ImageButton behind ImageView and offset

问题

So I'm working on making a design for my app and I need to put a imagebutton directly below an imageview. But since my imageview has a border around it with a drop shadow I need to hide (shift up) maybe 10 pixels of my imagebutton behind my imageview. Here is a quick drawing of what I want.

I hope that makes sense. I've been messing around with all kinds of different arrangements but I cant get what I want. Any help would be greatly appreciated.

First of all use a RelativeLayout. Add first the ImageButton and then the ImageView, in this way the ImageView will be on top of your ImageButton. Then you should set on your ImageButton the following :

<ImageButton
    ....
    android:layout_below="@id/ImageViewId"
    android:layout_marginTop="-10px" />

Use relative layout as said. Refer http://developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html for more positions and easy design.

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >

    <Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/Imageview"
    android:layout_marginTop="-16dp" />

<ImageView
    android:id="@+id/Imageview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="46dp"
    android:adjustViewBounds="true"
    android:contentDescription="@string/description_logo"
    android:src="@drawable/imagename" />



    </RelativeLayout>
