java - What is right way to work with tableview? -

for time have been trying tableview work kind of spreadsheet updated background thread , when cell updated, few seconds higlights ( changes style ) , goes original style. know, can't store , set styles directly in table cell , need kind of backing class, hold data. tableview "reusing" of cells (using same cells different data) acts weird. when cells fits on screen works flawlessly me, once place around 100 cells , becomes scrollable starts being buggy, styles ( or setted graphic) disappears , after scrolling appears, if disable top cells of view, other cells after scrolling disabled , on. there right way this?

what need

background data thread ---updates--> tableview thread --after few seconds removes style--> tableview 

as have now, have model class holds data, style , reference table cell should ( disabled ordering, should ok ) , background thread updates data in model class, , model class changes style on referenced cell , register in "style remover" thread, after while removes style.

i think posting actual code won't useful, because once i've discovered cells being reused code has become complicated , little bit unreadable want redo right way.

peformance not important me, there wont more 100 cells, highlighting , having buttons in tableview must work flawlessly.

this how app looks - idea of need.

edit: here link another question related this.

the collaborators:

• on data side, (view) model has recentlychanged property, that's updated whenever value changed
• on view side, custom cell listens recentlychanged property , updates style appropriate

the tricky part clean cell state when re-used or not-used: method that's (hopefully!) called cell.updateindex(int newindex), that's place un-/register listener.

below runnable (though crude ;) example
