Simply do one thing cut the amount of code that you want in scrollview.... Now add scrollview in place of the code that u just "cut" ... now scrollview also have a child layout as linear layout.... in that linear layout make height to be wrap_content..... next place your code inside that linear layout... ListView outside the scrollayout...
[code]--------- Ctrl+X
replace with
<ScrollView>
<LinearLayout>
[code]-------- Ctrl+V
enter code here
</LinearLayout>
</ScrollView>
<ListView> -------- here add listview

How to add footer to the layout?

This is my layout.xml in which i want to add a fixed footer at the bottom of listview.Also, it's not possible for me to change my current layout.This layout contains an action bar at the top.The very first relative layout contains all layout including action bar relative layout to below of which i have a frame layout containing listview.I want this listview to have a footer fixed at the bottom containing some image buttons.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<!-- This acts as Actionbar -->
<RelativeLayout
android:id="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="50dp"
android:paddingRight="10dp"
android:orientation="horizontal"
android:background="#drawable/action_bar_background_strip" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="20dp"
android:clickable="true"
android:onClick="toggleMenu"
android:contentDescription="#null"
android:src="#drawable/drawer_toggle_button" />
<View
android:id="#+id/View1"
android:layout_width="1dp"
android:layout_height="fill_parent"
android:layout_marginLeft="20dp"
android:layout_toRightOf="#+id/imageView1"
android:background="#ffffff" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_toRightOf="#+id/View1"
android:layout_marginTop="8dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="115dp"
android:text="Listview"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#ffffff"

android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:contentDescription="#null"
android:src="#drawable/icon" />
</RelativeLayout>
<FrameLayout
android:layout_below="#+id/relativeLayout"
android:layout_width="match_parent"

For example you can: create new layout for your footer and place it at bottom of its parent and make your FrameLayout to be placet above your footer
Use android:layout_above and android:layout_alignParentBottom properties of your layouts...
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!-- This acts as Actionbar -->
<RelativeLayout
android:id="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="50dp"
android:paddingRight="10dp"
android:orientation="horizontal"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="20dp"
android:clickable="true"
android:onClick="toggleMenu"
android:contentDescription="#null" />
<View
android:id="#+id/View1"
android:layout_width="1dp"
android:layout_height="fill_parent"
android:layout_marginLeft="20dp"
android:layout_toRightOf="#+id/imageView1"
android:background="#ffffff" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_toRightOf="#+id/View1"
android:layout_marginTop="8dp"
android:layout_marginLeft="20dp"
android:layout_marginRight="115dp"
android:text="Listview"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#ffffff"
android:textStyle="bold" />
<View
android:id="#+id/View2"
android:layout_width="1dp"
android:layout_height="fill_parent"
android:layout_toRightOf="#+id/textView1"
android:background="#ffffff" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:contentDescription="#null" />
</RelativeLayout>
<FrameLayout
android:layout_below="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/linearLayout">
<ListView
android:id="#+id/listView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:choiceMode="multipleChoice">
</ListView>
</FrameLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/linearLayout">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button" />
</LinearLayout>

Make a footer.xml like below:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50dp"
android:background="#5E616B"
android:gravity="center_horizontal"
android:orientation="horizontal"
android:weightSum="1" >
<ImageButton
android:id="#+id/btn_one"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="15dp"
android:layout_marginTop="2dp"

The idea here is simple.Take a linear layout with weightsum 1 and divide that weight to their childs.Here I have taken 5 imagebuttons and distributed .2 weight to each of them.Dont forget to set the layout orientation to vertical.
Then include the footer in your layout like:
<include
android:id="#+id/footer"
layout="#layout/footer" />
Then design your SCROLLVIEW as:
<FrameLayout
android:layout_below="#+id/relativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/footer"
android:layout_below="#+id/header"(IF ANY) >
<ListView
android:id="#+id/listView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:choiceMode="multipleChoice" >
</ListView>
</FrameLayout>

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/linearLayout1" >
</ListView>
<!-- Footer linear layout -->
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="55dp"
android:weightSum="5"
android:layout_marginBottom="-5dp"

android:layout_alignParentBottom="true" >

android:layout_marginLeft="-4.5dp"

android:layout_marginTop="-5dp"

android:layout_toRightOf="#+id/flightLogo"
android:text="Rs 20,000" />
</RelativeLayout>

I can't tell if this is your only problem yet but when you use layout_weight inside of a vertical LinearLayout then your layout_height should be 0dp.
Likewise if it is inside of a horizontal LinearLayout then the layout_width should be 0dp. Also, all of the layouts should have a weight if you are using it on one of thenm.
android:layout_below= in your third LinearLayout, I believe, is not a property of LinearLayout. That is a property of RelativeLayout.
My suggestion for this type of setup is to use RelativeLayout as the root layout. Then, for your header LinearLayout you can use android:layout_alignParentTop="true" and for your footer use android:layout_alignParentBottom="true" then stick your ListView in the middle with android:layout_below="#id/idOfHeaderLL"
<RelativeLayout
...>
<LinearLayout
android:id="#+id/headerLL"
android:layout_alignParentTop="true"
...>
<!-- add header veiws -->
</LinearLayout
<ListView
android:layout_below="#id/headerLL"
.../>
<LinearLayout
android:layout_alignParentBottom="true"
...>
<!-- add footer views -->
</LinearLayout>
</RelativeLayout>
I'm not going to rewrite the whole layout but that should give you an idea. The "..." is where you will put in your other properties such as height, width, etc...

The part with the scrollview displays at maximum size and is not scrolling.
The two buttons at the end are not displayed, they apparently don't fit in the screen.
I'd like to have the scroll working in order to have buttons appearing.
Why the scrolled layout is displayed at max size instead of being scrolled?
What would be the solution?

For making the buttons to appear in the screen you should have the buttons within the scroll too. Mostly, the screens that you design should have scrollview as the parent if the screen contains many components. Main ScrollView -> LinearLayout / RelativeLayout -> Add Components as needed. By doing so you should have be able to see the buttons also. In doing this way even if your layout changes to landscape the components wont get hidden and will be shown in the scroll. Hope you get my point and it helps you in solving your issue.
As far as the code above is concerned you will not be able to see the buttons as buttons are not within scrollview and hence the view below is hidden.

If doesn't scroll because its height is wrap_content.

As ChristopheCVB stated, your ScrollView needs to NOT be wrap_content. A ScrollView will only scroll if the content it contains is larger (read taller for a vertical ScrollView and wider for a horizontal ScrollView) that the ScrollView itself. If it is smaller, then it has no need to scroll.
