Graphics g ...
..set color...
g.fillRect( 0, 0, g.getWidth(), g.getHeight());

Hi,
Got the idea, thanks.
So, I guess we don't have clear screen command here, right ?

another question,
if I want to command g of graphic in other plaec ( run(), startApp(),
xxxxx() )...
I have to reference it ?

Example will helpful to me

Best regards,
Boki.

The only place you should use the Graphics is inside of paint().
Try:

In your Canvas.paint(Graphics) method, set the color in the Graphics
object and then call fillRect(0,0,getWidth(),getHeight()).

No. Once paint() exits, the Graphics object is invalid and should not be
used.
