我有两个布局和ImageViews在里面。第一个布局Imageview将表现为背景和其他布局图像视图作为不同的对象。现在我想放大两个图像的视图，但只应选择对象，而不是背景。我的意思是背景只能用于缩放。放大所有不同布局的ImageViews
这是我的XML
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:id="@+id/test"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/hh_gmw01"
android:scaleType="matrix"
android:tag="0"
/>
<RelativeLayout
android:id="@+id/LParentLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="@+id/imageView100"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="388px"
android:layout_marginTop="269px"
android:contentDescription="Image1"
android:src="@drawable/h1"
android:tag="a" />
<ImageView
android:id="@+id/imageView200"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="147px"
android:layout_marginTop="99px"
android:contentDescription="Image1"
android:src="@drawable/h2"
android:tag="b" />
</RelativeLayout>
</RelativeLayout>
，这是我的ImageView的矩阵代码，但这种大干快上一个imageview的只适用
