How to make an app's background image repeat

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:

<?xml version="1.0" encoding="utf-8"?>    <bitmap xmlns:android="http://schemas.android.com/apk/res/android"        android:src="@drawable/actual_pattern_image"        android:tileMode="repeat" />

values/styles.xml:

<?xml version="1.0" encoding="utf-8"?><resources>  <style name="app_theme" parent="android:Theme">    <item name="android:windowBackground">@drawable/app_background</item>    <item name="android:listViewStyle">@style/TransparentListView</item>    <item name="android:expandableListViewStyle">@style/TransparentExpandableListView</item>  </style>  <style name="TransparentListView" parent="@android:style/Widget.ListView">    <item name="android:cacheColorHint">@android:color/transparent</item>  </style>  <style name="TransparentExpandableListView" parent="@android:style/Widget.ExpandableListView">    <item name="android:cacheColorHint">@android:color/transparent</item>  </style></resources>

AndroidManifest.xml:

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

There is a property in the drawable xml to do it.android:tileMode="repeat"

See this site:http://androidforbeginners.blogspot.com/2010/06/how-to-tile-background-image-in-android.html

Here is a pure-java implementation of background image repeating:

@Overridepublic 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.
