我有一个简单的代码，输出类似enter image description here
的内容负责该视图的代码是：
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import kivy
kivy.require('1.9.1')
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.gridlayout import GridLayout
from kivy.uix.textinput import TextInput
from kivy.uix.button import Button
class LoginView():
layout=BoxLayout(orientation="vertical", padding=[50,0])
state="none"
def create(self):
#super(LoginView, self).__init__()
self.layout.add_widget(Label(text='Login'))
self.username = TextInput(multiline=False)
self.layout.add_widget(self.username)
self.layout.add_widget(Label(text='Password'))
self.password = TextInput(password=True, multiline=False)
self.layout.add_widget(self.password)
self.button=Button(text="Let's Go", font_size=20)
self.button.bind(on_release=self.login)
self.layout.add_widget(self.button)
if self.state=="passed":
return self.state
self.status=Label(text='nic') # text for testing. it's like indicator
self.layout.add_widget(self.status) # and I show it
return self.layout
def login(self, somedata):
self.status.text='idzie' # here I change my indicator
somedata.text="xx"
if self.username.text=="non": # here I check username!!
self.layout.add_widget(Label(text="OK!"))
self.state="passed"
虽然这个代码在桌面上工作得很好，但是在Android上我可以点击按钮，当我点击它时它会变成蓝色，但是文本不会像在桌面上那样发生变化。我不知道为什么。它不应该在Android上运行相同吗？ 这是我的buildozer.spec：

# -----------------------------------------------------------------------------
# List as sections
#
# You can define all the "list" as [section:key].
# Each line will be considered as a option to the list.
# Let's take [app] / source.exclude_patterns.
# Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
# This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#
# -----------------------------------------------------------------------------
# Profiles
#
# You can extend section / key with a profile
# For example, you want to deploy a demo version of your application without
# HD content. You could first change the title to add "(demo)" in the name
# and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
答案 0 :(得分：0)
我找到了。实际上我不得不使用LoginView（App）而不是LoginView（）。 但它真的令人困惑，为什么它在桌面上工作..
