Fragment is comhréir in-athúsáidte de UI a bhíonn ina chónaí laistigh de Activity — comhpháirt UI modúlach, féin-bhainteach agus dá cuid saolré féin aici. Cumasaíonn Fragments UIs solúbtha, in-athúsáidte agus tá siad lárnach do ailtireachtaí nua-aimseartha aon-Activity.
Cad is Fragment ann
A FRAGMENT = a reusable, modular piece of UI hosted inside an Activity:
→ has its OWN lifecycle (tied to but distinct from the host activity's)
→ multiple fragments can be combined in one activity; reused across activities
→ represents a portion of the screen (or a whole screen's content)
→ Think: an activity can host one or more fragments that make up its UI.
