캐스트. 내가 android.app.AlertDialog을 사용한다면 충돌이 없지만 대화 상자가 재료 스타일이 아닙니다.

public class SearchFilterFragment extends DialogFragment { 

boolean isAscending; 
CheckBox checkbox;

    Bundle args = new Bundle(); 
    args.putInt(GiantBomb.ARRAY,array_id); 
    SearchFilterFragment fragment = new SearchFilterFragment(); 
    fragment.setArguments(args); 
    return fragment;

@Override

    super.onAttach(context); 
    try { 
     searchFilterInterface = (SearchFilterInterface) getTargetFragment(); 
    } catch (Exception e) { 
     Toaster.make(getContext(), "interface cast exception"); 
    } 



} 

@Override
