java - ImageView padding above and below image -

i trying set image of imageview byte array this:

bitmap bitmap = bitmapfactory.decodebytearray(imagedata, 0, imagedata.length); imageview imageview = (imageview)findviewbyid(r.id.imageview); imageview.setimagebitmap(bitmap); 

but image appears have quite large black padding @ top , bottom, though actual image data not have these. imageview @ top of linearlayout inside scrollview, ideas?

my imageview designed this:

<imageview android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:id="@+id/imageview"/> 

solved, added

android:adjustviewbounds="true" 

into xml file.
