android ImageButton do not stretch image

Question

How can I prevent the ImageButton from stretching the image?

Using this snippet:

 <ImageButton
                android:src="@drawable/prediction"
                android:background="?android:attr/selectableItemBackground"
                android:gravity="center_horizontal"
                android:scaleType="centerInside"
                android:layout_height="wrap_content"
                android:layout_width="wrap_content"
                android:contentDescription="some description"
                android:text="@string/predict"
                local:MvxBind="Click ExecuteQueryCmd" />

I get the following effect:

Image is 64x64 png.

All I want is for the ImageButton to respect native width and length, hence resolution, of the image it is being assigned. Recommendations based on a similar post is to use a Button, set its background to an image then use custom selectors but this sounds like a hack. Or is this the proper way to do this?

It work for me with

  <ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:background="@android:color/transparent"
    android:contentDescription="some description"
    android:scaleType="centerInside"
    android:src="@drawable/ci_icon"
    android:text="@string/predict"
    local:MvxBind="Click ExecuteQueryCmd" />

Put your image in android:src attribute
