정확히 어디가 문제인지 모르겠습니다..

책에 있는 예제를 그대로 작성하였는데 계속해서 에러가 나서...


public class ImageEx extends Activity{
   
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        setContentView(new SoundEx(this));
      }
}

이 액티비이 측 호출하려는 부분이고 실제 코드는 밑 입니다..


public class SoundEx extends View{
   
    MediaPlayer M_BackGround;
    MediaPlayer M_Effect_1;
    MediaPlayer M_Effect_2;
   
    public SoundEx(Context context){
        super(context);
       
        M_BackGround = MediaPlayer.create(context, R.raw.background);
        M_Effect_1 = MediaPlayer.create(context, R.raw.effect1);
        M_Effect_2 = MediaPlayer.create(context, R.raw.effect2);
       
        M_BackGround.start();
        //쓰레드와 같이 스타트, 스탑으로 함.
        setFocusable(true);
        //따로 리턴값을 받아 재생하는 것이 아닌 이곳에 포커스를 맞추어 그대로 실행함.
    }
   
    protected void onDraw(Canvas canvas)
    {
        Paint P = new Paint();
        P.setTextSize(20);
        P.setColor(Color.WHITE);
        String Str;
       
        if(M_BackGround.isPlaying())
        {
            Str = "재생 중";
        }
       
        else
        {
            Str = "일시 정지";
        }
       
        canvas.drawText("현재 음악의 상태는 " + Str , 0, 20, P);
       
    }
   
   
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
       
        if(keyCode == KeyEvent.KEYCODE_DPAD_LEFT)
        {
            M_Effect_1.start();
        }
       
        if(keyCode == KeyEvent.KEYCODE_DPAD_RIGHT)
        {
            M_Effect_2.start();
        }
       
        if(keyCode == KeyEvent.KEYCODE_SPACE)
        {
            if(M_BackGround.isPlaying())
            {
                M_BackGround.pause();
               
            }
            else
            {
                M_BackGround.start();
               
            }
            invalidate();
        }
        return super.onKeyDown(keyCode, event);
    }

}
