Kivy 使用触摸屏调用两次功能，但使用鼠标则不行

Question

我正在一个学校项目中，在 Rasp pi 4 Model B 上使用 kivy。

当我使用鼠标（使用 vnc）时，函数 get 调用一次，但当我使用触摸屏时，函数 get 调用两次。

我已经尝试对我的 kivy config.ini 进行一些修改，但没有任何效果。

我的Python代码：

class WindowAdminConfigLockerESPAdd(Screen):
    global deviceLocalName
    number = ''

    def on_enter(self):
        self.ids.TxtAdminConfigLockerESP.text= 'Ajouter des casiers à l ' + deviceLocalName
        pass

    def clearTxt(self):
        self.ids.TxtPin.text=''
        pass

    def PressedButton(self,button):
        print("Appel fonction")
        self.ids.TxtPin.text = self.ids.TxtPin.text + str(button)
        self.number = self.number + str(button) 
        pass

    def Validate(self):
        if(nlc.addNumberLockersConfig(deviceLocalName,self.number)):
            nlc.saveNumberLockersConfigFile()
        self.clearTxt()
    pass

class FenetreManager(ScreenManager):
    pass

kv = Builder.load_file("monkv.kv")

class MonApplicationPrincipale(App):
    def build(self):
        Window.clearcolor = (223/255,223/255,223/255,1)
        return kv

    

if __name__=="__main__":
    MonApplicationPrincipale().run()

我的.kv部分

该函数只需调用一次，因为如果您尝试输入“67”，则输入“6677”。

如果有人知道的话

谢谢，

我并没有真正找到解决方案，我只是进入了ubuntu桌面。但如果有人找到想法或解决方案，我想要它。

Answer 2

我的问题是 KIVY 配置中的这一行。

鼠标=鼠标

当我使用 sudo python3 而不是 python3 来执行代码时，KIVY 配置使用的是 admin 配置而不是 usr 配置。

因此，使用该命令，我更改了管理 KIVY 配置

sudo su
cd /root/.kivy
nano config.ini
