Auto Complete in J2ME

Hi.. I have a question regarding autocomplete in J2ME
I made an application that has more than 400 user input (it's road names),
So auto completing is a necessity in my case..
because it's very troublesome for user to find what the item they want;
they have to scroll down over 400 items..

But i can't find a reference regarding this feature anywhere...

So could anyone give me the general idea, of what i should do to create this feature?

I'm definitely sure it is possible in J2ME,
i've seen .jar applications that use this feature, such as Microsoft Encarta.

thanks.

There's no pre-packaged auto-complete even in the full J2SE. I don't know if there are any 3d-party solutions.

Basically, you'd rebuild the datamodel on the dropdown list every time someone typed (or removed) a character from the edit box. Generally, you don't start doing this until the edit text is several characters long and the tree of potential matches is manageably small.


Customer surveys are for companies who didn't pay proper attention to begin with.

So you required some kind of component like"Phone Book"
You can use the 3rd party component from J2ME Polish
the component name is "Filtered List"
It consist a combination of Text Field & List
