while surfing web i found a piece of code relating your problem ... use it if you found it worthy

to auto adjustment of image add the following property to your image view as written below

for xml

android:scaleType="fitXY"

for java

myImageView.setScaleType(ScaleType.FIT_XY);

you should set the image's height and width wrap_content and the layout wrapping this image with fill_parent it will solve the problem and re size the image automatically as below is example for better understanding of what i am saying

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"


>

<ImageView
 android:layout_width="wrap_content" 
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="@drawable/myImage"
 />
 </LinearLayout>
