Is there a way to find out which music is currently playing in the android Music player ? So I want to catch the title time and maybe the author of this music and show it with Textview. Is this possible ?
推荐答案
与此处的Android API一致: AudioManager 应该是您想要的
In concordance with the Android API here:AudioManager should be what you are looking for
您可以创建一个 AudioManager ，然后调用 isMusicActive 来检索布尔值(如果正在播放).
You can create an AudioManager and then call the isMusicActive to retrieve a boolean if it is playing.
然后，您可以使用 MediaPlayer API并调用 getTrackInfo 方法，该方法返回与轨道相关的信息的 Array .
You can then use the MediaPlayer API and call the getTrackInfo method which returns an Array of track-related information.
此外， MediaPlayer 有一个 isPlaying 方法，在这种情况下，它确实使AudioManager变得毫无用处.
Also, MediaPlayer has an isPlaying method which really makes AudioManager rather useless in this scenario.
[更新]
供以后观看此问题的读者使用；创建 MediaPlayer 对象并调用 getTrackInfo 方法时；它返回一个数组 TrackInfo [] ; TrackInfo [] 的API及其方法也可以找到此处.
For future viewers of this question; when you create a MediaPlayer object and call the getTrackInfo method; it returns an array TrackInfo[]; the API for TrackInfo[] and it's methods can also be found here.
