Dasturlash kodidan foydalanib, Fragmentni qanday amalga oshirish mumkin va qanday?

Ha, Androidda Fragmentni to'liq dasturlash orqali yaratish va boshqarish mumkin, XML-joylashtirishdan foydalanmasdan. Buning uchun:

1. Fragmentdan meros olgan sinf yaratish.
2. onCreateView metodini qayta yozish, unda asosiy View-ni dasturlash orqali yaratib, qaytarish.
3. Fragmentni Activity-ga FragmentManager yordamida kod bilan qo'shish.

Oddiy Fragmentni dasturlash orqali View bilan yaratish misoli:

class MyFragment : Fragment() {
    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?
    ): View? {
        val textView = TextView(requireContext())
        textView.text = "Dasturlash orqali yaratilgan Fragment"
        textView.gravity = Gravity.CENTER
        textView.textSize = 20f
        return textView
    }
}

Fragmentni Activity-ga dasturlash orqali qo'shish:

supportFragmentManager.beginTransaction()
    .replace(R.id.fragment_container, MyFragment())
    .commit()

Shunday qilib, butun UI va fragmentning mantiqi kod yordamida yaratilishi va boshqarilishi mumkin, XMLsiz.
