android - Unwanted padding around an ImageView -

i need include header graphic in of activities/views. file header called header.xml:

<?xml version="1.0" encoding="utf-8"?> <framelayout xmlns:android="http://schemas.android.com/apk/res/android"   android:layout_width="fill_parent"    android:layout_height="wrap_content"   android:background="#0000ff"    android:padding="0dip">    <imageview xmlns:android="http://schemas.android.com/apk/res/android"     android:src="@drawable/header"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:layout_margin="0dip"     android:layout_margintop="0dip"     android:layout_marginbottom="0dip"     android:padding="0dip"     android:paddingtop="0dip"     android:paddingbottom="0dip"     android:layout_gravity="fill"     android:background="#00ff00"     /> </framelayout> 

note android:background="#00ff00" (green), it's visualisation purposes.

i include them views this:

<?xml version="1.0" encoding="utf-8"?> <linearlayout   xmlns:android="http://schemas.android.com/apk/res/android"   android:layout_width="fill_parent"   android:layout_height="fill_parent"   android:orientation="vertical"   style="@style/white_background">    <include layout="@layout/header" />   (...) 

so, when try out, result looks left image, instead of should (right):

(1) - orange - part image/imageview in question
(2) unloved green border. note: normally, green area transparent - it's green because set background.

note green border around image @ top; it's part of imageview , can't figure out why there or how can rid of it. set paddings , margins 0 (but result same when omit them) . image 480x64px jpeg* , put in res/drawable (not in 1 of drawable-xdpi though).

(* jpeg, because seems stumbled upon old png gamma problem - @ first worked around problem making green border same orange picture, , colors didn't match.)

i tried on htc desire/2.2/build 2.33.163.1 , on emulator. described problem in #android-dev; reproduce problem had no explanation either. build target 1.6.

update @tehgoose: code yields exact same top+bottom padded result.

<?xml version="1.0" encoding="utf-8"?> <linearlayout   xmlns:android="http://schemas.android.com/apk/res/android"   android:layout_width="fill_parent"   android:layout_height="fill_parent"   android:orientation="vertical"   style="@style/white_background">    <!-- <include layout="@layout/header" />  -->    <imageview     android:src="@drawable/header"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:background="#00ff00"     android:layout_weight="0"     />    <linearlayout     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:orientation="vertical"     android:padding="8dip"     android:layout_weight="1">      (... rest of elements)    </linearlayout> </linearlayout> 

finally!

<imageview   (...)   android:adjustviewbounds="true" /> 

the adjustviewbounds attribute did trick:

set true if want imageview adjust bounds preserve aspect ratio of drawable.

i stumbled upon here. help!
