Question

我正在使用pygame制作音乐播放器。但我无法理解如何在上一首歌曲结束后自动播放下一首歌曲。我的程序首先读取所选文件夹中的所有mp3文件。你能告诉我怎么做吗？

'module
Sub MyThing1
   UserForm1.Show
End Sub

Public Sub MyThing2
    '....rest of code
End Sub

'userform
Sub CommandButton1_Click()
   MyThing2
   Me.Hide
End Sub

我想在第一首歌自动完成后播放下一首歌。

Answer 1

文件可以在初始for循环中播放，你不需要将它们放在列表中然后播放它们。

关于播放mp3文件，您需要等待音乐播放才能退出。完成每个文件后，您可以以相同的方式开始播放下一个文件。

import tkinter.filedialog as filedialog
import os
import pygame

directory = filedialog.askdirectory()
print("Loding files from directory:", directory)
os.chdir(directory)
pygame.mixer.init()
for file in os.listdir(directory):
    if file.endswith('.mp3'):
        print("Playing file:", file)
        pygame.mixer.music.load(file)
        pygame.mixer.music.play()
        # Wait for the music to play before exiting 
        while pygame.mixer.music.get_busy():   
            pygame.time.Clock().tick(5)

Answer 2

您可以通过列表框选择目录中的任何歌曲，也可以播放。

如果您想一次播放所有歌曲，则可以添加另一个按钮，例如“ Play_all”，然后通过@saloua将代码分配给该按钮。

铃声文件夹放置在该“ audio_player.py”所在的文件夹内。

#audio_player.py
import os
import tkinter as tk
import pygame

def songs_list():
    files = [file for file in os.listdir('ringtone')]
    List = []
    for file in files:
        List.append(str(file))
        #print(file)
    #print(List)
    return List

def play(song_name):

    song_name_label['text'] = "Now Playing: " + song_name
    pygame.mixer.init()
    pygame.mixer.music.load("./ringtone/" + song_name)
    print("Playing:", song_name)
    pygame.mixer.music.play()

window = tk.Tk()
window .title("Any Name")
Height = 720
Width = 1080

# define size of window
canvas = tk.Canvas(window, bg='#3cd1fa',  height=Height, width=Width)
canvas.pack()

# play button **************************************************
play_button_frame = tk.Frame(window)
play_button_frame.place(relx=0.40, rely=0.88, relheight=0.1, relwidth=0.10)

play_button = tk.Button(play_button_frame, text="Play", font=25, fg='#d1d1d1', bg='black',
                        command=lambda: play(listbox.get(listbox.curselection()))  )
play_button.place(relx=0.01, rely=0.005, relheight=0.98, relwidth=0.49)


#list box (playlist) *************************************************
listbox_frame = tk.Frame(window, bg='green')
listbox_frame.place(relx=0.7, rely=0.2, relheight=0.6, relwidth=0.29)

listbox = tk.Listbox(listbox_frame, bg="white", selectmode='ACTIVE')
listbox.place(relx=0.01, rely=0.01, relheight=0.98, relwidth=0.98)

# song name *****************************************************************
song_name_frame = tk.Frame(window, bg='white')
song_name_frame.place(relx=0.20, rely=0.1, relheight=0.05, relwidth=0.60)
song_name_label = tk.Label(song_name_frame,font=("times now roman", 10))
song_name_label.place(relx=0.0, rely=0, relheight=1, relwidth=1)

# PLaylist, to display song in the list
playlist = songs_list()
for item in playlist:
    listbox.insert(tk.END, item)
# auto selecting 1st element of list box
listbox.selection_set( first = 0 )

window.mainloop()
