附加一个固定的，透明的，头一个ListView？ [英] Attaching a fixed, transparent, header to a ListView?

问题描述

我一直试图让这个工作有一段时间了...有没有办法把一个透明的头部固定在一个列表视图，所以它看起来有点像这样的：

I've been trying to get this working for some time... Is there any way to put a transparent fixed header on a listview, so it looks kind of like this:

当你向上滚动，头最终会与它下面第1项常规头。

As you scroll up, the header will eventually be a regular header with item 1 below it.

我想我得实现onScrollListener和做一些事情的时候第一个可见的产品列表中的第2项一样，开始用1像素移动列表视图利润率，直到它的标题下方？还是有更好的方法？在一个会怎么做这样的事情任何想法？

I guess I'll have to implement onScrollListener and do something like when the first visible item is item 2 in the list, start moving the listview margins by 1 pixel, until it is below the header? Or are there better ways? Any ideas on how one would do something like that?

推荐答案

我会作出的FrameLayout ......并首先把你的ListView它，填补了屏幕。然后把一个TextView最重要的是。以获得在顶部的希望的行为，可能有一个空白元件在列表0的位置，或者仅仅使列表项0的顶部填充有你头的高度...

I would make a FrameLayout... and put your ListView in it first, filling the screen. Then put a TextView on top of that. To get the desired behavior at the top, maybe have a blank element at position 0 of the list, or just make the top padding of list item 0 have the height of your header...

这是否有意义？ ListView控件应该滚动在的FrameLayout TextView的下方。

Does that make sense? The ListView should scroll underneath the TextView in a FrameLayout.
