上一页和下一页可见的Android ViewPager?

Android ViewPager with previous and next pages visible?(上一页和下一页可见的Android ViewPager?)

问题描述

我目前正在构建一个水平视频库.

I am currently building a horizontal gallery of videos.

我想制作这样的东西，只有一个视频居中，上一个和下一个视频的一部分:

I'd like to make something like that with only one video centered and part of previous and next videos:

我首先选择了 Gallery，但它的局限性让我看了为了别的东西.我想显示一个页面指示器，但使用 Gallery 很难实现.

I first opted for a Gallery but its limitations made me look for something else. I'd like to show a page indicator and it is quite difficult to implement using a Gallery.

第二种选择是选择 来自 Android 兼容性库的 ViewPager.我找到了一种在其上实现 页面指示符 的方法.但是现在，如何部分显示左右页面呢?

The second option was to go for a ViewPager from Android Compatibility library. I found a way to implement a page indicator over it. But now, how to partly show left and right pages?

推荐答案

我使用负页边距来部分显示下一页和上一页.fading edge 属性可用于使上一页/下一页淡化:

I used a negative page margin to partly show the next and the previous pages. The fading edge property can be used to make previous/next page fade:

ViewPager examplePager = (ViewPager) findViewById(R.id.exampleView);
examplePager.setPageMargin(-50);
examplePager.setHorizontalFadingEdgeEnabled(true);
examplePager.setFadingEdgeLength(30);

此功能还需要最新的支持包(2011 年 10 月第 4 版)

The lastest support package (revision 4, October 2011) is also required for this to work
