我想在按下选择时实现 on_touch_down 功能，但不知道如何实现它

Question

I want when this image in my python file is pushed, I want to use the on_touch_down function instead the on_release function. if anyone could be of any assistance I would appreciate it.

    def __init__(self, **kwargs):
        super(ProfileWindow, self).__init__(**kwargs)
        self.profileimage = ImageButton(source= "icons/profilepic.png", pos_hint={"center_x": 0.5, "center_y": 0.65})
        self.profileimage.bind(on_release= self.imagechange)
        self.add_widget(self.profileimage)

Thanks for future assistance

使用on_press而不是on_release 。
