1、准备工作

ide：pycharm
python：3.7
三方包：pygame、pyinstaller、mutagen
几首mp3格式的歌

2、开始

2.1 设计说明

1、包含 上一首、下一首、暂停/播放、快进/快退、显示当前播放的歌曲名称、显示播放进度条
2、使用pygame.mixer
3、随机播放磁盘某个目录及其子目录下的mp3文件
4、上一首、下一首用随机选择choice(list) 实现
5、进度条用按照一定速度移动进度图片来实现，过程中处理暂停、快进
6、歌曲快进播放用pygame.mixer.music.play(0,d_song_time) 实现
7、暂停用pygame.mixer.music.pause() 实现
8、播放用pygame.mixer.music.unpause() 实现
9、用mutagen.mp3来获取mp3信息

2.2 代码逻辑

收集某个目录下的所有mp3

# 收集某个目录及子目录下的MP3格式的文件# 返回歌曲路径、歌曲时长# [['E:\\musics\\Mirror_Yohee_128K.mp3', 236], ['E:\\musics\\over here_Nobigdyl_128K.mp3', 188], ['E:\\musics\\尘_薛之谦_128K.mp3', 282], ['E:\\musics\\aaa\\尘_薛之谦_128K.mp3', 282]]def collect_songs(fidir):  musics =[]  for root, dirs, files in os.walk(fidir):    for file in files:      tmp =[]      if file.endswith('mp3'):        file = os.path.join(root,file)        song = MP3(file)        duration = round(song.info.length)        tmp.append(file)        tmp.append(duration)        musics.append(tmp)  return musics

显示歌曲名称

# 把歌曲名字显示在播放器上def draw_song_name(music):  # 取歌曲名  music_name = music[0].split("\\")[-1]  # print(music_name)  wbk_obj = font_obj.render(music_name, True, (0, 255, 255))  k_obj = wbk_obj.get_rect()  k_obj.center = (340, 200)  screen.blit(wbk_obj, k_obj)  pygame.display.update()

播放歌曲

# 随机播放一首歌def sing_a_song(musics):  # 随机选择一首音乐  music = choice(musics)  print(type(musics))  pygame.mixer.music.load(music[0])  pygame.mixer.music.play()  print('开始播放：%s -- %s秒'%(music[0] , str(music[1])))  return music

显示播放进度

# 播放进度显示def move(current_time,start_time,pause_duration_time,c_music):  if pause_end_time == 0 and pause_start_time != 0:    duration_time = round(pause_start_time - start_time - pause_duration_time)  else:    duration_time = round(current_time - start_time - pause_duration_time)  song_total_time = c_music[1]  speed = (end_x-begin_x)/song_total_time  current_x = begin_x + duration_time*speed  try:    screen.blit(dian,(current_x,148))    pygame.display.update()  except:    print(current_time)    print(start_time)    print(pause_duration_time)    exit()

快进快退功能

# 快进快退功能def kuaijin(jindu_x,c_music):  # 要跳转到的距离d_x  d_x = jindu_x - begin_x  song_total_time = c_music[1]  # 要跳转到的时间d_song_time  d_song_time = round(song_total_time*(d_x/560),1)  # 将歌曲快进到d_song_time  pygame.mixer.music.play(0,d_song_time)

画播放控件

# 画播放控件def draw_kongjian(is_sing,is_pause):  # 画进度条  # 画一条宽度为2的线，y高度为149，x从40到600,颜色为(0,100,100)  pygame.draw.line(screen, (0, 100, 100), (40, 149), (600, 149), 2)  # 画播放、暂停按钮  # 先画圆边框，半径20  pygame.draw.circle(screen, (0, 255, 255), (x + 80, 100), 20, 2)  # 画三角形，开始播放  pygame.draw.line(screen, (0, 255, 255), (x + 73.7, 107.5), (x + 73.7, 93), 2) # 竖线  # 如果正在播放且没有暂停  if is_sing and not is_pause:    # 隐藏三角形    pygame.draw.line(screen, (0, 89, 115), (x + 73.7, 107.5), (x + 87.3, 100), 2)    pygame.draw.line(screen, (0, 89, 115), (x + 73.7, 93), (x + 87.3, 100), 2)    # 显示第二条竖线    pygame.draw.line(screen,(0,255,255),(x+83.7,107.5),(x+83.7,93),2)  else:    # 隐藏第二条竖线    pygame.draw.line(screen, (0, 89, 115), (x + 83.7, 107.5), (x + 83.7, 93), 2)    # 显示三角形    pygame.draw.line(screen,(0,255,255),(x+73.7,107.5),(x+87.3,100),2)    pygame.draw.line(screen,(0,255,255),(x+73.7,93),(x+87.3,100),2)  # 画上一首按钮  pygame.draw.line(screen, (0, 255, 255), (x - 10, 110), (x - 10, 90), 2)  pygame.draw.line(screen, (0, 255, 255), (x - 10, 100), (x + 10, 115), 2)  pygame.draw.line(screen, (0, 255, 255), (x - 10, 100), (x + 10, 85), 2)  pygame.draw.line(screen, (0, 255, 255), (x + 10, 115), (x + 10, 85), 2)  # 画下一首按钮  pygame.draw.line(screen, (0, 255, 255), (x + 170, 110), (x + 170, 90), 2)  pygame.draw.line(screen, (0, 255, 255), (x + 170, 100), (x + 150, 115), 2)  pygame.draw.line(screen, (0, 255, 255), (x + 170, 100), (x + 150, 85), 2)  pygame.draw.line(screen, (0, 255, 255), (x + 150, 115), (x + 150, 85), 2)

主逻辑

1、画界面
2、如果没有在播放音乐，播放之
3、如果正在播放音乐，刷新播放进度
4、点击了上一首的处理
5、点击了暂停/播放的处理
6、点击了下一首的处理
7、快进/快退的处理
