I used to add a single Fragment
to my Activity
in onCreate
. I've switched to using a ViewPager
with a FragmentPagerAdapter
. Now the "burger" in the action bar is always an arrow, and doesn't animate when opening the drawer.
How can I have the ActionBarDrawerToggle
be a "burger" when the drawer is closed, animate to an arrow when opening, and then animate back to a "burger" when closing, while still keeping the ViewPager
?
EDIT: Here's the layout of the Activity
(SlidingTabLayout
taken from here)
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/itp_blue">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.itpvoip.dev.orange.widgets.SlidingTabLayout
android:id="@+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="@+id/drawer_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
<ListView
android:id="@+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:paddingTop="8dp"
android:paddingBottom="8dp"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="?colorPrimaryDark">
</ListView>
</android.support.v4.widget.DrawerLayout>
The issue was that some of the
Fragment
s were altering theActionBar
's display state. Cleaning that up helped get the animation back.
