        setContentView(R.layout.main);
        mp = MediaPlayer.create(this, R.raw.test);
        mp.start();
        mp.setLooping(true);
        addListenerOnButton();
    }

    public void addListenerOnButton()
    {
        boy1 = (Button) findViewById(R.id.boy1);
        boy1.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View arg0) {
                mp.stop();
                startActivity(new Intent(Main.this, Boy1.class));
            }
        });     
    }

    @Override
    protected void onPause() {
        super.onPause();
        mp.stop();
    }

    @Override 
    public void onBackPressed() {
        super.onBackPressed();
        mp.stop();
        finish();
    } 

    @Override 
    public void onResume()
    {
        super.onResume();
    }

    @Override
    protected void onStop() {
        super.onStop();
        mp.stop();
    }

}  

You can do this using mediaPlayer.pause();
