Question

我正在尝试创建一个需要用户输入坐标的游戏。但是，我意识到即使单击“ Enter”按钮并更改了屏幕，也不会清除这些字段。通常，我通常使用普通的textinput字段插入python行self.shootdepthinput.text=''，这将清除字段中的文本输入，因为它是字符串。但是，对于MDTextField，输入为不可变的元组形式。有人知道我可以清除MDtextfield的功能吗？谢谢！

这是我的kivy文件的摘录，其中在以下位置找到了我的MDTextField：

<ComputerScreen>:

    shootxinput: shootxinput_id
    shootyinput: shootyinput_id
    shootdepthinput: shootdepthinput_id

    id: "computerscreen_id"
    name: "computer"
    canvas.before:
        Rectangle:
            pos: self.pos
            size: self.size
            source: "battleshipgame.png"

    GridLayout:
        cols: 3
        id: s_input
        pos_hint: {"x":0.03,"y":0.72}
        size_hint : 0.7, 0.1

        MDTextField:
            id: shootxinput_id
            hint_text: "X-Coordinate"
            required: True
            helper_text_mode: "on_focus"
            color_mode: "custom"
            helper_text: "Enter a number from 1 to 10"
            line_color_focus: 0, 0, 0, 1

        MDTextField:
            id: shootyinput_id
            hint_text: "Y-Coordinate"
            required: True
            color_mode: "custom"
            helper_text_mode: "on_focus"
            helper_text: "Enter an alphabet from A to J"
            line_color_focus: 0, 0, 0, 1

        MDTextField:
            id: shootdepthinput_id
            hint_text: "Depth"
            required: True
            color_mode: "custom"
            helper_text_mode: "on_focus"
            helper_text: "0: Surface Level, 1: Sub-sea Level"
            line_color_focus: 0, 0, 0, 1

    FloatLayout:
        id: buttonarea
        Button:
            id: shootsubmitbtn
            size_hint:0.1,0.05
            on_press: root.shoot()
            text: "Enter"
            pos_hint:{"x": 0.75, "y": 0.75}

创建一条语句，清除shoot方法内的输入字段

def shoot(self, *args):
    shootxinput_id.text, shootyinput_id.text = ""
    # do some other things

提交后从kivymd清除MDTextField
