안드로이드 ListFragment

Fragment 내에 ListView를 사용할 경우 보다 편리하게 구성할 수 있도록 제공되는 Fragment 이다.
ListView의 id가 @android:id/list로 설정되어 있을 경우 자동으로 ListView를 찾아 관리하게 된다.

 

package com.example.listfragment

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val subFragment = SubFragment()
        val tran = supportFragmentManager.beginTransaction()
        tran.replace(R.id.container1,subFragment)
        tran.commit()
    }
}

    }
