I want to place the relative layout (last relative layout which having 3 buttons it, after scrollview ) at the bottom my screen. but its not happening

what to do??

Edited: The happening is i statically placed the relative layout by specifying padding, when running in portrait mode i made it fix at bottom but when i changed to landscape its not at bottom. How to place relativelayout in bottom in either cases??

Thanks

Add following line to your Relative layout

android:layout_alignParentBottom="true"

This must be work.

Happy coding.

Here the solution I tested and which works :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent" android:layout_height="100dp"
        android:layout_weight="1.0" android:fadingEdge="none">
    ...
    </ScrollView>

    <RelativeLayout android:orientation="horizontal" 
        android:layout_width="fill_parent" android:layout_height="60dip" 
        android:background="@drawable/tabbarbottom">

        <Button android:id="@+id/jobs" android:text="About Us"
            android:layout_width="100dp" android:layout_height="fill_parent"
            ...></Button>

        <Button android:id="@+id/aboutus" android:text="Value"
            android:layout_width="100dp" android:layout_height="fill_parent"
            ...></Button>

        <Button android:id="@+id/benefits" android:text="History"
            android:layout_width="fill_parent" android:layout_height="fill_parent" ...></Button>

    </RelativeLayout>
</LinearLayout>

The first LinearLayout should have layout_height="fill_parent". This way it takes up the whole screen.
The ScrollView should have a small fixed height, and an extra android:layout_weight="1.0" : it will take up whatever space is remaining.
The RelativeLayout should have a fixed height (it will always take up the same space at the bottom of the screen), and the Buttons inside of it should have layout_height="fill_parent" (to have the same height as the RelativeLayout).

Make parent layout as relative layout. layout which contain button put that on bottom using

android:layout_alignParentBottom="true"

This will work

In the ScrollView

android:fillViewport="false"

@Udaykiran Hey Your Code for XMl is ok please check here i put your code with some change and i found only one change in this Relative Layout
