Canvas.scale - weekend data are zero, what's the problem?

[charlenef]

I use canvas.scale to optimise the playing field in my game, but faced a problem - canvas.scale(x,y) x and y = 0, so there's nothing on the screen, although the logic should be the point. How can this problem be addressed?

This is code:`public class Game extends Activity {

public static int heightDisplay;
public static int widthDisplay;
@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(new GamePanel(this));
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);

heightDisplay = displaymetrics.heightPixels;
widthDisplay = displaymetrics.widthPixels;

}

♪

public static final int WIDTH = 720;

public static final int HEIGHT = 1280;

@Override

public void draw(Canvas canvas)

{
if(canvas!=null) {
    final int savedState = canvas.save();
    canvas.scale(Game.widthDisplay/WIDTH, Game.heightDisplay/HEIGHT);
    bg.draw(canvas);
    canvas.restoreToCount(savedState);
}

}

The point is infinitely small, and it's not.
