试图使复选框静音

Question

我对如何使复选框静音媒体播放器感到困惑。仅供参考我正在学习对话框，按钮，复选框。我刚刚学会了如何添加音乐，所以感谢任何帮助！

public class DialogBox extends Activity implements View.OnClickListener
{
    MediaPlayer mySound;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dialog_box);

        Button one = (Button)findViewById(R.id.btn);
        one.setOnClickListener(this);
        mySound = MediaPlayer.create(this,R.raw.mario);
    }
    @Override
    public void onClick(View v)
    {
        switch (v.getId())
        {
            case R.id.btn:
              mySound.start();
                break;
        }
}
