Put a button over an ImageView

Try this code... it's Help you....

<?xml version="1.0" encoding="utf-8"?>  
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   android:orientation="vertical"   
   android:layout_width="fill_parent"  
   android:layout_height="fill_parent">  

 <ImageView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/imageviewMain"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:src="Path "
/>
<Button android:id="@+id/but2" 
     android:layout_width="wrap_content" 
         android:layout_height="wrap_content" />
</RelativeLayout>

Try this Code .....

In that give paramater in button to set your Button Position....

android:layout_margin or android:layout_alignParent

And also give Path of Image....

Don't put the image as a background, you don't have any control on how the image is scaled. Instead, create a RelativeLayout, and put an ImageView as one of the child, and you can place anything (buttons etc) as other RelativeLayout children.

<RelativeLayout ...>
    <ImageView (your image) ...>
    <Button (the button you want) ... />
</RelativeLayout>

There is another way to do it,http://www.curious-creature.org/2009/03/01/android-layout-tricks-3-optimize-part-1/
