刷卡次数+标题地带 - 更改标题名 [英] Swipe Views + Title Strip - change title name

问题描述

使用导航的BlankActivity模板
类型：刷卡次数+标题地带
 选择创建一个具有三个片段部分的应用程序，一个紧凑的标题条标题（称为滚动标签Android的设计指南）和部分之间滑动导航的基础上，刷卡视图设计模式。

凭什么我改一下标题条默认其section1,2,3说我要重命名的章节任何想法如何？

解决方案

在你的 SectionsPagerAdapter ，修改 getPageTitle（INT位置）来获取页面标题为相应的页面。

The BlankActivity template with the Navigation Type: Swipe Views + Title Strip option creates an application with three Fragment sections, a compact title strip header (known as Scrollable Tabs in the Android Design guide) and swipe navigation between the sections, based on the swipe view design pattern.

so how can i change what the title strip says for default its section1,2,3 i want to rename the sections any ideas how?

解决方案

In your SectionsPagerAdapter, change the getPageTitle(int position) to get the page titles for the corresponding pages.
