HarmonyOS如何增加控件点击热区？

Rect bounds = new Rect(); 
view.setEnabled(true); 
view.getHitRect(bounds); 
bounds.top -= top; 
bounds.bottom += bottom; 
bounds.left -= left; 
bounds.right += right; 
TouchDelegate touchDelegate = new TouchDelegate(bounds, view); 
if (View.class.isInstance(view.getParent())) { 
  ((View) view.getParent()).setTouchDelegate(touchDelegate); 
}
