Solution

1. In kv file, add an id: ti to TextInput widget.
2. In Python script, create a custom class of DatePicker and override update_value() method.

Please refer to example for details.

Example

main.py

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from KivyCalendar import DatePicker
from kivy.core.window import Window

Window.clearcolor = (0.5, 0.5, 0.5, 1)


class CustomDatePicker(DatePicker):

    def update_value(self, inst):
        """ Update textinput value on popup close """

        self.text = "%s.%s.%s" % tuple(self.cal.active_date)
        self.focus = False
        App.get_running_app().root.ids.ti.text = self.text


class Calendar(BoxLayout):

    def show_calendar(self):
        datePicker = CustomDatePicker()
        datePicker.show_popup(1, .3)


class Test(App):
    def build(self):
        return Calendar()


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

test.kv

#:kivy 1.11.0

<Calendar>:
    BoxLayout:
        orientation: "vertical"
        padding : 20, 20
        size_hint_y: .5

        Button:
            on_press: root.show_calendar()
            Image:
                y: self.parent.y
                center_x: self.parent.center_x
                allow_stretch: True
                source: 'cross.png'

        TextInput:
            id: ti

<DatePicker>:
    pHint: .3, .3

Output
