Java 将滑动功能和文本视图添加到图像幻灯片Android应用程序-漫画

我需要将滑动功能和文本视图添加到图像幻灯片Android应用程序的实现中——这实际上是一个关于圣堂博斯科生活的漫画，其中包含与故事相关的图像。Gallery widget完成了这项工作，但遗憾的是，现在已被弃用：(

我设法做到了以下几点，只有单击底部的缩略图才能在图像之间导航：

此代码示例没有可用的缩略图，也没有指示刷卡的左/右箭头。我不知道如何实现这些。请提供一些帮助？

您好

你试过android的ViewPager组件吗

如果没有，请通过。这是一个非常有用的组件。它 解决了你所有的问题

:

若画廊出了问题，那个就去找安卓的组件

该项目分为三个任务。第一个任务是构建所有图像的网格视图显示。第二个任务是在全屏滑块中显示选定的网格图像。最后在全屏图像中添加收缩缩放功能

查看教程，可能有助于您实现您的目标

ViewPager在android中用于滑动功能。这是非常有用的ViewPager库，感谢您提供的很棒的库！它看起来很完美，但我不知道如何在我当前的项目中使用它。请编辑上面粘贴的代码，并向我展示samplecirclesdefault lay出去？请？谢谢你的回答！：）事实上，这个项目非常简单，不需要GridView和收缩缩放功能。是否有可能以某种方式“沉默”该教程，并且只实现当前的基本需求那太棒了谢谢你的回答！：）我尝试过这个，但它没有滑动功能，“上一个”、“下一个”按钮在导航后并不总是刷新自己（有没有办法编辑我当前的代码来实现底部带有文本视图的viewpager？我不太擅长java：(
