How To Create Button To Control Background Sound.

I'm trying to add background music to my application. All I want is the sound should played on pressing the btnoptn Button and its text transitions into the 'music off'. The music

Solution 1:

This is a really simple example. I don't know how it works if you switch between Activities, i never really worked with the MediaPlayer class.

public class MainActivity extends Activity 
{
    private MediaPlayer mediaPlayer;
    private Button musicButton;
    private OnClickListener listener = new OnClickListener()
    {
        // a boolean value in the names Onclicklistener class. 
        // this will help us to know, if the music is playing or not.
        boolean isPlaying = false;

        @Override
        public void onClick(View arg0)
        {
            if(isPlaying)
            {
                mediaPlayer.pause(); //stop the music
                musicButton.setText("Start"); //change the buttons text
            }
            else
            {
                mediaPlayer.start(); //start the music
                musicButton.setText("Stop"); //change the text
            }
            //changing the boolean value
            isPlaying = !isPlaying;
        }
    };

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //Creating the mediaplayer with a desired soundtrack.
        mediaPlayer = MediaPlayer.create(this, R.raw.my_music);

        //Getting the Button reference from the xml
        musicButton = (Button) findViewById(R.id.music_button);

        //Setting the listener
        musicButton.setOnClickListener(listener);
    }
}
