View jumps and blinks instantly, though animateLayoutChanges="true"


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.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>


    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        android:visibility="gone"
        app:tabGravity="fill"
        app:tabIndicatorColor="@android:color/white"
        app:tabMode="fixed"/>

</android.support.design.widget.AppBarLayout>

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <!--
        This FrameLayout holds my fragments.
    -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/outer_background">

        <ProgressBar
            android:id="@+id/main_load_progress"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:indeterminate="true"/>
    </FrameLayout>

    <include
        android:id="@+id/left_drawer_full"
        layout="@layout/navigation_drawer"
        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?


Solution

  • 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);
