我正在尝试让添加按钮在 kivy 中添加另外 3 个文本输入框

Question

很抱歉，如果某些部分是我的语言，希望没关系 当我按下“添加”按钮添加另外 3 个文本输入时，例如“添加”按钮上的那些，我想保存放在这些文本输入框上的输入，但我想我可以自己弄清楚。 我搜索但找不到有用的东西。这也是我第一次在这个级别上创建一些东西，如果它在某些方面效率低下，非常抱歉。 这是py 文件：

from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.properties import ObjectProperty


class MyGrid(GridLayout) :
    id_1 = ObjectProperty(None)
    id_2 = ObjectProperty(None)
    id_3 = ObjectProperty(None)
    id_4 = ObjectProperty(None)
    id_10 =ObjectProperty(None)

    def perfundo (self) :
        file = open('F:\\F\\F\\' + self.id_1.text + '-' + str(date.today()) + '.txt', 'x')
        file.write('Emri dhe mbiemri :' + self.id_1.text + '\n' + 'Lloji i vetures :' + self.id_2.text + '\n' + 'Nr. i telefonit :' + self.id_3.text + '\n' + 'Problemi :' + self.id_4.text)
        file.close()

    def add(self):
       self.id_10.text

class HAZApp(App) :
    def build (self) :
        return MyGrid()


app = HAZApp()
app.run()

这是kv文件

Answer 1

我建议使用ScrollView 来包含TextInputs。您的add() 方法可以是：

def add(self):
    # Add a new PartsTextInputs inside the ScrollView
    self.ids.parts_text_inputs.add_widget(Factory.PartsTextInputs())

然后在kv 和ScrollView 中为PartsTextInputs 添加规则以包含它们。这是修改后的kv 的样子：

<PartsTextInputs@BoxLayout>:  # this is a rule for building the parts TextInputs
    size_hint_y: None
    height: self.minimum_height
    spacing: 20
    TextInput:
        size_hint_y: None
        height: 48
    BoxLayout:
        size_hint_y: None
        height: self.minimum_height
        TextInput:
            size_hint_y: None
            height: 48
        TextInput:
            size_hint_y: None
            height: 48
