[PLEASE HELP]WHY CAN NOT I SEE THE GIF On The CANVAS???

Question

加载不会错的至少ＩＭＧ［Ｉ］不为空if(img[i] != null)
{
//String can be draw
g2.drawString(strText[i],5,5 + i * 18);
g2.setColor(Color.white);
//but gif file can be draw?
g2.drawImage(img[i],5,5 + i * 18,16,16,this);
}
至于什么错，我还没看出来

Answer 1

public void paint(Graphics g)
{
if(bufferImg == null)
{
createBuffer();
repaint();
}
else
g.drawImage(bufferImg,0,0,this);
}修改如下：
public void paint(Graphics g)
{
createBuffer();
g.drawImage(bufferImg,0,0,this);
}

Answer 2

我弄出来了,谢谢啦.
public void paint(Graphics g)
{
if(bufferImg != null)
g.drawImage(bufferImg,0,0,this);
}
public void update(Graphics g)
{
createBuffer();
g.drawImage(bufferImg,0,0,this);
}

我是这样做的：                  for (int i = 0; i < vURL.size(); i++)
                  {
                        img[i] = Toolkit.getDefaultToolkit().getImage(IconCanvas.class.getResource( (String)vURL.get(i)));
                        MediaTracker tracker = new MediaTracker(this);
                        tracker.addImage(img[i], 1);
                        try
                        {
                              tracker.waitForID(1);
                        }
                        catch (InterruptedException e)
                        {
                              e.printStackTrace();
                        }
                  }我用你的方法显示来出来
