Set the scaleType to fitStart in your XML:

<ImageView
    android:id="@+id/ivMap"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="fitStart" >
</ImageView>

You can use ImageView.ScaleType.MATRIX and set image matrix using ImageView.setImageMatrix(). Matrix can be obtained using Matrix.setRectToRect() method.

Please check Terel's answer, which is said to be the correct answer.

Depending on what else is in the layout, a solution could be to use another layout (i.e. a FrameLayout which is rather light) in place of the ImageView, and have the ImageView in place of the actual image, with its android:layout_gravity="top".
