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

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);     }
