android : Relative layout width wrap_content

Question

I have following layout:

<RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal" >

    <ImageView
        android:id="@+id/personal_image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:src="@drawable/dom_logo_new" />

    <ImageView
        android:id="@+id/round_corner_top_left"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/corner_white_left_top" />

    <ImageView
        android:id="@+id/round_corner_top_right"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/corner_white_right_top" />

    <ImageView
        android:id="@+id/round_corner_bottom_left"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:src="@drawable/corner_white_left_bottom" />

    <ImageView
        android:id="@+id/round_corner_bottom_right"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:src="@drawable/corner_white_right_bottom" />

</RelativeLayout>

There is 1 main image (personal_image) and 4 small images.

I need display main image (personal_image) at center horizontal of the screen with 4 images at its each corner (top left, top right, bottom left, bottom right). but RelativeLayout has width and height of all screen.

How can I set the width and the height of RelativeLayout the same width and height of personal_image??

</RelativeLayout>
</LinearLayout>

As you are using wrap content you donot have to worry about different screen sizes.it will manage by its own.

我建议您使用9补丁而不是角落图像，这是Android解决此类问题的方法。
