要实现Android悬浮窗的无障碍点击功能,需要使用AccessibilityService服务和AccessibilityNodeInfo类。以下是一种实现方法:
public class MyAccessibilityService extends AccessibilityService {
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
// 在这里处理Accessibility事件
}
@Override
public void onInterrupt() {
// 在这里处理服务中断事件
}
// 模拟点击事件的方法
public void performClick(AccessibilityNodeInfo nodeInfo) {
if (nodeInfo != null && nodeInfo.isClickable()) {
nodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);
}
}
}
<service android:name=".MyAccessibilityService"
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>
<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
android:accessibilityEventTypes="typeAllMask"
android:accessibilityFeedbackType="feedbackGeneric"
android:notificationTimeout="100"
android:packageNames="com.example.myapp"
android:settingsActivity="com.example.myapp.SettingsActivity" />
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
AccessibilityNodeInfo nodeInfo = event.getSource();
if (nodeInfo != null) {
if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED) {
performClick(nodeInfo);
}
}
}
需要注意的是,要使用AccessibilityService服务需要用户手动开启辅助功能,并在设置中给予相关权限。
