当应用程序在后台运行时，音频会继续播放

Question

我有一个要在运行时播放的配乐作为主要主题：

App{
      ...............
   Audio{
        source: "../assets/Art Of Silence_V2.mp3"
        autoPlay: true
        loops : Audio.Infinite
   }
      .......
}

当应用程序在后台运行时，如何停止播放它？

Answer 1

假设您的应用程序包含在Window或ApplicationWindow组件中

Window{
      ...............
   Audio{
        readonly property bool forground : Window.visibility !== Window.Minimized &&
                                             Window.visibility !== Window.Hidden
        source: "../assets/Art Of Silence_V2.mp3"
        autoPlay: true
        loops : Audio.Infinite
        onForgroundChanged: { forground ? start() : stop() }
   }
      .......
}
