        seekbar.setMax((int) finalTime);
        seekbar.setClickable(false);
    }

    // play mp3 song
    public void play(View view) {
        mediaPlayer.start();
        timeElapsed = mediaPlayer.getCurrentPosition();
        seekbar.setProgress((int) timeElapsed);
        durationHandler.postDelayed(updateSeekBarTime, 100);
    }

    //handler to change seekBarTime

            //repeat yourself that again in 100 milliseconds
            durationHandler.postDelayed(this, 100);

i want to create the media player and play the selected the song on item click listener in media player , i am getting trouble in music player activity, how do i map the selected song name to song which i have to save in raw folder ??

when you click a particular song on the list, what you will get ?. song name or song url ?. if you have the song name, then get that song from your resource folder and play it. else if you have the song url, fetch it and play — Rince Thomas, Apr 08 '15 at 10:06
we dont know where your song is located. if its on device, search it with the name you get when you click the listfield. — Rince Thomas, Apr 08 '15 at 10:09
i have stored all the song list in raw folder, when i clicked on selected item list it will go to musicplayer activity , but on play button it gave null pointer exception — Priyanka....., Apr 08 '15 at 10:16
null pointer means, your media player didnt getting the selected song. — Rince Thomas, Apr 08 '15 at 10:21

I don't really understand, what you want, but try to do this:

public class MySongs {
public String name;
public int imageId;
public int songRawId;

public MySongs(String name, int imageId, int songRawId) {
    this.name = name;
    this.imageId = imageId;
    this.songRawId = songRawId;
}

}

Then you can use a List of your songs:

List<MySongs> songs = new ArrayList<MySongs>();

In the onCreate you can add all songs, which you want to have:

songs.add(new MySongs("name1", R.mipmap.ic_launcher, R.raw.song1));
songs.add(new MySongs("name2", R.mipmap.ic_launcher, R.raw.song2));
...

After that you can put this list in your listAdapter. In the OnItemClick just do MySongs selectedSong = songs.get(position);

Then you have all informations about the selected song. You can get them with selectedSong.name as example

i just want to play the selected song in media player which i have saved in raw folder — Priyanka....., Apr 08 '15 at 10:49

Please modify your code like below code

 list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                Intent i = new Intent(MarathiActivity.this,MusicPlayer.class);
                i.putExtra("SongName", web[position]);
                i.putExtra("Song", resID[position]);
                startActivity(i);
               // playSong(position);

            }
        });

MusicPlayer.class

    String m_songName;
    int m_songRes;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //set the layout of the Activity
        setContentView(R.layout.musicplayer);


        if(getIntent().getExtras()!= null)
        {
            m_songName = getIntent().getExtras().getString("SongName");
            m_songRes = getIntent().getExtras().getInt("Song");
        }

        //initialize views
        initializeViews();
    }

    public void initializeViews(){
        songName = (TextView) findViewById(R.id.songName);

        mediaPlayer = MediaPlayer.create(this,m_songRes);
        finalTime = mediaPlayer.getDuration();
        duration = (TextView) findViewById(R.id.songDuration);
        seekbar = (SeekBar) findViewById(R.id.seekBar);
        songName.setText(m_songName);

        seekbar.setMax((int) finalTime);
        seekbar.setClickable(false);
    }

choose song from list , navigate to media player on item click listener and play song with media player
