Android : ImageButton Width & Height

Question

I have ImageButton that has a scr from an image I added to the drawble-hdpi folder called imgholder, this image Width = 96pix and Height = 96px

but when I check on the Height and Width for the ImageButton in its click event I get 128!

Why is that? where did the extra came from and how to resolve this so the ImageButton has same width as the src image. Thanks

<ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/ibAddImage1"
    android:src="@drawable/imgholder"
    android:layout_above="@+id/tvAddReviseCaption"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:background="@android:color/transparent" />

"px" changes device to device. You should use dp for layout_width and layout_height android:layout_width="96dp" android:layout_height="96dp"
