Take this repeatable drawable app_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/your_image"
android:tileMode="repeat" />
And use it like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/app_background"/>
And if you want to scale your_image to all screen resolutions, define it as a 9-patch image: http://developer.android.com/tools/help/draw9patch.html
If you want to set through xml, then you need to do as below:
android:background="@android:color/white"
in case if you decide to use android's default color code or if you have colors specified in colors.xml, then use
android:background="@colors/white"
If you want to do programmatically, then do:
linearlayout.setBackgroundColor(Color.WHITE);
and if you want to set an image
android:background="@drawable/image"
You can keep your image in res/drawable folders or create a folder inside res main folder which is name drawable-nodpi which is support all dpi device. and also you can follow Simple Nine-patch Generator
then set background image thus. such as
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/ic_launcher">
Best of luck!
For using a background from drawable folder,
android:background="@drawable/background" >
prepare 4 images and place them in their respective folders.
