如何在此方案中传递res / raw / a01.wav文件

Question

我已将所有音频文件存储在res / raw中。现在我想将它提供给以下功能

 public void audioPlayer(raw raduio) {

        MediaPlayer mp5 = new MediaPlayer();

        try {


            mp5.setDataSource(); //how to feed raduio here ?
            mp5.prepare();
            mp5.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
        finally
        {
            mp5.reset();
        }
    }

怎么做？ 如何在方法中发送R.raw.a01作为参数？

Answer 1

使用以下代码[wavId - R.raw.a01]：

public void audioPlayer(raw raduio, int wavId) {

    MediaPlayer mp5 = new MediaPlayer();

    AssetFileDescriptor afd = mContext.getResources().openRawResourceFd(wavId);

    try {


        mp5.setDataSource(afd.getFileDescriptor()));
        mp5.prepare();
        mp5.start();
    } catch (Exception e) {
        e.printStackTrace();
    }
    finally
    {
        mp5.reset();
    }
}

你可以直接使用这个

MediaPlayer mPlayer = MediaPlayer.create( MainActivity.this,  R.raw.song1 );
mPlayer.setOnCompletionListener( new OnCompletionListener()
 {
   @Override
     public void onCompletion( MediaPlayer mp )
       {
          mp.release();
        }
  } );
  mPlayer.start();
