ListView的项目无法点击与Horizo​​ntalScrollView内 [英] ListView items not clickable with HorizontalScrollView inside

问题描述

我有一个相当复杂的的ListView 。每个项目看起来是这样的：

I have quite a complicated ListView. Each item looks something like this:

> LinearLayout (vertical)
  > LinearLayout (horizontal)
    > include (horizontal LinearLayout with two TextViews)
    > include (ditto)
    > include (ditto)
  > TextView
  > HorizontalScrollView (this guy is my problem)
    > LinearLayout (horizontal)

在我的活动，在创建项目时（ getView（）称）我添加动态的TextView 取值到的LinearLayout 在 Horizo​​ntalScrollView （除了填充其他的，更简单的东西了）。令人惊讶的，性能pretty的好。

In my activity, when an item is created (getView() is called) I add dynamic TextViews to the LinearLayout inside the HorizontalScrollView (besides filling the other, simpler stuff out). Amazingly, performance is pretty good.

我的问题是，当我加入了 Horizo​​ntalScrollView ，我的列表中的项目变得不可点击。他们没有得到橙色背景点击时，他们不火 OnItemClickedListener 我已经设置了（做了一个简单的 Log.d 电话）。

My problem is that when I added the HorizontalScrollView, my list items became unclickable. They don't get the orange background when clicked and they don't fire the OnItemClickedListener I have set up (to do a simple Log.d call).

我怎样才能让我的列表中的项目可点击一次？

How can I make my list items clickable again?

编辑：设置安卓descendantFocusability =blocksDescendants在最上面的的LinearLayout 似乎工作。我想知道是否有其他的方法，虽然：？如果我想在我的列表中的项目可成为焦点的项目

setting android:descendantFocusability="blocksDescendants" on the topmost LinearLayout seems to work. I'd like to know if there are other ways, though: what if I want focusable items in my list items?

推荐答案

使用安卓descendantFocusability =blocksDescendants在最上面的的LinearLayout 的伎俩。里面的元素仍可以点击，他们只是没有作为焦点（即你不能按他们的非触摸屏设备上）。好足够了。

Using android:descendantFocusability="blocksDescendants" on the topmost LinearLayout did the trick. Elements inside can still be made "clickable", they're just not focusable (i.e. you can't click them on a non-touchscreen device). Good enough for me.
