Multiple buttons with same width equal to widest button

I have multiple ButtonFields in a VerticalFieldManager. By d开发者_开发问答efault the width of each button depends on the text it contains.

I would like all the buttons to be of the same width - equal to the width of the widest button.

Take a look at the BlackBerry Developers Knowledge Base:

You are probably looking for the VerticalButtonFieldSet!

Step 1 - Extend the VerticalFieldManager class, and make the constructor take in a bunch of Strings that you want to put end each button.

Step 2 - Find the longest of String out of the Strings passed into the manager.

Step 3 - create the button for the longest string

Step 4 - create all other buttons, and set their width to the same as the 1st (see setExtent)

Step 5 - add the buttons to the manager in the order you want them to appear

Have you tried using the Field.USE_ALL_WIDTH style flag?

Try ButtonField buttonField = new ButtonField("ButtonText", Field.USE_ALL_WIDTH);

and that should use the full width.

If that doesn't work, try extending ButtonField, overriding layout and calling setExtent(width, height) with the width and height that you want.
