Kivy RecycleView - Kivy Tutorial #12

[@merv893]

Wow your doing all this after your school homework, you have got a great future.

[@snamone]

Ok, I completely prejudged you and I am sorry. I see so many kids o KZbin doing horrible programming videos there friends. As soon as I see someone who looks young I just scroll by. Well I am glad I didn't scroll by, that was an awesome video! One of the best I have seen explaining a Kivy related topic. Thank You!

[@ShawCode]

:D

[@tahep3906]

Thanks a lot for clarifying this seemingly complex widget use, I've seen its usage when taking a look at examples of KivyMd but I couldn't understand what's going on, it seems very powerful and we can do some great things with it I believe, thanks for the video

[@ShawCode]

Thanks! I wasn't sure if I had explained it well enough, but it's great that you understood!

[@mikewesselhoff439]

Thank you for doing this Kivy series. It's very helpful.

[@ShawCode]

Glad you like them!

Hi, just out of curiosity can Recycle view class to definition ? can't find any absolute example

How can we keep this list in sync with a data object? So if I add another item to the list on another layout, this list view will reflect the new elements when I navigate back to this view?

[@joinpsye7045]

It's much more complicated to set events for each of those buttons. And I need help to find how.

[@Uploadnamess]

Hello i have a problem a wanna make a simple app with kivy. When i opened app then i clicked button program has launching on the background and have to take screenshoot for detect something on the screen ,that is posible ?

[@ShawCode]

I don't really understand what you are asking. Please could you clarify what you mean?

[@Uploadnamess]

@@ShawCode Think of an application, this application will run in the background and take a screenshot and examine the picture so that if the color I want is in the picture, it will click on it. With Kivy

[@ShawCode]

@@Uploadnamess I don't think that's possible

[@JuicedApple]

Cool vid👍😁

[@ShawCode]

Thanks!

[@maroso_]

Hi how would you remove buttons on click?

[@ShawCode]

Check this link out: stackoverflow.com/questions/29660632/removing-images-on-clicks-in-kivy It is for images, but the same concept still applies to buttons as well!

[@itspandapo]

Hello @ShawCode I am a Android app developer ! I'm using kivy for my android app development ! So I need to understand recyclerview in kivy, I know you have already uploaded a video of recyclerview, but i need complete knowledge of kivy recyclerview. Such as adding data to recyclerview, update recyclerview, using multiple data in it. Can you please help me ?

[@llewellynvanwyk2282]

Hi how would you style the buttons? say like when i click one on the list the opacity changes or color? Cool video man

[@ShawCode]

Thanks! If you want to modify the appearance of any widget, you're best looking at the documentation (there are loads of different properties that change the appearance, I can't really cover them all in a video). Here's the documentation for the button kivy.org/doc/stable/api-kivy.uix.button.html

nice job

[@ShawCode]

Thanks!

Code runs without error, but only shows black screen with no button widgets. Any ideas why that might be?

[@ShawCode]

Could you please copy and paste your code for me to look at?

[@ShawCode]

@@petelogiudice8202 It isn't working because you haven't linked the kv file properly. It needs to be called the same thing as your App class, without the 'app' on the end. So it should be called my.kv. Let me know if you have any other problems!

[@petelogiudice8202]

@@ShawCode Thanks! I thought I had it named right, but just getting started, so obviously noob mistake. Works now.

PLEASE HELP!!!!!! Hey bro, I am confused on how to make a list that is not visible on the app but it generates and item when a button is. Can you please help me make that?? If you still respond

[@ShawCode]

The next video in the series shows you how to do that!

[@nikhil5387]

hey bro!, please make a video on how to setup Python in Sublime Text 3, I am struggling to setup it. ;(

[@nikhil5387]

print('pls pls pls pls')

[@abduksam]

Just install python and sublime text and you press ctrl + b to run the file

[@ShawCode]

I might make a video in the future on how to do it, but as long as you have python installed and you have selected it in sublime text, then you should be able to use it. You can always take a look at a guide online on how to do it!

[@SusanAmberBruce]

I watched all your tutorials up to #12 and I installed kivy in anaconda3 and copied your code and when I run it I get a window with no widgets and it doesn't respond on closing it and needs forced closing by windows OS. Any clue why? I can run it from anaconda prompt with: python file_name.py (Ex: python javatpoint.py) same thing no widgets but at least it will close without trouble

[@ShawCode]

Sorry, I don't know much about anaconda. I guess you could just run your kivy apps normally, without anaconda?

[@SusanAmberBruce]

@@ShawCode Yep exactly what I been doing, thanks for the tutorial, you have a real talent there!

Hey there Lovely tutorials i just need a favor.. i have python 3.9.1 and when i write pip install pygame the cmd shows that is is successfully installed. Where as when I go to Visual Studio code and write import Pygame it shows an error

[@ShawCode]

Try and see if you can import pygame in IDLE, and then we'll know if it's an issue with VS Code

[@hryanmahajan4264]

Ok i will try thanks for the help :)

hey bro !, good job, I have a problem, how we can add values to recycle view with screen manager ?

[@ShawCode]

If you follow the tutorial covering the screen manager, all you have to do is treat the recycleview like any other widget, and then add it to the screen manager!

Is kivy used for games

[@abduksam]

Yes you can see build with python kivy tutorials

[@ShawCode]

Kivy can be used for games. They are usually done with the Kivy Canvas that I showed you how to use in the 7th tutorial of the series

Hi Shawcode, I wanted to start using your kivy tutorial to create a python app, however whenever I try to do the code it comes up with the error : ImportError: cannot import name 'app' from 'kivy.app' Please help, also keep up the great work with the tutorial these are the best on KZbin

Okay I just changed the word app to App and the word label to Label, seems to be working!! thank you so much for these videos shawn, keep it up

Bro how to get pressed value from list?

[@ShawCode]

You would need your list to be buttons. They would need to have on_press events. You would also need to use an ObjectProperty to access the button from the python file. Let me know if you need any more help!
