如何使用ListView控件作为滚动型的孩子之一 [英] How do I use ListView as one of the children of a ScrollView

问题描述

我已经阅读了许多文献是说，不这样做的。但他们还没有提供一种替代的解决方案。这个问题似乎来了很多，虽然。这里是我的问题。

I have read a number of literatures that say not to do this. But they have yet to offer an alternative solution. The question seems to come up a lot, though. Here is my problem.

• 我想我的主要布局是滚动（这是因为它具有比可以适应屏幕更多的意见）。我主要布局是垂直的LinearLayout。所以现在我有它里面滚动型

• I want my main layout to be scrollable (this is because it will have more views than can fit the screen). My main layout is a vertical LinearLayout. So for now I have it inside a ScrollView.

我的LinearLayout的许多孩子之一，是一个ListView（显示3项，用户滚动ListView的更多）。

one of the many children of my LinearLayout is a ListView (shows 3 items, user scrolls the ListView for more).

可以像我的LinearLayout的其他孩子是什么将说服你，我需要这个工作：例如，可以是一个滚动的水平的LinearLayout;另一个可能是一个ViewPater;等等。

You can image the other children of my LinearLayout to be whatever will convince you that I need this to work: for example, one may be a scrollable horizontal LinearLayout; another may be a ViewPater; etc.

现在如果我的LinearLayout的内容可以一下子适应屏幕，我也没问题。但是，我有我的LinearLayout大约六个不同的孩子，只有约三在同一时间是可见的。所以，是的，我确实需要能够滚动我的LinearLayout。

Now if the content of my LinearLayout could all fit the screen at once, I would have no problem. But I have about six different children in my LinearLayout and only about three are visible at one time. So, yes, I do need to be able to scroll my LinearLayout.

一件事。如果我滚动孩子ListView和我到达终点，我需要家长的LinearLayout重新开始控制，并开始滚动作为用户滚动。

One more thing. If I am scrolling the child ListView and I reach the end, I need the parent LinearLayout to resume control and start scrolling as user scrolls.

澄清

澄清一点的是，我的ListView实际上是动态添加到一个ViewPager。因此从技术上讲，一个ViewPager是我的LinearLayout的孩子。但随后ViewPager内，其中一个页面是一个ListView。

One clarification is that my ListView is actually dynamically added to a ViewPager. So technically, a ViewPager is the child of my LinearLayout. But then inside the ViewPager, one of the pages is a ListView.

注意

顺便说一句，我看了滚动型内滚动的ListView。答案有好的，但我仍然有一些问题。

By the way, I have read scrolling ListView within ScrollView. The answer there is good, but I still have a few problems.

• 在ListView控件的边缘达到控制不会恢复到滚动型

• once edge of ListView is reached control does not revert to ScrollView

如果任何的LinearLayout的其他子视图点击监听器，那么我不能用它们来滚动滚动型。所以基本上大部分屏幕，滚动视图不滚动的。

If any of the other child views of the LinearLayout have a click listener, then I cannot use them to scroll the ScrollView. So basically for most of the screen, the scroll view is not scrollable.

推荐答案

您可以使用的ListView 为主要布局（而不是滚动型），并把上面的意见与列表 addHeaderView（） -method（以分组的的LinearLayout 或类似的东西），并做下面的列表中的项目一样，用 addFooterView 的的ListView -method 。

You could use the ListView as main layout (instead of the ScrollView) and put the views on top with the lists addHeaderView()-method (grouped in a LinearLayout or something like that) and do the same with the items below the list, with the addFooterView-method of the ListView.

我没有测试它，但我认为它可能工作。

I did not test it, but I think it might work.
