AlertDialogクラスキャスト例外

Question

私はandroid.support.v7.app.AlertDialogを使用する場合、私は

setviewコマンド（ビュー）AlertDialogの

メソッドを使用している場合、私はクラスのキャストオプションを取得します。 android.app.AlertDialogを使用しても、クラッシュはありませんが、ダイアログはマテリアルスタイルではありません。

public class SearchFilterFragment extends DialogFragment { 

boolean isAscending; 
CheckBox checkbox; 
View view; 
SearchFilterInterface searchFilterInterface = null; 
int which_one; 
int array_id; 


public interface SearchFilterInterface { 

    void onSelect(int which, boolean asc); 
} 


public static SearchFilterFragment newInstance(@ArrayRes int array_id) { 

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



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



} 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    array_id = getArguments().getInt(GiantBomb.ARRAY); 
    if (array_id==R.array.search_filter) { 
     which_one = SharedPreference.getFromSharedPreferences(GiantBomb.WHICH, 4, getContext()); 
     isAscending = SharedPreference.getFromSharedPreferences(GiantBomb.ASCENDING, true, getContext()); 
    }else { 
     which_one = SharedPreference.getFromSharedPreferences(GiantBomb.SORT_WHICH,1,getContext()); 
     isAscending = SharedPreference.getFromSharedPreferences(GiantBomb.SORT_ASCENDING,true,getContext()); 
    } 
} 


@NonNull 
@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 

    view = getActivity().getLayoutInflater().inflate(R.layout.search_option_layout,null); 

    checkbox = (CheckBox) view.findViewById(R.id.checkbox); 
    final int uncheck_color = ContextCompat.getColor(getContext(),R.color.black_white); 
    checkbox.setChecked(!isAscending); 
    if (!checkbox.isChecked()) { checkbox.setTextColor(uncheck_color) ;} 


    final AlertDialog dialog = new AlertDialog.Builder(getContext(),R.style.MyDialogTheme) 
      .setCancelable(true) 
      .setTitle("Sort result") 

      .setSingleChoiceItems(getResources().getStringArray(array_id), which_one, new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        which_one = which; 
       } 
      }) 
      //crashes here if i use v7 AlertDialog class 
      .setView(view) 

      }).create(); 
      dialog.setOnShowListener(new DialogInterface.OnShowListener() { 
       @Override 
       public void onShow(DialogInterface dialogInterface) { 
        dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(ContextCompat.getColor(getContext(),R.color.primary)); 
       } 
      }); 
      return dialog; 
} 

}
