Android: imageSwitcher fit on screen

Question

I have a problem with imageswitcher to fit on screen. Please check PIC 1. There is still white free space on the edge of the screen. I want to achieve the effect in PIC 2. There is no empty space and imageswitcher perfect fit to screen. I can do this efect with imageView using:

android:scaleType="centerCrop"

but it looks centerCrop doesn't works with imageSwitcher. Thanks for any idea how to fix it.

UPDATE:

Here is my XML code: I added there android:scaleType="fitXY" but it didn't help.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ImageSwitcher
        android:id="@+id/imageswitcher"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"
        android:src="@drawable/it_intro1" >
    </ImageSwitcher>

SOLUTION: finally it helped add this line of code: imageView.setScaleType(ImageView.ScaleType.FIT_XY);

public View makeView() {

            ImageView imageView = new ImageView(Introduction.this);
             imageView.setScaleType(ImageView.ScaleType.FIT_XY);

            LayoutParams params = new ImageSwitcher.LayoutParams(
                    LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

            imageView.setLayoutParams(params);
            return imageView;

        }

In the imageswitcher's xml, set:

 android:scaleType="fitXY"
