推荐答案

您可以使用RelativeLayout的或AbsoluteLayout，将图像（覆盖它的父）在里面，然后装入activity.Now目前的布局，如果您设置动画的图像，看来你的活动，这样的背景动画。
例如，假设这是你的活动当前布局：

You can use RelativeLayout or AbsoluteLayout ,put an image (that covers it's parent) in it and then mount current layout of activity.Now if you set animation for that image,it seems that background of your activity animates.
For example suppose this is current layout of your activity:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/vg"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />
</LinearLayout>

现在这个布局看起来像previous布局，您可以设置动画图像，它的ID是 IMG1 （它似乎backgr：ound的主要布局）：

Now this layout looks like previous layout and you can set animation for image that it's ID is img1(it seems as backgr:ound of main layout):

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/vg"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >



    <ImageView
        android:id="@+id/img1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_x="0dp"
        android:layout_y="0dp"
        android:src="@drawable/bright_sun" />
    <LinearLayout
    android:id="@+id/vg2"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

        <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" />
    </LinearLayout>

</RelativeLayout>
