要實現Android懸浮窗的無障礙點擊功能,需要使用AccessibilityService服務和AccessibilityNodeInfo類。以下是一種實現方法:
public class MyAccessibilityService extends AccessibilityService {
@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
// 在這里處理Accessibility事件
}
@Override
public void onInterrupt() {
// 在這里處理服務中斷事件
}
// 模擬點擊事件的方法
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服務需要用戶手動開啟輔助功能,并在設置中給予相關權限。
