Question

我在设置按钮时遇到问题，该按钮在按下时会播放音频。我在按钮上使用tkinter，在音频上使用simpleaudio。

x = ""
def audio(file):
    x = file
    return x
window = tk.Tk()
window.title("Audio")
audio_button = tk.Button(window,text="Audio Test",command=audio("imposter")).pack(side="left")
audio_button1 = tk.Button(window,text="Audio Test Two",command=audio("crewmate")).pack(side="left")
stop_all = tk.Button(window,text="Stop All",command=audio("stop"),fg="red").pack(side="left")
tk.mainloop()
while True:
    if not x == "stop":
        if x == "crewmate":
            wave_obj = sa.WaveObject.from_wave_file("File here")
            play_obj = wave_obj.play()
            while play_obj.is_playing():
                if x == "stop":
                    break
                else:
                pass
        elif x == "imposter":
            wave_obj = sa.WaveObject.from_wave_file("File here")
            play_obj = wave_obj.play()
            while play_obj.is_playing():
                if x == "stop":
                    break
                else:
                    pass
    else:
        pass

也可以帮助缩短代码

Answer 1

pack返回None，因此，当需要保留对小部件的引用时，应将链式打包链接到小部件的创建。

这是解决您问题的一种可能方法；我没有简单的音频，所以不能保证代码完全正确；带有simpleaudio调用的代码行已被注释掉，并且print语句使您可以验证逻辑。您将必须取消注释它们，然后尝试。

逻辑在启动新文件之前停止所有音频；您可能希望使其更加用户友好，例如，如果命令请求同一首歌曲，则让歌曲结束，而不是重新启动它。

# import simpleaudio as sa
import tkinter as tk

def stop_audio():
    print('stopping all')
#   sa.stopall()

def test_audio(state):
    if state == 'imposter':
        path = "path/to/imposter.wav"
    elif state == 'crewmate':
        path = "path/to/crewmate.wav"
    else:
        return
#     wave_obj = sa.WaveObject.from_wave_file(path)
    stop_audio()
#     play_obj = wave_obj.play()
    print(f'playing {state}')
    
window = tk.Tk()
window.title("Audio")

audio_button = tk.Button(window,text="Audio Test", command=lambda state='imposter': test_audio(state))
audio_button.pack(side="left")

audio_button1 = tk.Button(window,text="Audio Test Two", command=lambda state='crewmate': test_audio(state))
audio_button1.pack(side="left")

stop_all = tk.Button(window,text="Stop All",fg="red", command=stop_audio)
stop_all.pack(side="left")

tk.mainloop()
