Question

I’ve read several topics to this but couldn’t find any good solution for my problem.

I’ve one Checkbox which is standard “checked” with state TRUE. I want know to stop my background music if I’m unchecking it – On the fly with no button. I know that there is something missing but I cant get it! Thanks for ur help!

I’m using this Code which has no errors but it doesn’t works correctly.

private CheckBox chkBoxMusic;
private MediaPlayer mp_music;
OnClickListener checkboxListener;


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

    setContentView(R.layout.sound);
    mp_music = MediaPlayer.create(this,R.raw.menusong);


    chkBoxMusic = (CheckBox) findViewById(R.id.checkBoxMusic);

    checkboxListener = new OnClickListener() {
         public void onClick(View v) {

            boolean checked = ((CheckBox) v).isChecked();

               if (!checked) {

                   mp_music.stop();
               }     
            }
    };

   chkBoxMusic.setOnClickListener(checkboxListener);

   }

}

Change you code as by using CompoundButton.OnCheckedChangeListener for checkbox:

chkBoxMusic.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
    {
        if ( !isChecked )
        {
            // perform logic
             mp_music.stop();
        }

    }
});
