Mavjud Activity ga Fragmentni qanday qo'shish mumkin?

Androidda mavjud Activity ga Fragment qo'shish uchun odatda quyidagi bosqichlar bajariladi:

1. Activityning maketida (XML) fragment uchun konteyner yaratiladi, masalan, noyob ID bilan FrameLayout:

<FrameLayout
    android:id="@+id/fragment_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

2. Activity kodida, kerakli Fragment nusxasi yaratiladi va FragmentManager va FragmentTransaction yordamida konteynerga qo'shiladi:

FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
MyFragment fragment = new MyFragment();
transaction.add(R.id/fragment_container, fragment);
transaction.commit();

3. Agar kerak bo'lsa, replace() yoki remove() metodlari yordamida fragmentni o'zgartirish yoki olib tashlash mumkin.

Shu tarzda, fragment dinamik ravishda faoliyat ichidagi konteynerga qo'shiladi, bu esa UI va komponentlarning hayot aylanishini moslashuvchan boshqarishga imkon beradi.
