Fragment- ListFragment & DialogFragment

ListFragment

Frag 내에 ListView를 사용할 경우 편리
id가 @android:id/list (안드로이드 OS가 알고있는 내용)

Main Activity


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

class MainActivity : AppCompatActivity() {

var list_fragment = TestListFragment()

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

    var tran = supportFragmentManager.beginTransaction()
    tran.replace(R.id.container, list_fragment)
    tran.commit()
}

}
