在 Android 手机主屏幕上检测触摸或滑动

Question

我想检测手机主屏幕上的触摸或滑动。检测后我需要执行我的操作。我为此使用辅助功能服务。但无法检测到手机主屏幕上的触摸或滑动。谁能帮帮我吗。下面是我的代码

global_accessibility_service.xml

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:accessibilityEventTypes="typeAllMask"
   android:accessibilityFeedbackType="feedbackAllMask"
   android:accessibilityFlags="flagDefault"
   android:canPerformGestures="true"
   android:canRequestTouchExplorationMode="true"
   android:canRetrieveWindowContent="true"
   android:description="@string/accessibility_service_description"
   android:notificationTimeout="100"
   tools:ignore="UnusedAttribute" />

不，这是不可能的。即使通过无障碍服务，我们也无法检测到主屏幕上的触摸或滑动。
