Java 如何ı；可以使用AccessibilityService#Dispatch手势

我遵循这个思路：

因为我是一个新的开发人员，我不知道如何使用代码，代码显示一条红线

MyService完整代码：

public class MyService extends AccessibilityService {

    public MyService() {
    }


    @Override
    public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {

    }

    @Override
    public void onInterrupt() {

    }





    private static GestureDescription createClick(float x, float y) {
        // for a single tap a duration of 1 ms is enough
        final int DURATION = 1;

        Path clickPath = new Path();
        clickPath.moveTo(x, y);
        GestureDescription.StrokeDescription clickStroke =
                new GestureDescription.StrokeDescription(clickPath, 0, DURATION);
        GestureDescription.Builder clickBuilder = new GestureDescription.Builder();
        clickBuilder.addStroke(clickStroke);
        return clickBuilder.build();
    
    
    
    
    }


    callback = new AccessibilityService.GestureResultCallback() {
        @Override
        public void onCompleted(GestureDescription gestureDescription) {
            super.onCompleted(gestureDescription);
    
        }

        @Override
        public void onCancelled(GestureDescription gestureDescription) {
            super.onCancelled(gestureDescription);
     
        }
    };

    // accessibilityService: contains a reference to an accessibility service
// callback: can be null if you don't care about gesture termination
    boolean result = accessibilityService.dispatchGesture(createClick(x, y), callback, null);



}
