Android - ImageView has somewhat like a padding -

i have weird problem. or maybe got wrong. imageview has padding. looks this:

so "myimage" supposed align topmost. instead when check graphical layout image adjusted lower. it's whole image green broken line.

 <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/master_background">  <imageview     android:id="@+id/toppage"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:src="@drawable/image" />  </relativelayout> 

this code. tried change src background image adjusted. how can adjust image. application doesn't have window title.

use android:adjustviewbounds="true" in image view.

<imageview     android:id="@+id/toppage"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:adjustviewbounds="true"     android:src="@drawable/image" />
