Membuat Aplikasi Android dengan Python dan Kivy | Halaman Profil Member untuk Update Data

Halo, para pejuang bug dan error! 😄
Kali ini kita bakal ngulik gimana caranya bikin halaman profil member di aplikasi Android, tapi bukan pake Java yang bikin kepala ngebul—kita pakai Python + Kivy yang lebih santuy dan ringan.

Di sini, pengguna bisa lihat dan update data mereka sendiri, biar aplikasi kamu makin interaktif dan kelihatan profesional. Gak cuma buat belajar, tapi siapa tahu jadi jalan ninja jadi developer beneran, kan?

Langsung saja. 

tambahkan baris kode di main.py yang berada di BlajarKivy - main.py berikut kodenya

from kivymd.app import MDApp
from kivymd.uix.screenmanager import ScreenManager
from kivy.core.text import LabelBase
from kivy.core.window import Window

Window.size = (500, 650)

from screens.screens import *

class WindowManager(ScreenManager):
	pass

class LapakNgoding(MDApp):
	def build(self):
		self.logged_user = None
		
		self.wm = WindowManager()
		screens =[
			Hallog(name="hallog"),
			Daftar(name="daftar"),
			Hallogadmin(name="hallogadmin"),
			Beranda(name='beranda'),
			Profil(name='profil'), #tambahkan ini
		]
		for screen in screens:
			self.wm.add_widget(screen)
		return self.wm
	
	def logout(self):
		self.wm.current = "hallog"
		
	def profil(self):
		self.wm.current = "profil" #tambahkan ini

if __name__ == '__main__':
	LabelBase.register(name="Atma", fn_regular="kv/assets/fonts/Atma-Bold.ttf")
	LabelBase.register(name="Tagline", fn_regular="kv/assets/fonts/Ubuntu-LI.ttf")
	LabelBase.register(name="Line", fn_regular="kv/assets/fonts/Ubuntu-M.ttf")
	LapakNgoding().run()

 dan jangan lupa tambahkan juga baris kode import di screens.py yang berada di BelajarKivy - screens - screens.py berikut kodenya

from screens.hallog import Hallog
from screens.daftar import Daftar
from screens.daftaradm import DaftarAdm
from screens.beranda import Beranda
from screens.hallogadmin import Hallogadmin
from screens.profil import Profil #tambahkan ini

lalu buat 2 buah file

1. profil.py berada di folder  BelajarKivy - screens - profil.py

        try:

            c = conn.cursor()

            result = c.fetchone()
            conn.close()

            conn.commit()
            conn.close()

            self.dialog = MDDialog(text="Data berhasil diperbarui!", radius=[20, 7, 20, 7])
            self.dialog.open()
        except Exception as e:
