Expanding on plowman s answer  here is the non-deprecated version of changing the background image with java    Override public void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       Bitmap bmp   BitmapFactory decodeResource getResources                R drawable texture       BitmapDrawable bitmapDrawable   new BitmapDrawable getResources   bmp       bitmapDrawable setTileModeXY Shader TileMode REPEAT              Shader TileMode REPEAT       setBackground bitmapDrawable

Ok  here s what I ve got in my app  It includes a hack to prevent ListViews from going black while scrolling   drawable app background xml    lt  xml version  1 0  encoding  utf-8   gt       lt bitmap xmlns android  http   schemas android com apk res android          android src   drawable actual pattern image          android tileMode  repeat    gt    values styles xml    lt  xml version  1 0  encoding  utf-8   gt   lt resources gt      lt style name  app theme  parent  android Theme  gt       lt item name  android windowBackground  gt  drawable app background lt  item gt       lt item name  android listViewStyle  gt  style TransparentListView lt  item gt       lt item name  android expandableListViewStyle  gt  style TransparentExpandableListView lt  item gt     lt  style gt      lt style name  TransparentListView  parent   android style Widget ListView  gt       lt item name  android cacheColorHint  gt  android color transparent lt  item gt     lt  style gt      lt style name  TransparentExpandableListView  parent   android style Widget ExpandableListView  gt       lt item name  android cacheColorHint  gt  android color transparent lt  item gt     lt  style gt    lt  resources gt    AndroidManifest xml       lt application android theme   style app theme  gt

Here is a pure-java implementation of background image repeating    Override public void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       Bitmap bmp   BitmapFactory decodeResource getResources    R drawable bg image       BitmapDrawable bitmapDrawable   new BitmapDrawable bmp       bitmapDrawable setTileModeXY Shader TileMode REPEAT  Shader TileMode REPEAT       LinearLayout layout   new LinearLayout this       layout setBackgroundDrawable bitmapDrawable       In this case  our background image would have to be stored in res drawable bg image png
