When you have programmed your midlet for perfect fitting of your test device screen resolution, for instance 176x208, and now you want to make the application adapt automatically for other screen sizes, you can do that with out making much of a change in the Midlet.

First of all you need to declare two public variables accessible through out the midlet. At the load of the midlet, get the getWidth and getHeight values of Display object.

scrnW=getWidth();
scrnH=getHeight();
hfactor=scrnW/176f;
vfactor=scrnH/208f;

Now multiply these factors with each hard coded values you have set for vertical and horizontal components of your drawing code. Make sure that you add the “f” after your constants for floating point accuracy

Thanks. But some devices report the width and height improperly and cause my application to go out of screen. Is there any way to solve this problem ?

hi there,
there is a class provided in motorola sdk com.motorola.extensions.ScalableJPGImage
in which you can scale jpg images to fit correctly in you application needs..
not only for jpg images but for png too...


ScalableJPGImage sImage = ScalableJPGImage.createImage(
"/test.jpg", 10, 10);

where test.jpg is the image in resource folder..

in this example i have set the image size 10 for width and height respectively
it can modified to screen size using GETheight() and getwidth() property
