材质TabLayout高程不起作用 [英] Material TabLayout elevation not working

问题描述
由于某种原因,材质设计支持库中的新TabLayout上的height属性似乎不起作用.有任何想法吗? XML:
For some reason the elevation attribute does not seem to be working on the new TabLayout in the material design support library. Any ideas? XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="6dp" />
<android.support.v4.view.ViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
像这样在父片段中被钩住了:
hooked up like this in a parent fragment:
ViewPager viewPager = (ViewPager) view.findViewById(R.id.view_pager);
TabLayout tabLayout = (TabLayout) view.findViewById(R.id.tab_layout);
AppPagerAdapter appPagerAdapter = new AppPagerAdapter(getChildFragmentManager());
viewPager.setAdapter(appPagerAdapter);
tabLayout.setupWithViewPager(viewPager);
图片:
该活动具有工具栏,但这在片段之外,并且不应影响布局布局具有阴影的能力:
The activity has a toolbar but this is outside of the fragment and should not affect the tablayout's ability to have a shadow:
相关活动xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.bluckapps.appinfomanager.ui.MainActivity">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
tools:ignore="UnusedAttribute" />
<FrameLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
推荐答案
要显示阴影,必须在TabLayout上设置背景.它可以是与窗口背景相同的颜色(只要它是没有alpha的纯色即可).
To make the shadow show, you have to set a background on your TabLayout. It can be the same color as your window background (as long as it's a solid color with no alpha).
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="6dp"
android:background="@color/white" />
