pygame編寫音樂播放器的實現(xiàn)代碼示例
1、準備工作
ide:pycharm
python:3.7
三方包:pygame、pyinstaller、mutagen
幾首mp3格式的歌
2、開始
2.1 設計說明
1、包含 上一首、下一首、暫停/播放、快進/快退、顯示當前播放的歌曲名稱、顯示播放進度條
2、使用pygame.mixer
3、隨機播放磁盤某個目錄及其子目錄下的mp3文件
4、上一首、下一首用隨機選擇choice(list) 實現(xiàn)
5、進度條用按照一定速度移動進度圖片來實現(xiàn),過程中處理暫停、快進
6、歌曲快進播放用pygame.mixer.music.play(0,d_song_time) 實現(xiàn)
7、暫停用pygame.mixer.music.pause() 實現(xiàn)
8、播放用pygame.mixer.music.unpause() 實現(xiàn)
9、用mutagen.mp3來獲取mp3信息
2.2 代碼邏輯
收集某個目錄下的所有mp3
# 收集某個目錄及子目錄下的MP3格式的文件
# 返回歌曲路徑、歌曲時長

主邏輯
1、畫界面
2、如果沒有在播放音樂,播放之
3、如果正在播放音樂,刷新播放進度
4、點擊了上一首的處理
5、點擊了暫停/播放的處理
6、點擊了下一首的處理
7、快進/快退的處理
