How To Set Background Image in an Android Application

It's quite simple to set background image for your android application. Below I have an example code for this as well. Now, just follow the steps..

1. Create a new android application in Eclipse. (click here if you need some help)

2. Copy your image file to /res/drawable directory

  

3. Open your  layout xml file activity_main.xml and add below line;  

android:background="@drawable/bg"
 
Here 'bg' is the name of the image without extension

So final layout file will look like;

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:background="@drawable/bg"

    tools:context=".MainActivity" >

   

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerHorizontal="true"

        android:layout_centerVertical="true"

        android:text="@string/hello_world"/>

4. Run your application. The image will be applied as background for this layout.
