推荐答案

如果您想要放大的中心选定的图像有一种可能的方式。 在您的onItemSelected方法，只需拨打一个动画缩放的对象。画廊的特性是，它始终是中心锁定。因此，中心元素将被永远选择。 希望将工作..

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>

请记住，你将不得不存储previous视图时，该元件是由中央应该投入到正常大小搬走。

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.

所以，你可以有两种观点 - prevView和currView
请在currView动画。

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