Kivy音量。蟒

Question

当＆＃34; set_volumemore11＆＃34;时，如何显示和设置音量？是按下了吗？

class MainPage(Screen):
    filenamemore11 = 'synth1.wav'
    soundmore11 = ObjectProperty(None, allownone=True)
    volumemore11 = NumericProperty(1.0)

    def openmore1(self, *args):
        self.more11slider = Slider(orientation='horizontal', min=0, max=1, value= self.volumemore11)
        self.more11slider.bind(on_value=self.set_volumemore11(self.value))
        self.add_widget(self.more11slider)

    def playmore11(self, *args):
        if self.soundmore11 is None:
            self.soundmore11 = SoundLoader.load(self.filenamemore11)
        if self.soundmore11.status != 'stop':
            self.soundmore11.stop()
        self.soundmore11.loop = False
        self.soundmore11.volumemore11 = self.volumemore11
        self.soundmore11.play()

    def set_volumemore11(self, volumemore11):
        self.volumemore11 = volumemore11
        if self.soundmore11:
            self.soundmore11.volumemore11 = volumemore11

到目前为止，我已经尝试了所有我知道的内容，包括value= self.soundmore11.volumemore11到on_value=self.set_volumemore11(self.value)，但它仍然无效。任何类型的帮助将不胜感激。

def openmore1(self, *args):
    self.more11slider = Slider(orientation='horizontal',step=0.1, min=0, max=1, value= self.volumemore11)
    self.add_widget(self.more11slider)

def playmore11(self, *args):
    if self.soundmore11 is None:
        self.soundmore11 = SoundLoader.load(self.filenamemore11)
    if self.soundmore11.status != 'stop':
        self.soundmore11.stop()
    self.soundmore11.loop = False
    self.soundmore11.volumemore11 = self.volumemore11
    self.soundmore11.play()

我忘记回答这个问题，但是，她是一个简单的方法......你也可以在按下vol按钮时通过这样做来改变音量。

def set_volumemore11(self, *args):
    self.volumemore11 += 0.2
    if self.volumemore11 ==: 1.2
        self.volumemore11 = 0.0
