BaseViewBindingDialogFragment

A base DialogFragment class for DialogFragments that use ViewBinding.
Extends ParentBindingViewDialogFragment to provide common binding functionality.

ViewBinding을 사용하는 DialogFragment를 위한 기본 DialogFragment 클래스입니다.
ParentBindingViewDialogFragment를 상속받아 공통 바인딩 기능을 제공합니다.

Why this class exists / 이 클래스가 필요한 이유:

  • Android's ViewBinding requires manual inflate() calls for each DialogFragment.

  • This class eliminates boilerplate by accepting an inflate function reference and automatically setting up the binding.

  • Provides type-safe view access without findViewById() or synthetic imports.

  • Android의 ViewBinding은 각 DialogFragment마다 수동으로 inflate() 호출이 필요합니다.

  • 이 클래스는 inflate 함수 참조를 받아 자동으로 바인딩을 설정하여 보일러플레이트를 제거합니다.

  • findViewById()나 synthetic import 없이 타입 안전한 뷰 접근을 제공합니다.

Design decisions / 설계 결정 이유:

  • Uses constructor parameter for inflate function reference to enable compile-time type safety.

  • Implements final createBinding() to prevent subclasses from breaking the binding initialization contract.

  • Properly handles isAttachToParent parameter for flexible view inflation.

  • In DialogFragment, keeping the default false for isAttachToParent is recommended unless there is a verified special case.

  • 컴파일 타임 타입 안전성을 위해 생성자 파라미터로 inflate 함수 참조를 사용합니다.

  • final createBinding()을 구현하여 하위 클래스가 바인딩 초기화 계약을 깨는 것을 방지합니다.

  • 유연한 뷰 인플레이션을 위해 isAttachToParent 파라미터를 적절히 처리합니다.

  • DialogFragment에서는 특별한 경우가 아니라면 isAttachToParent의 기본값 false 사용을 권장합니다.

Usage / 사용법:

  1. Extend this class with your DialogFragment and pass the ViewBinding inflate function reference.

  2. Access views through the getBinding() method in onViewCreated() or later lifecycle methods.

  3. Override onViewCreated(binding, savedInstanceState) to perform initial view setup after binding is ready.

  4. DialogFragment에서 이 클래스를 상속받고 ViewBinding inflate 함수 참조를 전달하세요.

  5. onViewCreated() 또는 이후 생명주기 메서드에서 getBinding() 메서드를 통해 뷰에 접근하세요.

  6. 바인딩이 준비된 후 초기 뷰 설정을 수행하려면 onViewCreated(binding, savedInstanceState)를 오버라이드하세요.

Usage example:

class HomeDialogFragment : BaseViewBindingDialogFragment<DialogFragmentHomeBinding>(
DialogFragmentHomeBinding::inflate
) {
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
// Binding is already initialized and views are ready
getBinding().textView.text = "Hello"
}
}

Parameters

BINDING

The type of ViewBinding class.

ViewBinding 클래스의 타입.

inflate

The inflate function reference for the ViewBinding class (e.g., DialogFragmentHomeBinding::inflate).

ViewBinding 클래스의 inflate 함수 참조 (예: DialogFragmentHomeBinding::inflate).

isAttachToParent

Whether to attach the inflated view to the parent container.

인플레이션된 뷰를 부모 컨테이너에 첨부할지 여부.
DialogFragment에서는 특별한 경우가 아니라면 기본값 false 사용을 권장합니다.

Functions

Link copied to clipboard
fun consumeOrphanedDeniedResults(): List<OrphanedDeniedRequestResult>

Returns and clears denied results that lost their callbacks after process restore.
Call this in onCreate to handle results from requests that were interrupted by process kill.

프로세스 복원 후 콜백을 잃은 거부 결과를 반환하고 비웁니다.
프로세스 킬로 중단된 요청의 결과를 처리하려면 onCreate에서 호출하세요.

open fun onBindingCreated(binding: BINDING, savedInstanceState: Bundle?)

Called immediately after the binding object is created, inside onCreateView().
Use only for binding variable assignment (e.g. binding.vm = vm).
Do NOT access viewLifecycleOwner, start collectors, or call lifecycle-aware APIs here — viewLifecycleOwner is not yet available at this point.

onCreateView() 내부에서 바인딩 객체가 생성된 직후 호출됩니다.
바인딩 변수 할당(예: binding.vm = vm)에만 사용하세요.
viewLifecycleOwner 접근, collector 시작, lifecycle-aware API 호출은 금지입니다 — 이 시점에서는 viewLifecycleOwner를 아직 사용할 수 없습니다.
