应用程序的背景音乐应该有自己的主题吗? [英] Should an App's background music have a thread of it's own?

问题描述

我正在尝试构建一个应用程序，每当调用 onCreate() 时都会播放一段音乐，我希望在整个应用程序(即跨活动)中播放这些音乐.到目前为止，我所做的是在 OnCreate() 中创建一个线程，并将其命名为 backgroundMusic，在其中我从原始文件夹中的音乐作品创建了一个 MediaPlayer 对象.考虑到音乐本身只运行一分钟左右，并且平均花费在应用程序上的时间更多，我做了一个循环，只要应用程序正在运行，就会检查音乐是否正在播放，如果没有，则调用 start();

I'm trying to build an app where a piece of Music is played whenever the onCreate() is called, and I want for this music to be played throughout the whole app ie across Activities. what I've done so far is to create a Thread,within the OnCreate(), and I called it backgroundMusic, inside of it I created A MediaPlayer Object from a music piece in my Raw Folder. given that the music itself only runs for a minute or so and the average time spent on the app is more, I made a while Loop that as long as the app is running checks if the music is playing, if not then call start();

backgroundMusic = new Thread(new Runnable() {
    @Override
    public void run() {
        while ( appIsRunning ){

            if( ! music.isPlaying () ){
                music.start();
            }
        }
    }
});backgroundMusic.start();

代码运行得很好，但是我确实注意到一些滞后，尤其是在加载其他一些线程和图像之后.我想问的是，这是播放背景音乐的合适方式吗?有没有更好更有效的方法来做到这一点?另外，如何在应用关闭时让音乐停止?

the code runs just fine, however I did notice some Lag especially later when some other Threads and Images gets loaded.what I want to ask, is this an appropriate way to play background Music? is there a better more efficient way of doing that? also, how do I make the music stop as the app closes?

推荐答案

这是播放背景音乐的合适方式吗?

is this an appropriate way to play background Music?

不，您需要在服务上声明音乐.一项服务:

No, you need to declare music on a service. A service :

• 将独立于活动生命周期，因此当活动关闭时音乐将继续播放

• Will be independent of activity LifeCycle hence music will keep playing when Activity is closed

可以在需要时暂停，如来电

can be paused when needed like incoming call
