:name=".MyAccessibilityService"
            android:enabled="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_service_config" />
</service>

XML文件

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:description="@string/accessibility_service_description"
    android:accessibilityEventTypes="typeAllMask"
    android:canRequestFilterKeyEvents="true"
    android:accessibilityFlags="flagDefault"

    android:notificationTimeout="100"
    android:canRetrieveWindowContent="true"
    />

MyAccessibiltyService.java

public class MyAccessibilityService extends AccessibilityService {


    @Override
    protected void onServiceConnected() {
        super.onServiceConnected();
        Log.d(TAG,"Service Connected");

    }

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        System.out.println("Event Occurred");
        Log.d(TAG, "onAccessibilityEvent: event=" + event);
        AccessibilityNodeInfo nodeInfo = event.getSource();
        if (null == nodeInfo) return;


    }

    @Override
    public void onInterrupt() {
        Log.d(TAG,"Accessibility Interrupted" );

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Log.d(TAG,"Service Destroyed");
    }
}

请注意,我已经检查了所有stackoverflow答案,因此不要将其标记为重复.

解决方法:

我需要在accessibility_service_config文件中添加反馈类型以使其工作.

尝试添加此功能

android:accessibilityFeedbackType="feedbackAllMask"

使用Android 7.1.2在Nexus 6P上进行测试
