一、环境设置
第一步引入必须的各类包
import os import tkinter import tkinter.filedialog import random import time import threading import pygame
特别是pygame需要手动安装
pip install pygame
二、播放功能
首先选择音乐目录，然后创建播放现成，播放音乐。
# 播放按钮 def buttonPlayClick(): # 选择要播放的音乐文件夹 global folder if not folder: folder = tkinter.filedialog.askdirectory() if not folder: return global playing playing = True # 创建一个线程来播放音乐，当前主线程用来接收用户操作 t = threading.Thread(target=play) t.start() # 根据情况禁用和启用相应的按钮 buttonPlay['state'] = 'disabled' buttonStop['state'] = 'normal' buttonPause['state'] = 'normal' buttonNext['state'] = 'normal' pause_resume.set('Pause') buttonPlay = tkinter.Button(root, text='Play', command=buttonPlayClick) buttonPlay.place(x=20, y=10, width=50, height=20)
三、停止功能
很直接，直接停止播放，当然更改按钮状态也属常规操作。
def buttonStopClick(): global playing playing = False pygame.mixer.music.stop() musicName.set('暂时没有播放音乐') buttonPlay['state'] = 'normal' buttonStop['state'] = 'disabled' buttonPause['state'] = 'disabled' buttonNext['state'] = 'disabled' global folder folder = '' buttonStop = tkinter.Button(root, text='Stop', command=buttonStopClick) buttonStop.place(x=80, y=10, width=50, height=20) buttonStop['state'] = 'disabled'
三、暂停与恢复
这个好理解，也是直接现成操作，加个判断，状态更改。
# 暂停与恢复，两个功能共用一个按钮 def buttonPauseClick(): # global playing if pause_resume.get() == 'Pause': pygame.mixer.music.pause() pause_resume.set('Resume') elif pause_resume.get() == 'Resume': pygame.mixer.music.unpause() pause_resume.set('Pause')
四、关闭
先结束现成，然后关闭窗体。
# 关闭程序时执行的代码 def closeWindow(): # 修改变量，结束线程中的循环 global playing playing = False time.sleep(0.3) try: # 停止播放，如果已停止， # 再次停止时会抛出异常，所以放在异常处理结构中 pygame.mixer.music.stop() pygame.mixer.quit() except: pass root.destroy()
五、成品代码。
#!/usr/bin/python # -*- coding: UTF-8 -*- """ @author:livingbody @file:music_play.py @time:2022/04/19 """ import os import tkinter import tkinter.filedialog import random import time import threading import pygame folder = '' def play(): # folder用来表示存放MP3音乐文件的文件夹 global folder musics = [folder + '\' + music for music in os.listdir(folder) \ if music.endswith(('.mp3', '.wav', '.ogg'))] # 初始化混音器设备 pygame.mixer.init() while playing: if not pygame.mixer.music.get_busy(): # 随机播放一首歌曲 nextMusic = random.choice(musics) musicName.set('playing....' + nextMusic) pygame.mixer.music.load(nextMusic.encode()) # 播放一次 pygame.mixer.music.play(1) else: time.sleep(0.3) root = tkinter.Tk() root.title('音乐播放器v1.0') root.geometry('280x70+400+300') root.resizable(False, False) # 关闭程序时执行的代码 def closeWindow(): # 修改变量，结束线程中的循环 global playing playing = False time.sleep(0.3) try: # 停止播放，如果已停止， # 再次停止时会抛出异常，所以放在异常处理结构中 pygame.mixer.music.stop() pygame.mixer.quit() except: pass root.destroy() root.protocol('WM_DELETE_WINDOW', closeWindow) pause_resume = tkinter.StringVar(root, value='NotSet') playing = False # 播放按钮 def buttonPlayClick(): # 选择要播放的音乐文件夹 global folder if not folder: folder = tkinter.filedialog.askdirectory() if not folder: return global playing playing = True # 创建一个线程来播放音乐，当前主线程用来接收用户操作 t = threading.Thread(target=play) t.start() # 根据情况禁用和启用相应的按钮 buttonPlay['state'] = 'disabled' buttonStop['state'] = 'normal' buttonPause['state'] = 'normal' buttonNext['state'] = 'normal' pause_resume.set('Pause') buttonPlay = tkinter.Button(root, text='Play', command=buttonPlayClick) buttonPlay.place(x=20, y=10, width=50, height=20) # 停止按钮 def buttonStopClick(): global playing playing = False pygame.mixer.music.stop() musicName.set('暂时没有播放音乐') buttonPlay['state'] = 'normal' buttonStop['state'] = 'disabled' buttonPause['state'] = 'disabled' buttonNext['state'] = 'disabled' global folder folder = '' buttonStop = tkinter.Button(root, text='Stop', command=buttonStopClick) buttonStop.place(x=80, y=10, width=50, height=20) buttonStop['state'] = 'disabled' # 暂停与恢复，两个功能共用一个按钮 def buttonPauseClick(): # global playing if pause_resume.get() == 'Pause': pygame.mixer.music.pause() pause_resume.set('Resume') elif pause_resume.get() == 'Resume': pygame.mixer.music.unpause() pause_resume.set('Pause') buttonPause = tkinter.Button(root, textvariable=pause_resume, command=buttonPauseClick) buttonPause.place(x=140, y=10, width=50, height=20) buttonPause['state'] = 'disabled' # 下一首音乐 def buttonNextClick(): global playing playing = False pygame.mixer.music.stop() pygame.mixer.quit() buttonPlayClick() buttonNext = tkinter.Button(root, text='Next', command=buttonNextClick) buttonNext.place(x=200, y=10, width=50, height=20) buttonNext['state'] = 'disabled' musicName = tkinter.StringVar(root, value='暂时没有播放音乐...') labelName = tkinter.Label(root, textvariable=musicName) labelName.place(x=0, y=40, width=270, height=20) if __name__ == '__main__': # 启动消息循环 root.mainloop()
六、改进
下一步，可加入播放列表，点选播放音乐，也可以拖动进度播放。
