kv 文件中的按钮不会重定向到所需的页面

Button in kv file doesn't redirect to the desired page

您好,我的代码有问题:正如您在标题中所读到的,我有这个按钮,它应该将用户重定向到另一个页面,但是当点击它时它没有做任何事情。你能帮帮我吗?

这是代码

这里我定义了按钮

<Home>:
    name: "home"

    BoxLayout:
        orientation: "vertical"
        pos_hint: {"center_x": .5}
        size_hint: .7, 1

        Label:
            text: "Home"
            font_size: 50

        Label:
            text: ""

        Button:
            text: "FAQ"
            on_release:
                app.root.current: "FAQ_AP"
                root.manager.transition.direction = "left"

        Label:
            text: ""

        Button:
            text: "Gestionale"
            on_release:

        Label:
            text: ""

我在这里创建了按钮应该重定向到的页面:

<FAQ_AP>:
    name: "FAQ_AP"

    BoxLayout:
        orientation: "vertical"
        pos_hint: {"center_x": .5}
        size_hint: .7, 1

        Label:
            font_size: 50
            text: "Sei un'azienda o un privato?"

        Label:
            text: ""

        Label:
            text: ""

        Button:
            text: "Azenda"
            on_release:

        Label:
            text: ""

        Button:
            text: "Privato"
            on_release:

        Label:
            text: ""

如果你能帮助我,那将是最好的。提前谢谢你。

您无需在按钮的 on_release 功能中提及 .app

用这个,效果很好

Button:
    text: "FAQ"
    on_release:
        root.manager.current = "FAQ_AP"
        root.manager.transition.direction = "left"
