Question

I have created 4 tabs containing 4 images at the screen bottom in BlackBerry 9700. I want to know how do I resize these tabs dynamically to suit other blackberry screens. When I test the same code in 9800, I can see only 3 tabs and the fourth one goes out of visibility. I know resizing image dynamically for Background screens but how to do the same for tabs or image buttons?

Answer 1

you have to Resize your all Tabbar images depends on Device width using ResizeBitmap Class.

Ex: Bitmap tab = Bitmap.getBitmapResource("Your image path")
Bitmap tab1 = ResizeBitmap.resizeBitmap(tab, Display.getWidth()/4, tab.getHeight());

Resize all your four images like above. Than add four images to your Horizontalfield manager. Override sublayout() method and set its width & height.

Now you can see all tab perfect in all device.
