我可以从 kivy 中的 kv 在 Recycleview 中添加小部件吗

Question

I'm trying to add Buttons, Labels and Image in a recycleview.But the Screen stayed in black when running the code. I can't see my Buttons. I want this work from my kv.file.. I mean I want to add buttons, labels and images from my kv.file to a Recycleview (Boxlayout or Gridlayout)

from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.boxlayout import BoxLayout
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.config import Config
from kivy.properties import StringProperty
from kivy.uix.recycleview import RecycleView
from kivy.uix.recycleboxlayout import RecycleBoxLayout

Config.set('graphics', 'width', 360)
Config.set('graphics', 'height', 640)
kv= Builder.load_file('test5.kv')


#Define a RecycleView
class RV (RecycleView):
    pass


class AwesomeApp(App):
    def build(self):
        return RV()

if __name__ == '__main__':
    AwesomeApp().run()

kv.file

<RV>:
    viewclass: 'Button'
    RecycleBoxLayout:
        default_size: None,100
        default_size_hint: 1, None
        size_hinty:None
        height: self.minimum_height
        orientation:'vertical'
        Button:
            text:"test1"
        Button:
            text:"test2"
        Label:
            text: "text3"

Answer 1

A couple of things are wrong here.

First you're size_hinty variable should be written size_hint_y .

The second is that your widget properties need to added to RecycleView.data .

Try removing the buttons from the <RV> class in your.kv file and adding self.data to your RV class in your.py file. That is:

class RV(RecycleView):
    def __init__(self, **kwargs):
        super(RV, self).__init__(**kwargs)
        self.data = [{'text': f'test{x}'} for x in range(1, 4)]
