Welcome to the forums.


I recommend that you use the EvenlySpacedHorizontalFieldmanager or HorizontalButtonFieldSet from here:

Re: Two buttons



You can get this by overridng sublayout of the title manager and no need to take seperate manager for each and every button.


Try like this,

HorizontalFieldManager titleHFM = new HorizontalFieldManager(HorizontalFieldManager.FIELD_HCENTER)
            protected void sublayout(int maxWidth, int maxHeight)
                setPositionChild(getField(0), 0, 0);
                layoutChild(getField(0), getField(0).getPreferredWidth(),getField(0).getPreferredHeight());
                setPositionChild(getField(1), Display.getWidth() - getField(1).getPreferredWidth(), 0);
                layoutChild(getField(1), getField(1).getPreferredWidth(),getField(1).getPreferredHeight());
                setExtent(maxWidth, maxHeight);

titleHFM.add(new ButtonField("Left"));
titleHFM.addnew ButtonField("Right");

Re: Two buttons

I recommend you look at the code supplied in the KB article I previously pointed you at and use that code.  The samples supplied are well written and demonstrate best practice. 


Unfortunately the example given above by lakshman9687 has a number of issues.  For example, the last line

setExtent(maxWidth, maxHeight);

will grab the maximum amount of space for the Manager, in fact it only needs enough height for the two buttons.
