如何在HarmonyOS中获取触摸事件的触摸坐标？

public class MyTouchListener implements TouchEventHandle {
    @Override
    public boolean onTouchEvent(Component component, TouchEvent touchEvent) {
        int action = touchEvent.getAction();
        if (action == TouchEvent.PRIMARY_POINT_DOWN || action == TouchEvent.POINT_MOVE) {
            int pointerCount = touchEvent.getPointerCount();
            for (int i = 0; i < pointerCount; i++) {
                int x = touchEvent.getPointerPosition(i).getX();
                int y = touchEvent.getPointerPosition(i).getY();
                // 处理触摸坐标
                // ...
            }
        }
        return true;
    }
}

public class MyComponent extends Component {
    public MyComponent() {
        setTouchEventListener(new MyTouchListener());
    }
}
