How to call 2 Fragment Dialog from one activity?
from the activity I declare and call:

// для DialogFragment
 DialogFragment dlgstart;
 DialogFragment dlgfinish;
// инициализируем fragment
dlgstart = new Startdlg();
dlgfinish = new Finishdlg();

//вызываю
dlgstart.show(getFragmentManager(), "dlgstart");
dlgfinish.show(getFragmentManager(), "dlgfinish");

class for fragment

public class Startdlg extends DialogFragment implements OnClickListener {
  
  final String LOG = "myLogs";
  Toast toast;
  int level;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
      //getDialog().setTitle("Title!"); 
      // ставим прозрачный цвет
      getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
      
      // убираем title из окна
      getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE); 
      
      View v = inflater.inflate(R.layout.startdlg, null);
      v.findViewById(R.id.butlevel1).setOnClickListener(this);
      v.findViewById(R.id.butlevel2).setOnClickListener(this);
      v.findViewById(R.id.butlevel3).setOnClickListener(this);
      return v;
    }
    
    public void onDismiss(DialogInterface dialog) {
        super.onDismiss(dialog);
        Log.d(LOG, "Dialog 1: onDismiss");
      }

      public void onCancel(DialogInterface dialog) {
        super.onCancel(dialog);
        Log.d(LOG, "Dialog 1: onCancel");
        Toast.makeText(getActivity(),getActivity().getString(R.string.alert_nolevelvub), Toast.LENGTH_SHORT).show();
        getActivity().finish();
      }

      public static interface OnCompleteListener {
            public abstract void onComplete(int time);
        }

        private OnCompleteListener mListener;

public void onAttach(Activity activity) {
    try {
        this.mListener = (OnCompleteListener)activity;
    }
    catch (final ClassCastException e) {
        throw new ClassCastException(activity.toString() + " must implement OnCompleteListener");
    }
    super.onAttach(activity);
}

  @Override
  public void onClick(View v) 
  {
    Log.d(LOG, "Dialog 1: " + ((Button) v).getText());
      switch (v.getId()) {
    case R.id.butlevel1:
      level=1;
      break;
    case R.id.butlevel2:
      level=2;
      break;
    case R.id.butlevel3:
      level=3;
      break;
    }
      mListener.onComplete(level); 
     Toast.makeText(getActivity(),getActivity().getString(R.string.alert_levelvub)+" "+((Button) v).getText(), Toast.LENGTH_SHORT).show();
    dismiss();
  }
