I am making my TabLayout animated by using android:animateLayoutChanges="true" in AppBarLayout. But when I set TabLayout.setVisibility(View.GONE), container for my fragment goes up to ActionBar instantly for a few milliseconds. And then it returns to the end of TabLayout and goes up with it to the ActionBar. I explained this on following gif.
The buttons Theory and Practice are behind the TabLayout for some reason but when hiding TabLayout animation starts FrameContainer that holds my view sticks to the bottom of TabLayout.
I have recorded a video that demostrates this behavior. Dropbox video player skip some frames and animation seems nice. Thats why, to notice the bug, you can load video on computer and watch 5 and 11 second in high quality. Video
My LayoutXML:
<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:orientation="vertical">
<SurfaceView
android:layout_width="0px"
android:layout_height="0px"/>
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animateLayoutChanges="true">

android:id="@+id/drawer_layout"
android:layout_width="match_parent"

<include

android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"/>
</android.support.v4.widget.DrawerLayout>
</android.support.design.widget.CoordinatorLayout>
In addition I am using 23.2.1 support libraries.
How can I fix this blinks and jumps?
Try adding android:animateLayoutChanges="true"
to your view with
app:layout_behavior="@string/appbar_scrolling_view_behavior
so that would be your DrawerLayout. Then enable Transition Type LayoutTransition.CHANGING
on it like so:
ViewGroup layout = (ViewGroup) findViewById(R.id. drawer_layout);
LayoutTransition layoutTransition = layout.getLayoutTransition();
layoutTransition.enableTransitionType(LayoutTransition.CHANGING);
