android - 如何使用 kivy 更改标签的位置

Question

我目前正在编写一个简单的应用程序以在按下按钮后显示一些文本。然而，布局在我的手机上与我的电脑上完全不同。更改 .kv 中标签的位置不起作用；没有改变。为了构建应用程序，我使用带有 buildozer 的 Ubuntu 虚拟机。

    return int(math.ceil(x / 5.0)) * 5

x = random.randint(0,29)

tempo = roundup(random.randint(80,150))

class ActionApp(App):

    def build(self):

myApp = ActionApp()

myApp.run()

动作.kv：

    <Controller>:
    lbl: label1
    lbl2: label2
    lbl3: label3
    lbl4: label4
    lbl5: label5
    lbl6: label6
    RelativeLayout:

        Button:
            text: 'Key und Bpm generieren'
            on_press: root.btn_clk()
            pos: 0,50
        Label:                 
            id: label1
            text: 'Tonart:'
            pos: -158, -272
        Label:
            id: label2
            text: "..."
            pos: -45, -272
        Label:
            id: label3
            text: "also:"
            pos: 40, -272
        Label:
            id: label4
            text: "..."
            pos: 200, -272
        Label:
            id: label5
            text: "Bpm:"
            pos: -360, -272
