在MediaPlayer中播放动态MP3文件

Question

I need to play local mp3 from the RAW folder. When i am calling it with direct name, like this way it works fine:

final MediaPlayer mP = MediaPlayer.create(MainActivity.this, R.raw.sound);
mP.start();

But i cannot figure it out how to play mp3 according to a variable containing the name of mp3, for example:

String filemane = "my.mp3";
final MediaPlayer mP = MediaPlayer.create(MainActivity.this, R.raw.filemane);
mP.start();

I understand this doesn't work since in the raw folder there is no file "filemane.mp3"

Please point me how to play "my.mp3"

使用Uri作为第二个参数。

MediaPlayer.create(MainActivity.this, Uri.fromFile(new File(path)));
