Vimalatha, to change your background when you click a button just add this code to the onClick function of your button.

 myLinearLayout.setBackgroundColor(Color.BLUE);

Assuming that myLinearLayout is your LinearLayout name...

To set the theme dynamically at runtime, call setTheme() in your activity's onCreate() method, before calling setContentView(). To change the theme, you simply need to restart your activity.

Here is a nice tutorial on how dynamically apply themes.

and this one too.

you can use a particular theme for a given xml file. in graphical layout you can CHANGE the theme of the layout using editing config.

use onclick event to go to next layout and here your theme will be different from the first one.

Sorry but you can't change styles programmatically.

how to set the Style Attribute Programmatically in Android?

There are certainly other methods to achieve this desired behavior however. You could set onclick listeners for each button, and programmatically change text size, color, background etc of your various view elements

Please Visit this link for it.

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:textColor="#00FF00"
    android:typeface="monospace"
    android:text="@string/hello" />

<TextView
    style="@style/CodeFont"
    android:text="@string/hello" />

By defining an xml theme file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="CodeFont" parent="@android:style/TextAppearance.Medium">
        <item name="android:layout_width">fill_parent</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:textColor">#00FF00</item>
        <item name="android:typeface">monospace</item>
    </style>
</resources>

You can also apply styles to all activities of an application:

<application android:theme="@style/CustomTheme">

Or just one activity:

<activity android:theme="@android:style/Theme.Dialog">
