Android 滑动视图+；标题栏-更改标题名称

带有导航的活动模板 类型：滑动视图+标题栏 选项创建一个包含三个片段部分的应用程序，一个紧凑的标题栏标题（在Android设计指南中称为可滚动选项卡）和基于滑动视图设计模式的各部分之间的滑动导航

那么我该如何更改标题栏中默认的章节1,2,3我想重命名这些章节有什么想法吗

在

部分SPAGERAAdapter

中，更改

getPageTitle（int位置）

获取相应页面的页面标题。

抱歉，没有问题，谢谢你的帮助：）快速问题我需要做什么？每个SwipeView/选项卡打开一个类文件，如Activity1.java 2,3。查看页面用于加载

片段

s。我发了一篇关于如何添加带有图像图标的相应页面标题的图像的新帖子。（图标+标题）。
