如何配置Android AccessibilityService

问题描述

我正在调查Android AccessibilityService ，并希望查看所有可能的事件类型，
手势和按键事件。

I am investigating Android AccessibilityService and wanted to see all possible types of events,gestures and Key Events.

我能够接收所有无效的onAccessibilityEvent（final AccessibilityEvent accessibilityEvent）{}

我的服务永远不会收到受保护的布尔onGesture（int poseId）{} 或
受保护的布尔onKeyEvent（KeyEvent event）{} 呼叫。

however my service nevers receives protected boolean onGesture(int gestureId) {} orprotected boolean onKeyEvent(KeyEvent event) {} calls.

在辅助功能设置中启用我的辅助功能后，我看到该服务已连接

When I enable my accessibility service in the accessibility settings I see the service connect OK

然后我看到服务从公共无效ononAccessibilityEvent（final AccessibilityEvent accessibilityEvent）{} 方法注销

and I can see the service logging out from the public void onAccessibilityEvent(final AccessibilityEvent accessibilityEvent) {} method

我没有配置什么？还是配置错误？

What have I not configured? or configured incorrectly?

我的清单文件是这样的

<service
    android:name=".MyAccessibilityService"
    android:label="My Accessibility"
    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/accessibilityservice" />
</service>

xml可访问性服务的内容为：-

The xml accessibilityservice contents are :-

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeAllMask"
    android:accessibilityFeedbackType="feedbackSpoken"
    android:accessibilityFlags="flagDefault"
    android:canRequestEnhancedWebAccessibility="true"
    android:canRequestFilterKeyEvents="true"
    android:canRequestTouchExplorationMode="true"
    android:canRetrieveWindowContent="true"
    android:notificationTimeout="1000"
    android:packageNames="com.research.my.accessibility" />

服务AccessibilityServiceInfo如下：-

The service AccessibilityServiceInfo is as follows:-

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

    final AccessibilityServiceInfo accessibilityServiceInfo = new AccessibilityServiceInfo();
    accessibilityServiceInfo.eventTypes = AccessibilityEvent.TYPES_ALL_MASK;
    accessibilityServiceInfo.feedbackType = AccessibilityServiceInfo.FEEDBACK_ALL_MASK;
    accessibilityServiceInfo.packageNames = new String[] {"com.research.my.accessibility"};
    accessibilityServiceInfo.notificationTimeout = 1000;
    setServiceInfo(accessibilityServiceInfo);
}

推荐答案

可能是您需要更改标记

<?xml version="1.0" encoding="utf-8"?>
<accessibility-service
xmlns:android="http://schemas.android.com/apk/res/android"
android:accessibilityEventTypes="typeContextClicked|typeViewClicked"
android:packageNames="com.example.andres.eventcapture"
android:accessibilityFlags="flagRequestFilterKeyEvents"
android:accessibilityFeedbackType="feedbackAllMask"
android:notificationTimeout="50"
android:canRetrieveWindowContent="true"
android:settingsActivity=""
android:canRequestFilterKeyEvents="true"
/>

类似这样的东西。

也可以尝试FLAG_REQUEST_TOUCH_EXPLORATION_MODE

or you can also try FLAG_REQUEST_TOUCH_EXPLORATION_MODE
