如何解决我正在尝试使添加按钮在kivy中添加另外3个textinput框
对不起，如果某些部分希望使用我的语言，那没关系
当我按下“添加”按钮添加另外3个文本输入（如“添加”按钮上方的那些）时，我想保存输入到这些文本输入框上的输入，但是我想我自己也可以。
我搜索了，但是找不到有用的东西。这也是我第一次在此级别创建某些东西，如果它在某些方面效率低下，请对不起。
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

解决方法
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PartsTextInputs中为kv添加一个规则，并为其中包含一个ScrollView。修改后的kv如下所示：
<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
