            super(context);
            ourHolder=getHolder();

        }
        @Override

            while(isRunning)

                {
                    canvas.drawBitmap(bitmap[timer], 10,20,null);
                }
                ourHolder.unlockCanvasAndPost(canvas);
            }   
        }

放

  try{
  Thread.sleep(1000);    
  canvas.drawBitmap(bitmap[timer], 10,20,null);
  }catch(InterruptedException e){
}

它符合你的答案吗？
