Image streching in list view for multiple resolutions

This question may be off topic but I am really looking for an answer.

I am using list it has image and text (40% image and 60% text). Image is loading from the server. I am using Universal Image loading lib for cache. We are sending image resolutions as 200*200 for all resolution. In some devices it looks little stretch, Is there any way that we can add image width height as per resolution.

Simply I want to download image according to device resolution. but how I will calculate image width and height for different resolutions to fit 40% of list item?

Edit: Added layout xml (List item layout)

<RelativeLayout
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_weight="0.4"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/recommendationlist_image"
        android:layout_width="wrap_content"

        android:contentDescription="@string/app_name"
        android:scaleType="fitXY"
        android:src="@drawable/imgnt_placeholder" />
</RelativeLayout>
