Question

我有一个应用程序，将来会成为纸牌游戏计数器，但是现在它还远不及那个阶段，反正我有3个文件，main.py，screens.kv，screens2.kv（没有里面有任何东西）现在我也得到了一张图片，还有一个按钮，每次按下它时，为了进行测试，它都会写下“按下”，我已经呆了至少2个小时，无法弄清楚如何制作当我按下“开始Pasmar”时按钮出现（Pasmar是将来的游戏名称），它所显示的只是在按下按钮后出现空白屏幕，但我确实将它们替换了，并且只显示了按钮，没有其他显示。

这是我当前的代码：

    pass


class ScreenTwo(Screen):

    def __init__(self, **kwargs):
        super(ScreenTwo, self).__init__(**kwargs)


class RootWidget(FloatLayout):
    pass

class ImageButton(ButtonBehavior, Image):  
    def on_press(self):
        print ('pressed')


    def displayScreenThenLeave(self):
        self.changeScreen()

    def changeScreen(self):
        if self.manager.current == 'screen1':
            self.manager.current = 'screen2'
        else:
            self.manager.current = 'screen1'


class Manager(ScreenManager):

    screen_one = ObjectProperty(None)
    screen_two = ObjectProperty(None)


class ScreensApp(App):

    def build(self):
        m = Manager(transition=NoTransition())
        return m

if __name__ == "__main__":
    ScreensApp().run()
class The_AssignmentApp(App):  
    def build(self):  
        return RootWidget()
if __name__ == "__main__":
    The_AssignmentApp().run()

这是kv文件：

#:kivy 1.10.1

<ScreenOne>:

    BoxLayout:
        orientation: "vertical"
        size: root.size
        spacing: 15                
        padding: 200


        Label:
            font_size: 34
            text: "Pasmar"
        Button:
            background_color: 0, 255, 0, .255
            text: "Start Pasmar"
            on_release: root.manager.current = "screen2"

<ScreenTwo>:        

    BoxLayout:
        orientation: "vertical"
        size: root.size
        spacing: 20
        padding: 20


<Manager>:
    id: screen_manager

    screen_one: screen_one
    screen_two: screen_two

    ScreenOne:
        id: screen_one
        name: "screen1"
        manager: screen_manager

    ScreenTwo:
        id: screen_two
        name: "screen2"
        manager: screen_manager

Kivy将图像作为按钮添加到另一页
