 先上图：

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

backrepeat.xml

<bitmap 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:src="@drawable/repeatimg" 
    android:tileMode="repeat" 
    android:dither="true" /> 

代码方式：

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.icon);
BitmapDrawable bd = new BitmapDrawable(bitmap);
bd.setTileModeXY(TileMode.REPEAT , TileMode.REPEAT );
bd.setDither(true);
view.setBackgroundDrawable(bd);
