我有一个带抽屉布局的活动,工具栏包含如下:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<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">
<include
android:id="@+id/tool_bar"
layout="@layout/tool_bar"
>
</include>
<!-- The main content view -->
<FrameLayout
android:id="@+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
<!-- The navigation drawer list-->
<android.support.v7.widget.RecyclerView
android:id="@+id/RecyclerView"
android:layout_width="280dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#ffffff"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.DrawerLayout>
工具栏如下所示:
<?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">
</android.support.v7.widget.Toolbar>
对于此活动,我继续添加/替换片段@ id / frame_container
现在我的情况是我有一个包含2个标签的片段,这些标签又将回收者视图提供给视图寻呼机: 我在java中设置如下:
TabLayout tabLayout = (TabLayout) rootView.findViewById(R.id.tab_layout2);
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
viewPager = (ViewPager) rootView.findViewById(R.id.pager2);
adapter = new MyFragmentAdapter(
getFragmentManager(), 2);
viewPager.setAdapter(adapter);
tabLayout.setupWithViewPager(viewPager);
此片段的布局:
<RelativeLayout ...
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v4.view.ViewPager
android:layout_marginTop="@dimen/abc_action_bar_stacked_max_height"
android:id="@+id/pager2"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="@id/tab_layout"
/>
</RelativeLayout>
视图寻呼机中的片段具有回收者视图。:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/listViewPO"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginBottom="2px">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
问题是当我尝试滚动时,操作栏没有隐藏。我无法弄清楚这个问题。我花了几天时间。请帮忙!
