Android的布局片段/活动混乱 [英] Android Layout Fragment/Activity Confusion

问题描述

我在做我的第一个Android应用程序与ActionBarSherlock。

I am making my first android application with the ActionBarSherlock.

应用程序将始终有一个操作栏由3个选项卡（默认选择第一个选项卡）。 该应用程序可扩展为与平板电脑使用。

The application will always have an action bar consisting of 3 tabs (first tab selected by default). The app could be extended for use with a tablet.

我一直在寻找的网页，并按照Android开发指南，但是我发现了一些东西混淆。 第一个选项卡的屏幕会随着项目的清单列表视图，onitemselected应该向用户发送到屏幕其特点有关该项目的更多细节。

I have been searching the web, and following the android development guides, however I am finding a few things confusing. The first tab screen will be a list view with a list of items, onitemselected should send the user to a screen which features more details about that item.

当我应该用一个片段？如果每个选项卡是一个片段？ 或者，应该每个标签调用一个新的活动，其中包括片段？ 而且，如果使用的片段，我应该将它们放置在不同的类别，或活动??

When should I use a fragment? Should each tab be a fragment? Or, should each tab call a new activity, which consists of fragments? And, if using fragments, should I place them in different classes, or embed them within an activity??

鸭preciate任何帮助，谢谢。

Appreciate any help, thanks.

推荐答案

我与碎片的经验主要是在ViewPager，所以我不能完全肯定它是否适用于这里。

My experience with Fragments is mostly on ViewPager, so I am not entirely sure if it applies here.

在Android的，你应该使用尽可能多的片段。根据经验，一般情况下，假设你要翻译的用户界面从手机到平板电脑，元素，可以住在一起，在相同的配置应该是一个片段。

In Android, you should use Fragments as much as possible. As a general rule of thumb, imagine you are translating the UI from phones to tablets, elements that can stay together in the same configuration should be a Fragment.

有一个片段子类，称为ListFragment，所以你可能要考虑为您的第一个标签。 （ListFragment是碎片像ListActivity是活动）

There is a Fragment subclass called ListFragment, so you might want to look into that for your first tab. (ListFragment is for Fragment like ListActivity is for Activity)

还有一个教程中，我发现处理片段。没有真正考虑它，但我希望它能帮助。

There is also a tutorial I found to deal with fragments. Did not really look into it but I hope it helps.

至于动作条/ ActionBarSherlock，我绝对没有经验withit所以有人可能要补充。

As for ActionBar / ActionBarSherlock, I have absolutely no experience withit so someone might want to add to that.
