我正在尝试在浮动布局区域中创建一个复选框。我正在生成复选框，但每次单击它都会从 True 变为 False，即使它不在框中。有人可以提供一些见解吗？

我的代码：

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.checkbox import CheckBox
from kivy.uix.floatlayout import FloatLayout
from kivy.uix.screenmanager import ScreenManager, Screen, NoTransition
from kivy.uix.textinput import TextInput
from kivy.uix.widget import Widget


#######``Windows``#######
class MainScreen(Screen):
    pass

class AnotherScreen(Screen):
    def add(self, *args):
        a = self.ids["a"].text
        a = int(a)
        self.ids["adds"]
        plus = 1 + a
        print plus

class ScreenManagement(ScreenManager):
    pass


presentation = Builder.load_file("GUI_Style.kv")

class MainApp(App):
    def build(self):
        return presentation

if __name__ == "__main__":
    MainApp().run()

我的 KV 文件：

#: import NoTransition kivy.uix.screenmanager.NoTransition

ScreenManagement:
    transition: NoTransition()
    MainScreen:
    AnotherScreen:

<MainScreen>:
    background_color: 0.5, 1, 0.22, 1
    name: "main"
    FloatLayout:
        Button:
            text: "Quit"
            font_size: 50
            color: 0,1,0,1
            font_size: 25
            size_hint: 0.3,0.2
            pos_hint: {"x":0, "y":0}
            on_release: app.window().stop()
        Button:
            on_release: app.root.current = "other"
            text: "Next Screen"
            font_size: 50
            color: 0,1,0,1
            font_size: 25
            size_hint: 0.3,0.2
            pos_hint: {"right":1, "top":1}

<AnotherScreen>:
    name: "other"
    canvas.before:
        Color:
            rgba: 1, 1, 1, 1
        Rectangle:
            pos: self.pos
            size: self.size
    FloatLayout:
        CheckBox:
            pos_hint: {"x":0.2, "y":0.2}
            on_release: True
        TextInput:
            id: a
            font_size: 25
            password: True
            pos_hint: {"x":0.5, "y":0.5}
            size_hint: 0.3,0.2
            text: "Insert Side A here"
        Button:
            id: adds
            background_color: 0,0,1,1
            color: 0,1,0,1
            font_size: 25
            on_release: root.add()
            pos_hint: {"x":0, "y":0}
            size_hint: 0.3,0.2
            text: "plus"
        Button:
            color: 0,1,0,1
            background_color: 0,0,1,1
            font_size: 25
            size_hint: 0.3,0.2
            text: "Back Home"
            on_release: app.root.current = "main"
            pos_hint: {"right":1, "top":1}

尝试将 CheckBox 放在小部件中，它可以工作。我是说：

FloatLayout:
    Widget:
        CheckBox:
            pos_hint: {"x":0.2, "y":0.2}
            on_release: True
    TextInput:
        id: a
        font_size: 25
        password: True
        pos_hint: {"x":0.5, "y":0.5}
        size_hint: 0.3,0.2
        text: "Insert Side A here"
    Button:
        id: adds
        background_color: 0,0,1,1
        color: 0,1,0,1
        font_size: 25
        on_release: root.add()
        pos_hint: {"x":0, "y":0}
        size_hint: 0.3,0.2
        text: "plus"

当然它会破坏您的布局，但它可以解决您遇到的问题。
