try :

<imageview android:id="@id/imgview" android:layout_width="fill_parent" android:layout_height="wrap_content" android:adjustviewbounds="true" android:scaletype="fitcenter" />   android:adjustviewbounds = "true" 

will when images larger imageview. not strech image shrink it.

android:scaletype="fitcenter" 

for times when image smaller imageview, strech image width of parent.
