Android的布局:是可重用组件的用户界面可能吗? [英] Android Layout: Is reusable component UI possible?
问题描述
我会preface这一带,我刚开始学习Android的如此温柔。 我来自一个ASP.NET / Silverlight的背景,所以我一直在寻找沿控制线的东西。
I'll preface this with, I've just started learning Android so be gentle. I come from an ASP.NET / Silverlight background so I was looking for something along the lines of controls.
我想重用的布局(一个ListView项模板)的其它布局。
I want to reuse a layout (a ListView item template) in other layouts.
这样的,在我的其他的布局我可以再补充< myListItem />
来显示它
Such that in my other layouts I can just add <myListItem />
to show it.
是这样的,或者类似的东西可能吗?还是有更好的办法吗?
Is this, or anything like it possible? or are there better ways?
推荐答案
这是非常有可能的;你只需要使用&LT;有/&GT;
标记。基本上,你把你的布局在文件中,那么你做的:
This is very possible; you just need to use the <include />
tag. Basically, you put your layout in a file, then you do:
<include layout="@layout/my_list_item_template" />

(安卓文档)
(我假设你想要的是一个可重复使用的布局,而不是自定义组件,所不同的是,可重复使用的布局就像是重复使用标准组件的片段,而自定义组件使用,当你需要扩展的功能一个特定的部件,像一个TextView或按钮,如果你想有一个自定义组件,那么你就必须做很多跑腿到埃里希·道格拉斯的回答更多关于这一点。)
(I am assuming that what you want is a reusable layout, not a custom component. The difference being, a reusable layout is like reusing snippets of standard components, whereas a custom component is used when you need to extend the functionality of a particular widget, like a TextView or Button. If you want a custom component, then you'll have to do a lot more legwork to Erich Douglass' answer for more on that.)
