Question

有人可以告诉我如何在此代码中使用滚动条吗？其次，有没有办法对齐标签和TextInput，这样无论输入多少，TextInput中的文本都会清晰可见。这里的对齐意味着：如果有100个（数百或数千个）TextInput，TextInput中的文本应该是正确可见的。实际上，当我在代码中给出一些（间距= 50）时，在输入20秒后，文本显示不正确。提前致谢。

要遵循的步骤是：

将ScrollView添加到TabbedPanelItem并将Table放入其中。
使用Table阻止boxlayout（size_hint_y = None）自动调整其高度到其父窗口小部件的高度。
指定Row身高。

代码可以是：

from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import StringProperty
from kivy.uix.textinput import TextInput
from kivy.uix.checkbox import CheckBox
from kivy.lang import Builder

ROWS = ['Goc', 'COC', 'EEE', 'abs' , 'kju' , 'iop' , 'nmg', 'gty', 'jkio', 'dbkgcd' , 'udbcbjkb']

Builder.load_string("""

<Test>:
    do_default_tab: False

    TabbedPanelItem:
        text: 'page1'

        ScrollView:
            Table:
                orientation: "vertical"
                size_hint_y: None
                height: self.minimum_height
                padding: 50, 50, 50, 50


<Row>:
    spacing: 50
    size_hint_y: None
    size_hint_x: 1
    height: 100
    txt: txtinpt.text
    Label:
        text: root.txt

    TextInput:
        id: txtinpt
        text: root.txt
        disabled: not CheckBox.active
    CheckBox:
        id:CheckBox 
        text: 'CheckBox'
        active: False
    Button:
        text: 'save'

""")
class Table(BoxLayout):
    def __init__(self, **kwargs):
        super(Table, self).__init__(**kwargs)
        for row in ROWS:
            self.add_widget(Row(row))



class Row(BoxLayout):
    txt = StringProperty()
    def __init__(self, row, **kwargs):
        super(Row, self).__init__(**kwargs)
        self.txt = row


class Test(TabbedPanel):
    pass

class MyApp(App):

    def build(self):
        test = Test()
        return test


if __name__ == '__main__':
    MyApp().run()
