如何配置Android AccessibilityService

Question

我正在调查安卓AccessibilityService，并希望看到所有可能的事件类型，手势和关键事件。

我能接收到所有的public void onAccessibilityEvent(final AccessibilityEvent accessibilityEvent) {}

但是，我的服务nevers接收protected boolean onGesture(int gestureId) {}或protected boolean onKeyEvent(KeyEvent event) {}调用。

当我在辅助功能设置中启用辅助功能服务时，我会看到服务连接确定。

我可以看到服务从public void onAccessibilityEvent(final AccessibilityEvent accessibilityEvent) {}方法中退出。

我没有配置什么？还是配置不正确？

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可访问性服务内容如下：

<?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：

@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);
}

Answer 1

可能你需要更换旗子

<?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"
/>

就像这样。

或者您也可以尝试FLAG_REQUEST_TOUCH_EXPLORATION_MODE
