There is no "on_double_tap" for a Label, you need to create that method yourself.
There is one for TexInput though and you could look how it's done there in the code.
Also, you need to import the Clipboard into your kv file.

I want to pass to my project_selected function the selected item in my MDDialog after pressing the OK button. But I can't figure out how can I get the value and do this.
I could print the value inside my set_icon funtion in ItemConfirm class, but I don't know whats the better way to pass that value to HomeWindow(Screen) class or if it is possible to call it directly from inside of it once that the ItemConfirm is already called from inside a function that is part of HomeWindow class.
main.py
from kivy.lang import Builder
from kivy.uix.screenmanager import Screen, ScreenManager
from kivymd.app import MDApp
from kivymd.uix.button import MDFlatButton
from kivymd.uix.dialog import MDDialog
from kivymd.uix.list import OneLineAvatarIconListItem
class ItemConfirm(OneLineAvatarIconListItem):
divider = None
def set_icon(self, instance_check):
print(self.text)
instance_check.active = True
check_list = instance_check.get_widgets(instance_check.group)
for check in check_list:
if check != instance_check:
check.active = False
class HomeWindow(Screen):
dialog = None
def show_confirmation_dialog(self):
projects = [{id: 0, name: "example1"},{id: 1, name: "example2"}]
if not self.dialog:
self.dialog = MDDialog(
title="Projects",
type="confirmation",
auto_dismiss=False,
items=[ItemConfirm(text=f"{project['name']}") for project in projects],
buttons=[
MDFlatButton(text="CANCEL", theme_text_color="Custom"),
MDFlatButton(
text="OK",
theme_text_color="Custom",
on_release=self.project_selected,
),
],
)
self.dialog.open()
def project_selected(self, *args, **kwargs):
self.ids.project_selection.text = self.dialog.text
class WindowManager(ScreenManager):
pass
class RlogTimer(MDApp):
def build(self):
self.theme_cls.theme_style = "Dark"
self.theme_cls.primary_palette = "BlueGray"
self.root = Builder.load_file("templates/main.kv")
return self.root
if __name__ == "__main__":
RlogTimer().run()
templates/main.kv
#: import NoTransition kivy.uix.screenmanager.NoTransition
WindowManager:
HomeWindow:
<ScreenManager>:
transition: NoTransition()
<ItemConfirm>:
on_release: root.set_icon(check)
CheckboxLeftWidget:
id: check
group: "check"
<HomeWindow>:
name: "home"
MDBoxLayout:
orientation: "vertical"
MDToolbar:
id: title
title: "Redmine logTimer"

MDFlatButton:
id: project_selection
text: "Select Project"
pos_hint: {'center_x': .5, 'center_y': .5}
on_release: root.show_confirmation_dialog()
You can achieve that as follows,
First create a prop. say, selected_project in HomeWindow as,
class HomeWindow(Screen):
dialog = None
selected_project = StringProperty()
Now set its value in method set_icon as,
def set_icon(self, instance_check):
...
app = MDApp.get_running_app() # Access the running app instance.
home_screen = app.root.get_screen("home") # Access required screen.
home_screen.selected_project = self.text # Now set value.
...
Now it's time to set this value in method project_selected,
def project_selected(self, *args, **kwargs):
self.ids.project_selection.text = self.selected_project
anyone can help me about how to add KivyMD Expansion Panel in RecycleView kivy? Because I have issue with slow perfomance while add MDExpansionPanel with "add_widget" on kivy (run in old android).

From my understanding , if you are trying to add your expansion panel inside the RecycleView.
Here is an example code of how to do that

from kivymd.uix.expansionpanel import MDExpansionPanel, MDExpansionPanelThreeLine
from kivymd import images_path

secondary_text: "Mobile"
RecycleView:
MDGridLayout:
id: box
cols: 1
adaptive_height: True
"""
class Content(MDBoxLayout):
"""Custom content."""
class Test(MDApp):
def build(self):
return Builder.load_string(KV)
def on_start(self):
for i in range(10):
self.root.ids.box.add_widget(
MDExpansionPanel(
icon=f"{images_path}kivymd.png",
content=Content(),
panel_cls=MDExpansionPanelThreeLine(
text="Text",
secondary_text="Secondary text",

),
)
)

I've put a loop into thread and I want my label to show the given thext. The issue is that it doesn't show most of texts I see in the terminal. It shows only:
>Text 0
>nothing
>Text 4
>Text 5
>nothing
>text 14
>text 15
>etc.
I've no idea why is that. I tried to use Clock.schedule_once to call prompt function but the resoult is the same.

Try adding the #mainthread decorator to the prompt() method. Changes to the GUI must be done on the min thread.

I am trying to inherit from ScreenManager, but it is giving the 'super' attribute error. Tried passing id as argument in the .kv and tried to find real parent but nothing works.
Also, please suggest how to use the above code for recycle GridLaout, with 2d rows and columns, i tried using for loops, but getting key related errors.
like:
for z in range(12):
for y in range(8):
self.table_data12.append(self.ids.idname.data[y][z]['text'])
thanks!
In your DataView class, the __init__() method references self.ids, but the ids are not yet available at that point. You can delay that referencing by using Clock.schedule_once() like this:
def __init__(self, *args, **kwargs):
super(DataView, self).__init__(*args, **kwargs)
# for key, val in self.ids.items():
# print("key={0}, val={1}".format(key, val))
Clock.schedule_once(self.setup_data)
def setup_data(self, dt):
data12 = []
for x in range(self.TextInputNum):
data12.append({'text': '', 'height': 50})
self.ids.rv.data = data12
I see no reason for making the RecycleItem a subclass of ScreenManager.
In your 'kv, the on_textline forRecycleItem` can be:
<RecycleItem>:
on_text: app.root.get_screen('DataView_screen').ids.rv.data[self.index]['text'] = self.text
And the submit Button can be:
Button:
text: 'Submit'
size_hint_y: 0.1
on_release: root.extract_data(rv)
I made an app working with kivy that sends "name" to the server(with socket), the server inserts the "name" to the data base and sends back the "name" to the client(the app) and the client prints it.

Can you help me?
The problem is as you mentioned the recv method.
That method put the whole main thread on hold, so the app wont run.
Whenever something is waiting or looping in the mainthread, the app will stop updating. And recv is waiting for a message.
So you need to put the recv in a thread.
You could do like this:
import threading
from kivy.clock import mainthread
class Searchi(Screen):
def __init__(self, **kwargs):
super(Searchi, self).__init__(**kwargs)
self.hello_label = Label(text="Connecting...",size_hint=(1,1.7),font_size=20)
threading.Thread(target=self.recv_msg).start()
# make sure you execute UI updates in mainthread
#mainthread
def recv_msg(self):
self.my_socket = socket.socket()
self.my_socket.connect(('127.0.0.1', 8081))
self.msg=self.my_socket.recv(1024)
self.name=self.msg.decode('utf-8')
self.hello_label.text = "hello"+self.name
