Question

So i am using a list taken from an xml to load in mp3 files, you can start an mp3 file by clicking on it. Then i get the item clicked on like this:

var mp3Url:String = trackListList.selectedItem.@url;

I am pretty new to flex and i wondered if there was a way to select the next item based on this one.

Answer 1

A simple way would be like this:

var selIndex:int=trackList.dataProvider.getItemIndex(trackListList.selectedItem);
if(selIndex != -1) {
    selIndex++;
    nextMP3:String=trackList.dataProvider.getItemAt(selIndex).@url;
}

EDIT

var selIndex:int=trackList.selectedIndex;
if(selIndex != -1) {
    selIndex++;
    nextMP3:String=trackList.dataProvider.getItemAt(selIndex).@url;
}

selIndex is the index of the item selected in the data provider. -1 means nothing is selected
