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>
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);
image:
The activity has a toolbar but this is outside of the fragment and should not affect the tablayout's ability to have a shadow:
relevant activity 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>
