android - TabLayout Indicator slides really slow on Tab selection -

-

i'm using tablayout 2 nested fragments , have noticed when user clicks other tab, while content changes immediately, indicator move first tab second takes literally 3-4 seconds.

i have same behavior in device have far tried app (not genymotion). nexus 4 , nexus 5x of testing devices.

the layout :

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:emvideoview="http://schemas.android.com/apk/res-auto" android:background="@color/white" android:clickable="true" android:layout_width="match_parent" android:layout_height="match_parent">  <com.devbrackets.android.exomedia.emvideoview     android:id="@+id/video_play_activity_video_view"     android:layout_width="match_parent" android:layout_height="360dp"     emvideoview:defaultcontrolsenabled="true"/>  <android.support.design.widget.tablayout     android:id="@+id/nested_tabs" android:layout_below="@+id/video_play_activity_video_view"     android:layout_width="match_parent" android:layout_height="?attr/actionbarsize"     app:tabmode="fixed" app:tabgravity="fill"/>  <framelayout android:id="@+id/fl_nested_tabs_container" android:layout_below="@+id/nested_tabs"     android:layout_width="match_parent" android:layout_height="wrap_content"/>

and code change tabs :

@override public void ontabselected(tablayout.tab tab) {     if (iscommentsfragmentselected) {         iscommentsfragmentselected = false;         getchildfragmentmanager()                 .begintransaction()                 .replace(r.id.fl_nested_tabs_container, pollsfragment.newinstance())                 .commit();     } else {         iscommentsfragmentselected = true;         getchildfragmentmanager()                 .begintransaction()                 .replace(r.id.fl_nested_tabs_container, commentsfragment.newinstance())                 .commit();     }  }

i using nested fragments in 3 tab layout viewpager. setting offscreen page limit solved slow loading problem me.

viewpager.setoffscreenpagelimit(2);
