Scrollview not working for Relative Layout

I am trying to populate a Relative layout with 4 card views in it. Each cardview consists one image and a text view. I wrapped all the card views in a relative layout and the relative layout in a scroll view. It's not working. If I remove scrollview, its working fine. Tried by putting scrollview inside the relative layout. But didnt work
Code:

Hope this will help you.. (this snippet worked in my case)

</RelativeLayout>
</ScrollView>

you have written the scroll view tag wrong. That's the reason its not working. Change it from <Scrollview> to <ScrollView> and add the Scroll view end tag like </ScrollView>and re run the project, it will work fine.
Hope this will help you !

1) You've misspelled the ScrollView tag it must be <ScrollView> not <Scrollview>
2) You didn't close the <ScrollView> tag at the end of the code

ScrollView applied only to LinearLayout child instead of the LinearLayout itself

I´m trying to make a scrollview but it is getting itself applied on the 2 lists I have in the LinearLayout, scrollview child. I want to be able to scroll, vertically, through the entire layout, but it only lets me scroll on the lists. What did I do wrong and could it be fixed?
Thanks in advance

How it is being displayed:

where can I add include in my xml file?

I'm trying to add a toolbar in my xml files.
So I made toolbar.xml and I need to include it in upload.xml:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_upload"
android:layout_width="match_parent"
android:padding="10dp"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.sk.mf.Upload"
android:background="#fff">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageToUpload"
android:layout_gravity="center_horizontal"
android:layout_width="150dp"
android:layout_height="150dp" />
<EditText
android:id="#+id/etUploadName"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<Button
android:id="#+id/bUploadImage"
android:text="Upload Image"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
the problem is, anywhere I place it I had error like:
scrollview can host only one direct child (inside scrollview)
multiple root tags (after scrollview)
...
my question here is, where and how can I put the code below in the xml above?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent">

</RelativeLayout>

try this : wrap your layout in LinearLayout and the toolbar tag
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Android Relative Layout with sticky footer

I'm relatively new to Android development and I'm having a hard time putting together a certain interface. I've looked through many similar questions but none of them give me the answer i'm looking for.
I want to put together an XML interface like the following:
I want a LinearLayout that acts like a sticky footer that will contain two Buttons. This part will always align to the bottom and and will always be 60dp high. The RelativeLayout would then be on top of the footer, but it's height should scale depending on the screen size.
I've tried the following:
<LinearLayout 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:orientation="vertical"
tools:context=".DartboardActivity">
<RelativeLayout
android:id="#+id/game_layout"
android:layout_width="match_parent"
android:layout_height="506dp"
android:background="#drawable/background"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<ImageView
android:id="#+id/Dartboard"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/desc_dartboard"
android:src="#drawable/dartboard" />
<hhs.week3.dartboard.VerticalSeekBar
android:id="#+id/seekBarVertical"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="bottom"
android:thumb="#drawable/thumbhorizontal"
android:layout_marginBottom="40dp" />
<SeekBar
android:id="#+id/seekBarHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:thumb="#drawable/thumbhorizontal" />
</RelativeLayout>
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="60dp"
android:background="#333">
<Button
android:id="#+id/fire"
style="#style/button"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:text="#string/fire" />
<Button
android:id="#+id/settings"
style="#style/button"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:text="#string/settings" />
</LinearLayout>
</LinearLayout>
I got it working half decently, but it requires me to give the RelativeLayout bit a fixed height, making it look right on my phone, but not on others.
How do I best approach this?

Use the LinearLayout layout_weight mechanism to assign all remaining space to your RelativeLayout:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
... />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="60dp"
... />
</LinearLayout>

Try following code
<RelativeLayout 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:orientation="vertical"
tools:context=".DartboardActivity" >
<RelativeLayout
android:id="#+id/game_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/buttons"
android:layout_alignParentTop="true"
android:background="#drawable/ic_launcher"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin" >
</RelativeLayout>
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_alignParentBottom="true"
android:background="#333"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
I removed LinearLayout and replaced with RelativeLayout. This will allow you to set your LinearLayout stick to bottom.

I was able to achieve the same result by using below code. Basically, the parent layout is one Linear layout and the first child element is a scrollview so it can squeeze its content when the keyboard is shown. Also note the use of the android:layout_height="0dp" and android:layout_weight="1" used with the scrollview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/wrap"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/wrap2"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
</LinearLayout>
</ScrollView>
<FrameLayout
android:id="#+id/buttonsPanel"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#333" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="action buttons" />
</FrameLayout>
</LinearLayout>

Try this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
