Question

我的所有程序都达到了一定程度，而且我的路被它阻挡了。

我的程序在主应用程序中加载了一些启动画面。
根据用户输入，程序加载完全不同的子应用程序。
尝试更改已加载的子应用程序中的屏幕时出现问题

以下是存在问题的代码：

.py文件：

import kivy
kivy.require('1.10.0')

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import Screen, ScreenManager, FadeTransition
from kivy.uix.button import Button
from kivy.uix.label import Label

chClass = ""

class ScreenManage(ScreenManager):
    pass

class Home(ScreenManager):
    pass

class TitleScreen(Screen):
    pass

class GameScreen(Screen):
    pass

class ClassScreen(Screen):
    pass

class Warrior1(Screen):

    def GetChClass(self, ch):
        return ch

    def build(self):
        ExecuteW().run()

class Acrobat1(Screen):

    def GetChClass(self, ch):
        return ch

class Spell1(Screen):

    def GetChClass(self, ch):
        return ch

class HomeScreen(Screen):
    pass

class WarriorStats(Screen):
    pass

class AcrobatStats(Screen):
    pass

class SpellCasterStats(Screen):
    pass

class ExecuteW(App):
    def build(self):
        return Home()

class RevengeApp(App):
    def build(self):
        return ScreenManage()

if __name__ == '__main__':
    print chClass
    RevengeApp().run()

                on_release: chClass = root.GetChClass('Warrior')
                on_release: root.build()

executew.kv：

#: import sm kivy.uix.screenmanager

<Home>:
    transition: sm.FadeTransition()
    HomeScreen:
    WarriorStats:

<HomeScreen>
    name: 'Home'
    AnchorLayout:
        Button:
            text: "Stats"
            on_release: app.root.current = 'WStats'

<WarriorStats>
    name: 'WStats'
    canvas:
        Rectangle:
            size: self.size
            pos: self.pos
            source: "Warrior.jpg"

问题：在executew中单击主屏幕上的统计按钮时，WarriorStats屏幕名为＆＃39; WStats＆＃39;应该加载，但我收到错误＆＃34;没有名称的屏幕＆＃39; WStats＆＃39;＆＃34;

Answer 1

我自己想出的答案



class HomeScreen(Screen):
    def switch(self):
        self.manager.current = "WStats"

class HomeScreen(Screen): def switch(self): self.manager.current = "WStats"

在executew：

<HomeScreen>
    Button:
        text: "Stats"
        on_release: root.switch()

没有名字的屏幕
