Scrollview can host only one direct child
Wrap all the children inside of another LinearLayout with wrap_content for both the width and the height as well as the vertical orientation.
ScrollView can host only one direct child with relativelayout
The Answer given by Md.ibrahim khalil is absolutely right,
Try by replacing your layout with this,

java.lang.IllegalStateException: ScrollView can host only one direct child
Just as the error says
ScrollView can host only one direct child
Wrap the Views inside of a LinearLayout so the ScrollView has only the LinearLayout as a direct child.
From the Docs
A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects. A child that is often used is a LinearLayout in a vertical orientation, presenting a vertical array of top-level items that the user can scroll through.
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
// all the views currently in your ScrollView
</LinearLayout>
</ScrollView>
IllegalStateException : ScrollView can host only one direct child
Use Frame Layout instead of fragment in activity_details bcoz fragment is used when u have a fixed fragment to show.
Here u r showing ur movie detail fragment using it but then again u r inflating another fragment(another instance of movie detail fragment) in ur activity and creates the problem.
HorizontalScrollView can host only one direct child
Meaning, you have to add the imageview to the linearlayout. when you add the image view you are adding it to the HorizontalScrollview which also has a LinearLayout in it ther by adding 2 child elements to the HorizontalScrollView which you cannot do
.IllegalStateException: ScrollView can host only one direct child
No, you have one SrollView inside a LinearLayout. Your ScrollView just has a bunch of TextViews in it. Change it to this:

Backstack exception ScrollView can host only one direct child
You can add a FrameLyout as a child to NestedScrollView and use that FrameLyout as your container. So that the fragment view will always be added to the FrameLyout and NestedScrollView will only have one direct child.
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:fillViewport="true"

<FrameLayout
android:id="@+id/container"
