Listview with popup on selection - python-3.x

Question

I am trying to make a listview in which the selected buttons produce a popup with different information depending on which list button was selected. Any suggestions? Thank you

ListView has been deprecated since Kivy version 1.10.0. In the example below, we are using Recycleview.
Example
main.py
from kivy.app import App
from kivy.uix.recycleview import RecycleView
from kivy.uix.recycleview.views import RecycleDataViewBehavior
from kivy.uix.button import Button
from kivy.uix.recycleboxlayout import RecycleBoxLayout
from kivy.uix.behaviors import FocusBehavior
from kivy.uix.recycleview.layout import LayoutSelectionBehavior
from kivy.uix.popup import Popup
from kivy.properties import ListProperty, StringProperty, ObjectProperty
class MessageBox(Popup):
def popup_dismiss(self):
self.dismiss()
class SelectableRecycleBoxLayout(FocusBehavior, LayoutSelectionBehavior, RecycleBoxLayout):
""" Adds selection and focus behaviour to the view. """
selected_value = StringProperty('')
btn_info = ListProperty(['Button 0 Text', 'Button 1 Text', 'Button 2 Text'])
class SelectableButton(RecycleDataViewBehavior, Button):
""" Add selection support to the Label """
index = None
def refresh_view_attrs(self, rv, index, data):
""" Catch and handle the view changes """
self.index = index
return super(SelectableButton, self).refresh_view_attrs(rv, index, data)
def on_press(self):
self.parent.selected_value = 'Selected: {}'.format(self.parent.btn_info[int(self.id)])
def on_release(self):
MessageBox().open()
class RV(RecycleView):
rv_layout = ObjectProperty(None)
def __init__(self, **kwargs):
super(RV, self).__init__(**kwargs)
self.data = [{'text': "Button " + str(x), 'id': str(x)} for x in range(3)]
class TestApp(App):
title = "RecycleView Button Popup Demo"
def build(self):
return RV()
if __name__ == "__main__":
TestApp().run()
test.kv
#:kivy 1.10.0
<MessageBox>:
title: 'Popup Message Box'
size_hint: None, None
size: 400, 400
BoxLayout:
orientation: 'vertical'
Label:
text: app.root.rv_layout.selected_value
Button:
size_hint: 1, 0.2
text: 'OK'
on_press:
root.dismiss()
<SelectableButton>:
# Draw a background to indicate selection
canvas.before:
Color:
rgba: (0.0, 0.9, 0.1, 0.3)
Rectangle:
pos: self.pos
size: self.size
<RV>:
rv_layout: layout
viewclass: 'SelectableButton'
SelectableRecycleBoxLayout:
id: layout
default_size: None, dp(56)
default_size_hint: 0.1, None
size_hint_y: None
height: self.minimum_height
orientation: "vertical"
Output
