Activity parchani qo'shish

Parchani ishlatish uchun uni MainActivity ga qo'shing. Buning uchun MainActivity interfeysini belgilaydigan activity_main.xml faylini o'zgartiraylik:

1 2 3 4 5 6 7

xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/fragment_container_view" android:layout_width="match_parent" android:layout_height="match_parent" android:name="com.example.fragmentapp.ContentFragment" />

FragmentContainerView elementi iborani qo'shish uchun ishlatiladi. Asosan, FragmentContainerView FrameLayout sinfini kengaytiradigan va fragmentlar bilan ishlash uchun maxsus mo'ljallangan View ob'ektini ifodalaydi. Aslida, bo'laklardan tashqari, u boshqa hech narsani o'z ichiga olmaydi.
Uning atributi android:name ishlatiladigan bo'lakning sinf nomini ko'rsatadi. Mening holimda, com.example.fragmentapp.ContentFragment paketini hisobga olgan holda, parcha sinfining to'liq malakali nomi.
MainActivity sinf kodi loyiha yaratilgandek qoladi:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

package com.example.fragmentapp; import androidx.appcompat.app.AppCompatActivity; import android.os.Bundle; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } }

Agar biz dasturni ishga tushiradigan bo'lsak, biz amalda biz bajaradigan interfeysni ko'ramiz, faqat bu holda interfeys fragmentda aniqlanadi:
Aytish joizki, Android Studio snippet qo'shish uchun tayyor shablonni taqdim etadi. Keling, aslida bu usuldan foydalanaylik.
