how to add background image to activity?

Question

using theme or ImageView ?

Answer 1

use the android:background attribute in your xml. Easiest way if you want to apply it to a whole activity is to put it in the root of your layout. So if you have a RelativeLayout as the start of your xml, put it in here:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/rootRL"     android:orientation="vertical"      android:layout_width="fill_parent"     android:layout_height="fill_parent"      android:background="@drawable/background"> </RelativeLayout>
