Android Audio SeekBar

I am trying to create something where a single sound file is played, and it can be paused and processed using the progress / search bar. I want the image to occupy most of the screen, and then the pause play button in the lower left and the panel to the right of the button. Everything works with a search program that is not related to audio. Modifying the barcode is probably a mess, because if you take it from a few that I saw on the Internet, but they mostly confuse me, because they are designed for applications with a music player, not for playing a single audio file.

Can someone please help me with the progress bar? Any other tips to improve my programming would be good too.

(I am very new to Android and programming to warn you)

This is my Java:

MediaPlayer mediaPlayer;
    Button buttonPlayPause;
    ImageView Image;
    SeekBar seekBar;

    private int stateMediaPlayer;
    private final int stateMP_NotStarter = 0;
    private final int stateMP_Playing = 1;
    private final int stateMP_Pausing = 2;
    int total;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.playerwere);

        Image = (ImageView) findViewById(R.id.pdfview);
        Image.setImageResource(R.drawable.wereim);

        seekBar = (SeekBar) findViewById(R.id.seekBar);

        buttonPlayPause = (Button) findViewById(R.id.playpause);

        buttonPlayPause.setOnClickListener(buttonPlayPauseOnClickListener);

        seekBar.setOnSeekBarChangeListener(seekBarOnSeekListener);

        initMediaPlayer();

        Thread currentThread = new Thread(this);
        currentThread.start();

    }

    private void initMediaPlayer() {
        mediaPlayer = new MediaPlayer();
        mediaPlayer = MediaPlayer.create(were.this, R.raw.were);
        stateMediaPlayer = stateMP_NotStarter;

        mediaPlayer.setOnPreparedListener(new OnPreparedListener() {

            @Override
            public void onPrepared(MediaPlayer arg0) {
                // TODO Auto-generated method stub
                total = mediaPlayer.getDuration();
            }

        });

        seekBar.setProgress(0);
        seekBar.setMax(total);
    }

    Button.OnClickListener buttonPlayPauseOnClickListener = new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            switch (stateMediaPlayer) {
            case stateMP_NotStarter:
                mediaPlayer.start();
    buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
                stateMediaPlayer = stateMP_Playing;
                break;
            case stateMP_Playing:
                mediaPlayer.pause();
    buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_play);
                stateMediaPlayer = stateMP_Pausing;
                break;
            case stateMP_Pausing:
                mediaPlayer.start();
    buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
                stateMediaPlayer = stateMP_Playing;
                break;
            }

        }
    };

    SeekBar.OnSeekBarChangeListener seekBarOnSeekListener = new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
            // TODO Auto-generated method stub

            if (fromUser) {
                mediaPlayer.seekTo(progress);
                seekBar.setProgress(progress);
            }

        }
    };

    @Override
    public void run() {
        // TODO Auto-generated method stub

        try {
            while (mediaPlayer != null) {
                int currentPosition = mediaPlayer.getCurrentPosition();
                Message msg = new Message();
                msg.what = currentPosition;
                threadHandler.sendMessage(msg);
            }
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    private Handler threadHandler = new Handler() {
        public void handleMessage(Message msg) {
            seekBar.setProgress(msg.what);
        }
    };

And this is what my Java was before I tried to use seekBar:

    MediaPlayer mediaPlayer;
    Button buttonPlayPause;
    ImageView Image;

    private int stateMediaPlayer;
    private final int stateMP_NotStarter = 0;
    private final int stateMP_Playing = 1;
    private final int stateMP_Pausing = 2;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.playerwere);

        Image = (ImageView) findViewById(R.id.pdfview);
        Image.setImageResource(R.drawable.wereim);

        buttonPlayPause = (Button) findViewById(R.id.playpause);

        buttonPlayPause.setOnClickListener(buttonPlayPauseOnClickListener);

        initMediaPlayer();

    }

    private void initMediaPlayer() {
        mediaPlayer = new MediaPlayer();
        mediaPlayer = MediaPlayer.create(were.this, R.raw.were);
        stateMediaPlayer = stateMP_NotStarter;
    }

    Button.OnClickListener buttonPlayPauseOnClickListener = new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            switch (stateMediaPlayer) {
            case stateMP_NotStarter:
                mediaPlayer.start();
    buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
                stateMediaPlayer = stateMP_Playing;
                break;
            case stateMP_Playing:
                mediaPlayer.pause();
    buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_play);
                stateMediaPlayer = stateMP_Pausing;
                break;
            case stateMP_Pausing:
                mediaPlayer.start();
    buttonPlayPause.setBackgroundResource(android.R.drawable.ic_media_pause);
                stateMediaPlayer = stateMP_Playing;
                break;
            }

        }
    };

This is my java after Vishal Vaja answer:

I think this may work for you.

Create one thread that will check the position of the song and move the search drum like this,

private Runnable moveSeekBarThread = new Runnable() {

    public void run() {
        if(mediaPlayer.isplaying){

        int mediaPos_new = mediaPlayer.getCurrentPosition();
        int mediaMax_new = mediaPlayer.getDuration();
        seekBar.setMax(mediaMax_new);
        seekBar.setProgress(mediaPos_new);

        handler.postDelayed(this, 100); //Looping the thread after 0.1 second
                                        // seconds
        }  
    }
};

And call this thread like this,

  mediaPos = mediaPlayer.getCurrentPosition();
  mediaMax = mediaPlayer.getDuration();

  seekBar.setMax(mediaMax); // Set the Maximum range of the
  seekBar.setProgress(mediaPos);// set current progress to song's

  handler.removeCallbacks(moveSeekBarThread);
  handler.postDelayed(moveSeekBarThread, 100);
