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

如果某些部分在我的语言中，我很抱歉，希望这无关紧要当我按下"添加"按钮再添加3个文本输入时，就像"添加"键上的输入一样，我想保存这些文本输入框上的输入，但我想我自己可以解决。我搜索了一下，但找不到有用的东西。这也是我第一次创建这个级别的东西，如果在某些方面效率低下，我很抱歉。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

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中为PartsTextInputs添加一个规则，并添加一个包含它们的ScrollView。以下是修改后的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
