我想让用户在其中一个选项卡Toolbar
中滚动时折叠(由 提供)。TabLayout
ViewPager
这是我想要的功能:
但是,我的布局不仅不滚动,而且还截断了底部的内容(准确地说,它截断了 48dp - 工具栏的高度):
我使用 ViewPager 将每个 Fragment 显示为选项卡。片段由一个简单的ScrollView
持有 a组成TextView
。这是布局:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/ueber_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:layout_scrollFlags="scroll|enterAlways" />
<android.support.design.widget.TabLayout
android:id="@+id/ueber_tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:tabIndicatorColor="@android:color/white"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/ueber_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
每个片段都有以下布局:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/ueber_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="14sp"
android:textColor="#000000"
android:linksClickable="false"
android:textColorLink="#000000"
android:fontFamily="serif"
android:padding="16dp"/>
</ScrollView>
ViewPager 由 ViewPagerAdapter 设置:
ViewPager viewPager = (ViewPager) findViewById(R.id.ueber_viewpager);
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new ContentFragment(), "Über");
adapter.addFrag(new ContentFragment(), "Impressum");
adapter.addFrag(new ContentFragment(), "Lizenzen");
viewPager.setAdapter(adapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.ueber_tabLayout);
tabLayout.setupWithViewPager(viewPager);
