我有一个包含以下布局的片段,我在视图寻呼机的帮助下添加了两个片段:
<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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#2096f3"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="@id/tab_layout"
/>
</android.support.design.widget.CoordinatorLayout>
在代码中:
TabLayout tabLayout = (TabLayout) rootView.findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText(tabs[0]));
tabLayout.addTab(tabLayout.newTab().setText(tabs[1]));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
viewPager = (ViewPager) rootView.findViewById(R.id.pager);
adapter = new MyViewPagerAdapter(getFragmentManager(),2);
viewPager.setAdapter(adapter);
我在视图寻呼机的片段中有一个滚动视图。当我开始向下滚动时,我希望操作栏隐藏。怎么做到这一点?
我在活动中有一个工具栏,我正在添加一些片段。如何调整它得到预期的结果:
工具栏:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="@color/background_floating_material_dark"
android:elevation="4dp"
android:paddingTop="1dp"
app:layout_scrollFlags="scroll|enterAlways">

您可以使用自定义样式:
<resources>
<style name = "AppTheme" parent = "android:Theme.Holo.Light.DarkActionBar"></style>
<style name = "HiddenActionBar" parent = "@android:style/Theme.Holo.Light">
<item name = "android:windowActionBar">false</item>
<item name = "android:windowNoTitle">true</item>
</style>
</resources>
并在AndroidManifest.xml上使用它:
<application
android:icon = "@drawable/ic_launcher"
android:label = "@string/app_name"
android:theme = "@style/HiddenActionBar">

此XML代码适合我:
