Как исправить искажение фрагмента при нажатой кнопке?

Question

У меня есть фрагмент с этим макетом:

Если я нажимаю одну кнопку, я получаю список в Recyclerview, все отображается нормально, но при нажатии на спине у меняискажение кнопки:

Вот xml первого фрагмента:

    <?xml version="1.0" encoding="utf-8"?>

Это код фрагмента:

public class FragmentCategoryEvents extends Fragment {
    private Button btn_auto;

    private Button btn_corsa;
    private Button btn_bicicletta;

    public FragmentCategoryEvents() {
        // Required empty public constructor
    }


    public static FragmentCategoryEvents newInstance() {
        FragmentCategoryEvents fragment = new FragmentCategoryEvents();
        return fragment;
    }


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view =  inflater.inflate(R.layout.fragment_fragment_category_events, container, false);
        return view;
    }
    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState){
        super.onViewCreated(view, savedInstanceState);

    }

    private void getCategoryEvents(String category){
        FragmentShowCategory newFragment = new FragmentShowCategory();
        FragmentTransaction transaction = getFragmentManager().beginTransaction();
        Bundle bundle = new Bundle();
        bundle.putString("category_key",category);
        newFragment.setArguments(bundle);
        transaction.replace(R.id.category_events_layout,newFragment);
        transaction.addToBackStack(null);
        transaction.commit();
    }



    // TODO: Rename method, update argument and hook method into UI event
    public void onButtonPressed(Uri uri) {

    }

    @Override

        super.onAttach(context);

    }

    @Override

}

Вкл. Кнопка нажата У меня есть такой макет:

    <?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.SwipeRefreshLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/swipe_container_category"

            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </android.support.v4.widget.SwipeRefreshLayout>

                .subscribeOn(Schedulers.io())

    }

    private void handleResponse(ArrayList<Evento> eventos) {
        RecyclerViewAdapter adapter = new RecyclerViewAdapter(eventos);
        LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
        mRecyclerView.setLayoutManager(layoutManager);
        mRecyclerView.setAdapter(adapter);
        mSwipeRefreshLayout.setRefreshing(false);

    }

    public void onButtonPressed(Uri uri) {

    }

    @Override

    }

    }

    public interface OnFragmentInteractionListener {
        // TODO: Update argument type and name
        void onFragmentInteraction(Uri uri);
    }
}

Как я могу решить эту проблему?

Answer 1

Решено удаление атрибутов layout_columnWeight и layout_rowWeight и настройка параметров layout_width и layout_height в Cardview.
