代码实现

初始化

def __initialize(self):self.setWindowTitle("音乐播放器-Python工程狮")self.setWindowIcon(QIcon("icon.ico"))self.songs_list = []self.song_formats = ["mp3", "m4a", "flac", "wav", "ogg"]self.settingfilename = "setting.ini"self.player = QMediaPlayer()self.cur_path = os.path.abspath(os.path.dirname(__file__))self.cur_playing_song = ""self.is_switching = Falseself.is_pause = True# 界面元素# --播放时间self.label1 = QLabel("00:00")self.label1.setStyle(QStyleFactory.create("Fusion"))self.label2 = QLabel("00:00")self.label2.setStyle(QStyleFactory.create("Fusion"))# --滑动条self.slider = QSlider(Qt.Horizontal, self)self.slider.sliderMoved[int].connect(lambda: self.player.setPosition(self.slider.value()))self.slider.setStyle(QStyleFactory.create("Fusion"))# --播放按钮self.play_button = QPushButton("播放", self)self.play_button.clicked.connect(self.playMusic)self.play_button.setStyle(QStyleFactory.create("Fusion"))# --上一首按钮self.preview_button = QPushButton("上一首", self)self.preview_button.clicked.connect(self.previewMusic)self.preview_button.setStyle(QStyleFactory.create("Fusion"))# --下一首按钮self.next_button = QPushButton("下一首", self)self.next_button.clicked.connect(self.nextMusic)self.next_button.setStyle(QStyleFactory.create("Fusion"))# --打开文件夹按钮self.open_button = QPushButton("打开文件夹", self)self.open_button.setStyle(QStyleFactory.create("Fusion"))self.open_button.clicked.connect(self.openDir)# --显示音乐列表self.qlist = QListWidget()self.qlist.itemDoubleClicked.connect(self.doubleClicked)self.qlist.setStyle(QStyleFactory.create("windows"))# --如果有初始化setting, 导入settingself.loadSetting()# --播放模式self.cmb = QComboBox()self.cmb.setStyle(QStyleFactory.create("Fusion"))self.cmb.addItem("顺序播放")self.cmb.addItem("单曲循环")self.cmb.addItem("随机播放")# --计时器self.timer = QTimer(self)self.timer.start(1000)self.timer.timeout.connect(self.playByMode)# 界面布局self.grid = QGridLayout()self.setLayout(self.grid)self.grid.addWidget(self.qlist, 0, 0, 5, 10)self.grid.addWidget(self.label1, 0, 11, 1, 1)self.grid.addWidget(self.slider, 0, 12, 1, 1)self.grid.addWidget(self.label2, 0, 13, 1, 1)self.grid.addWidget(self.play_button, 0, 14, 1, 1)self.grid.addWidget(self.next_button, 1, 11, 1, 2)self.grid.addWidget(self.preview_button, 2, 11, 1, 2)self.grid.addWidget(self.cmb, 3, 11, 1, 2)self.grid.addWidget(self.open_button, 4, 11, 1, 2)

根据播放模式播放音乐

def playByMode(self):if (not self.is_pause) and (not self.is_switching):self.slider.setMinimum(0)self.slider.setMaximum(self.player.duration())self.slider.setValue(self.slider.value() + 1000)self.label1.setText(time.strftime("%M:%S", time.localtime(self.player.position()/1000)))self.label2.setText(time.strftime("%M:%S", time.localtime(self.player.duration()/1000)))# 顺序播放if (self.cmb.currentIndex() == 0) and (not self.is_pause) and (not self.is_switching):if self.qlist.count() == 0:returnif self.player.position() == self.player.duration():self.nextMusic()# 单曲循环elif (self.cmb.currentIndex() == 1) and (not self.is_pause) and (not self.is_switching):if self.qlist.count() == 0:returnif self.player.position() == self.player.duration():self.is_switching = Trueself.setCurPlaying()self.slider.setValue(0)self.playMusic()self.is_switching = False# 随机播放elif (self.cmb.currentIndex() == 2) and (not self.is_pause) and (not self.is_switching):if self.qlist.count() == 0:returnif self.player.position() == self.player.duration():self.is_switching = Trueself.qlist.setCurrentRow(random.randint(0, self.qlist.count()-1))self.setCurPlaying()self.slider.setValue(0)self.playMusic()self.is_switching = False

代码有点多~~
