what I want is the image that’s been swiped need to be enlarged while it’s at the center. I thought I could do it with Gallery. but the example from the android developer is not the one I want. 🙁

If you want to enlarge the center selected image there is one possible way.
On your onItemSelected method, just call an animation to zoom the object. The property of gallery is that it is always center-locked. So the center element will be always selected.
Hope that will work..

<?xml version="1.0" encoding="utf-8"?>
<set
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false"
    android:fillAfter="true"
>
<scale 
       android:fromXScale="1.0"
       android:toXScale="1.50"
       android:fromYScale="1.0"
       android:toYScale="1.50"
       android:duration="600"
       android:pivotX="50%"
       android:pivotY="50%"
       android:fillAfter="true"/>

</set>

Do remember that you will have to store the previous view as when the element is move away from center it should be put to the normal size.

So you can have two views – prevView and currView.
Do the animation on the currView.
