Фрагмент с карточкой, чтобы заполнить весь экран

Question

Я попытался сделать приложение, используя этот учебник (пример 2). Я создал навигационную панель действий.

Мой основной фрагмент xml (добавлена ​​карточка):

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:card="http://schemas.android.com/apk/res-auto"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context=".MainActivity$PlaceholderFragment"
    android:id="@+id/mainfragment">

    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/scrollView" >

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/abovecards">





            <it.gmariotti.cardslib.library.view.CardListView
                android:id="@+id/myList"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                card:list_card_layout_resourceID="@layout/list_card_thumbnail_layout"
                style="@style/list_card.thumbnail"/>

        </LinearLayout>

    </ScrollView>

</RelativeLayout>

В своей основной деятельности я добавил:

@Override
        public void onActivityCreated(@Nullable Bundle savedInstanceState) {
            super.onActivityCreated(savedInstanceState);
            cardthingy();

        }

        public void cardthingy(){

            int listImages[] = new int[]{R.mipmap.ic_launcher, R.mipmap.ic_launcher1,
                    R.mipmap.ic_launcher, R.mipmap.ic_launcher1, R.mipmap.ic_launcher};

            ArrayList<Card> cards = new ArrayList<Card>();

            for (int i = 0; i<5; i++) {
                // Create a Card
                Card card = new Card(this.getActivity());
                // Create a CardHeader
                CardHeader header = new CardHeader(this.getActivity());
                // Add Header to card
                header.setTitle("Test: " + i);
                card.setTitle("Some text here");
                card.addCardHeader(header);

                CardThumbnail thumb = new CardThumbnail(this.getActivity());
                thumb.setDrawableResource(listImages[i]);
                card.addCardThumbnail(thumb);

                cards.add(card);
            }

            CardArrayAdapter mCardArrayAdapter = new CardArrayAdapter(this.getActivity(), cards);

            CardListView listView = (CardListView) getActivity().findViewById(R.id.myList);
            if (listView != null) {
                listView.setAdapter(mCardArrayAdapter);

                //this I tried from googling possible solutions
                FrameLayout mainy = (FrameLayout) getActivity().findViewById(R.id.container);
                mainy.setLayoutParams(new DrawerLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

                RelativeLayout fragy = (RelativeLayout) getActivity().findViewById(R.id.mainfragment);
                fragy.setLayoutParams(new FrameLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

                ScrollView feed = (ScrollView) getActivity().findViewById(R.id.scrollView);
                feed.setLayoutParams(new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

                LinearLayout rLGreen = (LinearLayout) getActivity().findViewById(R.id.abovecards);
                rLGreen.setLayoutParams(new FrameLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

                listView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

            }



        }

Проблема в том, что он показывает прокручиваемый экран, который заполняет пространство только 1 карты вместо всего экрана:Как вы можете видеть в моих xml и java, я пытался кое-что исправить, но, к сожалению, у меня нет идей.

Answer 1

Хорошо. Решение было довольно простым. Проблема была исправлена ​​удалением scrollview из xml

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/scrollView" >
</ScrollView>

Представление списка карт автоматически становится прокручиваемым после определенного количества элементов.

И следующие строки больше не нужны:

            //this I tried from googling possible solutions
            FrameLayout mainy = (FrameLayout) getActivity().findViewById(R.id.container);
            mainy.setLayoutParams(new DrawerLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

            RelativeLayout fragy = (RelativeLayout) getActivity().findViewById(R.id.mainfragment);
            fragy.setLayoutParams(new FrameLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

            ScrollView feed = (ScrollView) getActivity().findViewById(R.id.scrollView);
            feed.setLayoutParams(new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

            LinearLayout rLGreen = (LinearLayout) getActivity().findViewById(R.id.abovecards);
            rLGreen.setLayoutParams(new FrameLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

            listView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));

Answer 2

Попробуйте изменить

LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT

в

LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.MATCH_PARENT
