【问题描述】：
根据输入（0、1、2 或 3），kv.file 或 py.file 应将一组切换按钮添加到现有布局。我尝试了很多，但似乎无法弄清楚并希望得到一些建议，因为这对我来说仍然有点新。
- 所以当 self.reminder() = 0 时，不会显示切换按钮。
- 当 self.reminder() = 1 时，显示一组切换按钮。
- 当 self.reminder() = 2 时，显示两组切换按钮。
- 当 self.reminder() = 3 时，显示三组切换按钮。
- self.reminder() 不会超过 3 的值。
所以我得到了我的 .py 文件
import kivy
from kivy.app import App
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.lang import Builder
import csv
from kivy.core.window import Window
class WindowManager(ScreenManager):
pass
#Backgroundcolour
Window.clearcolor = (0.67, 0.83, 0.88, 1)
class DiaryToday(Screen):
user_id = 3
# reads how many reminders (aka Toggle Buttons) the user wants from csv file
# used for textlabel, this textlabel will not show if reminder == 0 (is stated in kv file)
def reminder(self):
with open('users.csv') as file: #TO DO: needs to be adjusted to global ID
reader = csv.DictReader(file)
for row in reader:
if row['id'] == str(self.user_id): #TO DO: needs to be adjusted to global ID
if row['mood_rem'] == 'Zero':
return(0)
else:
return(row['mood_rem'][0])
# TO DO: STORES in CSV file which emoji you clicked
def mood_value(self, mood):
print (mood)
#Takes care of which group of ToggleButtons is shown in the Diary Screen
def add(self):
if root.reminder() == 0:
#should add or show no Toggle Buttons
if root.reminder() == 1:
#should add or show 1 set of Toggle Buttons
if root.reminder() == 2:
#should add or show 2 sets of Toggle Buttons
if root.reminder()== 3:
#should add or show 3 sets of Toggle Buttons
class LoopApp(App):
def build(self):
return DiaryToday()
if __name__ == '__main__':
LoopApp().run()
还有我的 .kv 文件
