Answer 1

add this code in onItemClickListener.

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();
            }
        });

Answer 2

try this for playing from raw ::

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

permission in manifest file ::

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

Update::

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();

Hope this may helps you.

          int position, long id) {

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

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

Answer 5

To play audio from the raw folder call this method. In my case my file name was notificaion.mp3 :

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

Here is the AudioPlayer class:

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()
    }

    }
}

Answer 6

Place your audio file in the res/raw folder and call it from the create method of MediaPlayer.

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

Eg:

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

Answer 7

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();
            }
        });
