Hi,

I'm trying to add two radio button to my application. Is there an easy way to align two radio buttons  Horizontally on the screen without using the gridFieldManager?

Thank you.

My code

RadioButtonGroup rbg = newRadioButtonGroup();

add(new RadioButtonField("AAA",rbg,true,RadioButtonField.FIELD_VCENTER));

add(new RadioButtonField("BBB",rbg,false,RadioButtonField.FIELD_VCENTER));

did you try a HorizontalFieldManager?

Thanks Simon for the quick response. And yes, Actually I tried it but it didn't work . Maybe I need to build a specific gridManager for this situation. What do you think? And thank you again.

ok, i see, this is one of the fields that uses all width.
in 7.0 there is a style to supress that, but i guess it won't help earlier (you can try the numerical value, maybe it works!)
http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/ui/component/RadioButtonField....

second easiest solution would be to overwrite http://www.blackberry.com/developers/docs/7.1.0api/net/rim/device/api/ui/component/RadioButtonField.... to return your desired value.

if that does not work, or you find it too messy, create a custom layout, see http://supportforums.blackberry.com/t5/Java-Development/How-to-Extend-Manager/ta-p/446749

There is also a universal trick solving the problem.

You can restrict width of any built-in field (such as RadioButtonField) using the following simple layout override:

protected void layout(int maxWidth, int maxHeight) {
  super.layout(Math.min(maxWidth, myDesiredWidth), maxHeight);
}

Since fields created by RIM dutifully obey the limits passed to them (unlike many custom fields I see here in the forums ), this will restrict the width of your RadioButtonField and let the other one have some room in the same HorizontalFieldManager.

Good luck!

Hi Sultan

import net.rim.device.api.ui.component.RadioButtonField;
import net.rim.device.api.ui.component.RadioButtonGroup;
import net.rim.device.api.ui.container.HorizontalFieldManager;
import net.rim.device.api.ui.container.MainScreen;

public class pkj extends MainScreen{
public pkj() {
	// TODO Auto-generated constructor stub
 
	HorizontalFieldManager hfm = new HorizontalFieldManager();
	 
	RadioButtonGroup rbg = new RadioButtonGroup();
	hfm.add(new RadioButtonField("AAA",rbg,true,RadioButtonField.FIELD_VCENTER)
	{
	protected void layout(int maxWidth, int maxHeight) {
		  super.layout(Math.min(maxWidth, 60), maxHeight);
	}});
	
	hfm.add(new RadioButtonField("jha",rbg,true,RadioButtonField.FIELD_VCENTER)
	{
	protected void layout(int maxWidth, int maxHeight) {
		  super.layout(Math.min(maxWidth, 60), maxHeight);
	}});
	
	add(hfm);
}
}

 Thanks

Thank you so much Pankajac12 . The code worked for me. 

I just changed the maxwidth from 60 to 250.

Thanks again!
