我在res/raw文件夹中有多个音频文件。我显示ListView包含音频文件的名称。当用户选择进入ListView. 我用过setDataSource(path)，但是玩的时候显示错误。如何直接从该文件夹播放音频文件？或者有没有其他方法？

在 onItemClickListener 中添加此代码。

listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {                 
                TextView txtView=(TextView)view.findViewById(R.id.txt_view);
                String fname=txtView.getText().toString().toLowerCase();

                                int resID=getResources().getIdentifier(fname, "raw", getPackageName());

                              MediaPlayer mediaPlayer=MediaPlayer.create(this,resID);
                    mediaPlayer.start();
            }
        });

试试这个从原始播放:: 

MediaPlayer mPlayer2;
mPlayer2= MediaPlayer.create(this, R.raw.bg_music_wav);
        mPlayer2.start();

清单文件中的权限::

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

更新：：

public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {     
  MediaPlayer mPlayer2;
if(position==1)
{
    mPlayer2= MediaPlayer.create(this, R.raw.song1);
            mPlayer2.start();
}else it() .....
}

mVideoView = (VideoView) findViewById(R.id.Video_FrontPage);
uri = Uri.parse("android.resource://com.urPackageName/" + R.raw.welcom_video);
mVideoView.setVideoURI(uri);
mVideoView.setMediaController(new MediaController(this));
mVideoView.requestFocus();
mVideoView.start();

      public void onItemClick(AdapterView<?> parent, View view,
          int position, long id) {

          // selected item 
          String product = ((TextView) view).getText().toString();

          int [] resID= {R.raw.sound1,R.raw.sound2,R.raw.sound3};

          mediaPlayer.start();
          // sending data to new activity


      }
    });

将您的音频文件放在 res/raw 文件夹中，然后从 MediaPlayer 的 create 方法中调用它。

MediaPlayer.create(this, R.raw.audio_file_name).start();

例如：

MediaPlayer.create(this, R.raw.sample).start();

要播放原始文件夹中的音频，请调用此方法。在我的情况下，我的文件名是notificaion.mp3：

AudioPlayer().playAudio(mContext, "notificaion")

这是 AudioPlayer 类：

class AudioPlayer {
private var mMediaPlayer: MediaPlayer = MediaPlayer()

private fun stopAudio() {
   try {
       mMediaPlayer.release()
   }catch (ex: Exception){
       ex.printStackTrace()
   }

}

fun playAudio(mContext: Context, fileName: String) {
    try {
        stopAudio()
        mMediaPlayer = MediaPlayer.create(mContext, mContext.resources.getIdentifier(fileName, "raw", mContext.packageName))
        mMediaPlayer.setOnCompletionListener {  stopAudio() }
        mMediaPlayer.start()
    }catch (ex: Exception){
        ex.printStackTrace()
    }

    }
}

var mediaPlayer = MediaPlayer.create(context, R.raw.sound_file_1)
mediaPlayer.start() // no need to call prepare(); create() does that for you

listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View view, int position,long id) {                 
                TextView txtView=(TextView)view.findViewById(R.id.txt_view);
                String fname=txtView.getText().toString().toLowerCase();

                                int resID=getResources().getIdentifier(fname, "raw", getPackageName());

                              MediaPlayer mediaPlayer=MediaPlayer.create(this,resID);
                    mediaPlayer.start();
            }
        });

add this code in onItemClickListener and one more information is you can't play any file other than mp3 and the mp3 file must be the original extension as file.
