我一直在嘗試使用少量的指導在這裏實現了RecyclerView一個CollapsingToolbar:http://android-developers.blogspot.co.uk/2015/05/android-design-support-library.html,這裏的項目:https://github.com/chrisbanes/cheesesquare,我目前有以下佈局:CoordinatorLayout與RecyclerView&CollapsingToolbarLayout
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="@dimen/detail_backdrop_height"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true"
app:theme="@style/Toolbar"
app:contentScrim="@color/primary"
app:expandedTitleMarginStart="48dp"
app:expandedTitleMarginEnd="64dp">
<ImageView
android:id="@+id/backdrop"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
app:theme="@style/Toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
<android.support.design.widget.FloatingActionButton
android:layout_height="wrap_content"
android:layout_width="wrap_content"
app:layout_anchor="@id/appbar"
app:layout_anchorGravity="bottom|right|end"
android:src="@drawable/ic_directions"
android:layout_margin="@dimen/fab_margin"
android:clickable="true"/>
</android.support.design.widget.CoordinatorLayout>
源如下:
setContentView(R.layout.activity_details_image);
final Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
loadImage();
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle(formatName(getIntent().getStringExtra("name")));
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
ArrayList<DetailsAdapter.Detail> details = new ArrayList<DetailsAdapter.Detail>();
details.add(new DetailsAdapter.Detail("Main Facilities", "Children's Play Area, Ecotricity Electric Vehicle Charging Point, Lucky Coin, Multi Faith Room (southbound only), Showers", R.drawable.ic_moto));
details.add(new DetailsAdapter.Detail("Restaurants", "Eat & Drink Co., Burger King, Costa, West Cornwall Pasty Co. (northbound only), Greggs, Costa Express, Krispy Kreme", R.drawable.ic_moto));
details.add(new DetailsAdapter.Detail("Shops", "WHSmith, M&S Simply Food, Fone Bitz, Cotton Traders, Ladbrokes (southbound only)", R.drawable.ic_moto));
details.add(new DetailsAdapter.Detail("Motel", "Travelodge", R.drawable.ic_moto));
details.add(new DetailsAdapter.Detail("Forecourt", "BP (with: LPG), Costa Express, Air1 AdBlue", R.drawable.ic_moto));
DetailsAdapter mAdapter = new DetailsAdapter(this, details);
recyclerView.setAdapter(mAdapter);
recyclerView.setItemAnimator(new DefaultItemAnimator());
我沒有摺疊式工具測試,它滾動精細
但是,即使列表比可見部分長,它也不會滾動。我做錯了什麼?
我試着用一個簡單的RecyclerView使用你的佈局,它工作的很好。問題可能與項目的數量有關,或者可能與適配器的實現有關? – razzledazzle
它沒有工具欄,就像我說的。適配器和項目都很好。你能上傳你的項目嗎? – Kieron
實際上,爲了測試我修改了項目Cheesesquare,我唯一做的事情是在項目中使用RecyclerView替換細節視圖中的NestedScrollingView,它工作正常。 – razzledazzle
