Because my app is slow to do fragment transition

0
My app slows (and crashes, but does not crash) after I click on a button that does a fragment transition, it was working normal, I was moving in another area of the app and when I came back, this way.

Fragment containing onclick

public class PreparacaoFragment extends Fragment implements View.OnClickListener {
    public PreparacaoFragment() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_preparacao, container, false);
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        int[] BUTTON_IDS = {
                R.id.btndia1,
                R.id.btndia2,
                R.id.btndia3,
                R.id.btndia4,
                R.id.btndia5,
                R.id.btndia6,
                R.id.btn_exercicios
        };

        List<FancyButton> buttons = new ArrayList<>();

        for(int id : BUTTON_IDS) {
            FancyButton button = view.findViewById(id);
            button.setOnClickListener(this);
            if (id != R.id.btn_exercicios){
                button.setEnabled(false);
                buttons.add(button);
            }else{
                button.setEnabled(true);
                buttons.add(button);
            }

        }
        for (int i = 0; i < 4 ; i++) {
            buttons.get(i).setEnabled(true);
        }

    }

    @Override

                args.putIntArray("layouts",layouts);
                break;
