我是使用 Kivy 进行 Android 开发的新手。我创建了一个选项卡结构,如下所示:
from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.uix.tabbedpanel import TabbedPanelHeader
from kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.image import Image
class TabbedPanelApp(App):
def build(self):
tb_panel= TabbedPanel()
# Create text tab
th_text_head = TabbedPanelHeader(text='Text tab')
th_text_head.content= Label(text='This is my text content')
# Create image tab
th_img_head= TabbedPanelHeader(text='Image tab')
th_img_head.content= Image(source='sample.jpg',pos=(400, 100), size=(400, 400))
# Create button tab
th_btn_head = TabbedPanelHeader(text='Button tab')
th_btn_head.content= Button(text='This is my button',font_size=20)
tb_panel.add_widget(th_text_head)
tb_panel.add_widget(th_img_head)
tb_panel.add_widget(th_btn_head)
return tb_panel
if __name__ == '__main__':
TabbedPanelApp().run()
我想将登录小部件添加到默认选项卡。登录小部件的代码是:
import kivy
kivy.require('1.0.5')
from kivy.uix.gridlayout import GridLayout
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.widget import Widget
from kivy.properties import ObjectProperty, StringProperty
class loginView(Widget):
status=ObjectProperty(None)
def validate(self,username,password):
print "user - ", username
print "pwd - ", password
if username == password:
print "in if - ", username,password
self.status.text="Login sucess"
#mainClass().run()
else:
self.status.text="Login failed"
class afterLogin(Widget):
def dumb(self):
l = BoxLayout(cols="2")
btn = Button(text="ad")
l.add_widget(btn)
print "flag"
class mainClass(App):
def build(self):
return loginView()
if __name__ == '__main__':
mainClass().run()
kv文件是:
#:kivy 1.0.5
<loginView>:
status:result
Label:
text:"Contacts Manager"
pos:600,600
font_size:40
Label:
text:"Username"
pos:450,400
Label:
text:"Password"
pos:450,300
TextInput:
multiline:False
pos:600,425
size:200,45
font_size:20
id:username
TextInput:
multiline:False
pos:600,325
password:True
size:200,45
font_size:20
id:password
Button:
text:"Login"
size:100,50
pos:600,250
on_press:root.validate(username.text,password.text)
Label:
text:""
pos:600,100
id:result
<afterLogin>:
Label:
text:"Welcome"
如何将此代码添加到默认选项卡中?
