让背景小图不是拉伸而是多个重复

<xml version="1.0" encoding="utf-8"?><LinearLayoutandroid: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">

<bitmap
xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/tile"
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);

<?xml version="1.0" encoding="utf-8"?><bitmap    xmlns:android="http://schemas.android.com/apk/res/android"    android:src="@[package:]drawable/drawable_resource"    android:antialias=["true" | "false"]    android:dither=["true" | "false"]    android:filter=["true" | "false"]    android:gravity=["top" | "bottom" | "left" | "right" | "center_vertical" |                      "fill_vertical" | "center_horizontal" | "fill_horizontal" |                      "center" | "fill" | "clip_vertical" | "clip_horizontal"]    android:tileMode=["disabled" | "clamp" | "repeat" | "mirror"] />
