Problem with setFullScreenMode(true) in canvas

[mramin05]

Hi guys,
In my application I have two canvas class named as below.

  
  class Abc extends Canvas implements CommandListener{
            //constructor
            public Abc() {
            taskBack = new Command("Back",Command.BACK,1);
            // Some Image accessing code here
            addCommand(taskBack);
            setCommandListener(this);
            setFullScreenMode(true);
        }
  }
  class Xyz extends Canvas implements CommandListener{
            //constructor
            public Xyz() {
             taskBack = new Command("Back",Command.BACK,1);
            addCommand(taskBack);
            setCommandListener(this);
            setFullScreenMode(true);
     }
  }

These two classess are declared inside another class from which I control the display.
It displays the first canvas initially. and After a button press event the second canvas will be displayed.
Now The problem is: second canvas displayed in fullscreen but the first canvas is not displayed in full screen.
What is the problem with my code?
Is there any other idea to display a fullscreen canvas?
Please help me.
Thanks.

Hello

1. What phone are you using?

2. Put the

setFullScreenMode(true);

in the first line and see what happens.

Hi,
Thanks for your answer. I have tried with it and it gives the same result. I have tested in java wareless toolkit emulator.

Hi,
Like rdrincon suggested that is the way for setting the full screen ,mode.As rdrincon ask to you which is/are the targeted devices ..you did not explain..
Have you test it by putting on device..??

However you can try these points -
@ You can check that - instead of the getWidth() and getHeight you can just initialize the width and height of the screen size..
@ You can use the setFullScreenMode(true); after that above written lines..width and height..
Thanks,

Hi,
sorry for my less specification.
I have tested in nokia 60 series and sumsung U800
. I have another issue regarding this.
That is:
when I use

graphices.drawImage(image,getWidth(),getHeight(), Graphics.HCENTER|Graphics.VCENTER )

image just print in the top left conrner in 1/4 area of screen.
But when I use

graphices.drawImage(image,getWidth(),getHeight(), Graphics.LEFT|Graphics.TOP )

In Sumsung it prints in total screen but still show the command button in bottom which I add in the canvas.
And in nokia 60 width is ok. But the height is still about half of the screen.
But I want to show the image in full screen wish covers the total area including the area of the command button. and I am using the setFullScreenMode(true) in constructor of canvas class.
I hope this represent my problem.
Please help me.

u are taking into account the screen sizes and the image size right ?
As in if it only covers part of the screen it might be that the Image u are drawing is smaller than the screen sizes... J2ME wont strecht/fit the image for u !!!
In that case on one phone it might cover the whole screen (a lower resolution) whilst on another it will cover only part (higher resolution)...
to test it instead of drawing an image u could draw a solid rectangle, always using the TOP | LEFT and getWidth() getHeight() parameters...

Hi,
Well the anchor settings can vary from device to device...
If that image is coming in the half of the screen then you can just try the other anchor...

@ IS the size of the image is equal to the size of the size of screen..??
@ If yes then just set the full screen mode true..or just try to putting the screen width and height as the hard code values..
@ then just draw the image like
g.drawImage(0,0,0);

I am sure it can help you,
Thanks,
