kivy python弹出数据库中的特定项目

Question

所以我正在使用Kivy用Python构建一个基本名称和注释器（本身的一个档案）。我很好奇如何能够点击名称并提供更多信息（关于此人的注释）。我看到了CustomPopup（）功能，但这似乎更具体到一个设置项，而我希望能够点击任何名称并让注释可见。只是朝着正确方向迈出了一步，谢谢你。

这里有一些代码，我对编程非常陌生，所以这几乎是从Derek Banas中剔除，以满足我目前的需求。

Python方面：

from kivy.app import App  
from kivy.uix.boxlayout import BoxLayout  
from kivy.properties import ObjectProperty  
from kivy.uix.listview import ListItemButton  
from kivy.uix.popup import Popup  

class HumanListButton(ListItemButton):  
    pass  

class CustomPopup(Popup):  
    pass  


class HumanDB(BoxLayout):  
    first_name_text_input = ObjectProperty()  
    last_name_text_input = ObjectProperty()  
    notes_input = ObjectProperty()  
    human_list = ObjectProperty()  

    def submit_human(self):  
        # get the human name from textinput, synatx is to use varriable of the textinput.text  
        human_name = self.first_name_text_input.text + " " + self.last_name_text_input.text + " Notes: " + self.notes_input.text  
        # add to list view  
        self.human_list.adapter.data.extend([human_name])  
        # reset the listview, this makes sure it gets updated  
        self.human_list._trigger_reset_populate()  


    def delete_human(self):  
# this is where banas talks about building a database  
# if a list item is selected  
    if self.human_list.adapter.selection:  
    # get the text from the item selected  
        selection = self.human_list.adapter.selection[0].text  
    # remove the matching human  
        self.human_list.adapter.data.remove(selection)  
    # reset the listview  
        self.human_list._trigger_reset_populate()  


def replace_human(self):  

# if a list item is selected  
    if self.human_list.adapter.selection:  
    # get the human name from textinput  
        selection = self.human_list.adapter.selection[0].text  

    # remove matching item  
    self.human_list.adapter.data.remove(selection)  

    # get the huamn name from TextInputs  
        human_name = self.first_name_text_input.text + " " + self.last_name_text_input.text + " Notes: " + self.notes_input.text  
    # add the updated data to the list  
        self.human_list.adapter.data.extend([human_name])  
    # reset the listview  
        self.human_list._trigger_reset_populate()  

def open_popup(self):  
    the_popup = CustomPopup()  
    the_popup.open()  

class HumanDBApp(App):  
    def build(self):  
        return HumanDB()  


dbApp = HumanDBApp()  
dbApp.run()

建议

使用名称的RecycleView。单击任何名称时，使用该人员的注释填充Popup小部件的内容。

  

自版本1.10.0后不推荐使用：ListView已被弃用，请使用   而是RecycleView。
