i'm having difficult time figuring out how designing feels should straightforward layout collection view. heights of each cell equal. widths vary. inter-item spacing should always equal. distance between rows should equal. more items added, width of collection view increase "intelligently." let me give example. when insert new item, calculate movement of items rows (maybe first item of row 1 moves row 0, maybe first item of row 2 moves row 1. move , collection view grows wider. i feel should reasonably straightforward i'm struggling. have sample code help? have tried using uicollectionviewflowlayout? http://skeuo.com/uicollectionview-custom-layout-tutorial https://developer.apple.com/library/ios/documentation/uikit/reference/uicollectionviewflowlayout_class/

so have program need call method 2 items in object. thought, if have if user passes in nothing arguement... x.getitem(); it work , return 1 of 2 items. but if wanted specific item... x.getitem(0); or x.getitem(1); is possible in java? didn't want 0 random , 1 , 2 default...because confusing read later. it sounds want 2 methods: private a[] = new a[2]; public getitem() { return a[new random().nextint(1)]; } public getitem(int index) { return a[index]; } given parameters different 2 methods, can use same name (because compiler can distinguish 1 calling depending on actual parameters). if implement fakey optional parameter, single method more complex - have both ways of looking return value plus logic decide parameter had been omitted. 2 methods nice, clean solution.
