Waɗanda suke Fragments kuma suna bambanta da Activities ta yaya?

Question

Accepted Answer

A **Fragment** shine wani yanki mai amfani na UI wanda yake zaune a cikin Activity — wani component na UI mai tsari, mai kansa-sarau tare da dalilinsa sarari. Fragments suna ba da damar UI masu ƙarfi, na gida, kuma suna da mahimmanci ga gida moderne na single-Activity.

## Abin da Fragment yake

```text
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.
```

## Fragments vs Activities

```text
ACTIVITY → a top-level screen/entry point; heavier; managed by the OS; declared in manifest
FRAGMENT → a UI portion WITHIN an activity; lighter, reusable, modular; managed by the
  activity's FragmentManager; NOT declared in the manifest
→ Fragments are more flexible/reusable; activities are the containers/entry points.
```

## Me ya sa fragments suna da amfani

```text
✓ REUSABILITY — use the same fragment in different activities/contexts
✓ FLEXIBLE/RESPONSIVE layouts — e.g. master-detail: two fragments side-by-side on a
  tablet, separate screens on a phone (same fragments, different arrangement)
✓ MODULARITY — break a complex screen into manageable, self-contained pieces
✓ Modern NAVIGATION — single-activity architecture: ONE activity, many fragments as
  "screens" (Navigation Component manages fragment navigation) — the recommended pattern
```

## Me ya sa yana da mahimmanci

Tubali Fragments kuma suna bambanta da Activities yana da mahimmanci domin **fragments suna da mahimmanci ga gida na UI na Android na zamani**, saboda haka yana da mahimmancin ilimi don Android development.

A **Fragment** (wani yanki na UI mai amfani, mai tsari, da ke gida a cikin Activity, tare da dalilinsa sarari) shine wata muhimmi gida, kuma tubali **bambanci daga Activities** — activities shine gabaɗaya alluran nuni/buɗin shiga (masu nauyi, da OS ke sarrafa, da aka ayyana a manifest) yayin da fragments sune masu haɓaka, yankuna UI mai amfani a cikin activities (da FragmentManager ke sarrafa) — ya bayyana ayyakansu daban-daban.

Tubali **me ya sa fragments suna da amfani** shine muhimmin ilimin aiki: **amfani daga jiya** (amfani da iri daya na fragment a garin daban-daban), **ɓatɓatuwa/amsawa na tsarukan** (tsarin master-detail mai shahara — fragments biyu daban-daban a gefe cikin tablet amma screens daban a waje, suna daidaita ga girman allon tare da iri daya na fragments), **tsarukan** (ɓatɓatuwa tubuli-masu-ɗabi'u a yankuna samarwa), kuma mahimman **gida-Activity-gida na zamani** (tsarin da an tabaita wanda Activity guda daya ke watse fragments da yawa azaman "screens," tare da Navigation Component ke sarrafa wariya tsakanin su).

Zanin-Activity-gida-gida, -fragment-sarrafa na zamani shine tsari na zamani, da aka ba da shawarar saba da kudi ga apps na Android, da sa tubali Fragments mahimmanci don gida na apps hanya ta zamani.

Tubali fragments kuma dalilinsu sarari (bambaci daga amma danganta da activity) mai mahimmanci don sarrafa su daidai.

Tunda fragments suna da mahimmanci ga gida na UI na Android na zamani (amfani daga jiya, tsarukan amsa, kuma musamman tsarin wariya-sarari/fragment-sarrafa da aka ba da shawarar saba), kuma tubali su kuma bambantinsu daga activities yana da mahimmanci don gida na apps hanya ta zamani, tubali Fragments ilimi mahimman, da aiki-sani na Android — mahimmi gida na gida na UI na Android na zamani, mahimmanci don gida na apps masu nufin amfani, na kara-murya, da masu tsari suke amfani da tsarin da aka ba da shawarar saba-Activity, kuma a rayuka da ake sani da su a gida na Android development.
