ViewPager活动内容的变化时，幻灯片 [英] ViewPager Activity change content when slide
本文介绍了ViewPager活动内容的变化时，幻灯片的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我一直在四处寻找，但我想不通我怎么能修复了这个问题。
我使用的是@戴夫·莫里西的二次抽样放大图片浏览，是一个伟大的图书馆和它的作品完美，但我想要做一些改变。
对于每一个图像，用户将滑动欲显示具体描述。
所以这将是：
PIC1 | PIC2 | PIC3
DescriptionPic1 | DescriptionPic2 | DescriptionPic3
当我打开它，我可以看到的画面与下面的正确描述，但是当我滑块向左（或右），我可以看到后总是该项目的描述。
是因为方法的getItem（）被调用两次，以使滑块更加流畅。
问题是，我想每个显示画面右下方的内容（介绍）。
我如何展示的内容完全当用户滑动图片？
任何帮助真的是AP preciate。
多谢你们

I've been looking around but I can't figure out how I can fixed this issue. I'm using the @Dave Morrissey's Subsampling Zoom Image View, is a great library and it works perfect, but I want to do a few changes. For each image that the user will slide I want show the specific description. So it will be:
Pic1 |Pic2 |Pic3
DescriptionPic1 |DescriptionPic2 |DescriptionPic3
When I open it I can see the picture with below the right description but when I slide left(or right) I can see always the description of the item after. Happens because the method getItem() get called twice to make the slider more smooth. The problem is that I want show the right content(description) below each picture. How can I show the content perfectly when the user slide the pics? Any help is really appreciate. Thanks guys ViewPagerActivity.java
