android - IllegalStateException : ScrollView can host only one direct child -

i have fragment, comprises of scrollview has single linearlayout(i have wrapped other linearlayouts this)

fragment_details.xml

 <scrollview      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"      tools:context=".detailsactivityfragment">       <linearlayout...>  </scrollview> 

in detailsactivity i'm adding fragment

detailsactivity.java

 detailsactivityfragment fragment = new detailsactivityfragment();         fragment.setarguments(b);          getsupportfragmentmanager().begintransaction()                 .add(r.id.movie_details,fragment)                 .commit(); 

activity_details.xml

<fragment android:id="@+id/movie_details" 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:name=".detailsactivityfragment" tools:ignore="mergerootframe"/> 

but when run program following error:

java.lang.runtimeexception: unable start activity componentinfo{...}: java.lang.illegalstateexception: scrollview can host 1 direct child 

i have followed threads on issue of scrollview, i'm not able solve this. please!!

use frame layout instead of fragment in activity_details bcoz fragment used when u have fixed fragment show. here u r showing ur movie detail fragment using again u r inflating fragment(another instance of movie detail fragment) in ur activity , creates problem.
