Ellipsize not working for textView inside custom listView
提问by aspartame
I have a listView with custom objects defined by the xml-layout below. I want the textView with id "info" to be ellipsized on a single line, and I've tried using the attributes
我有一个 listView，其中包含由下面的 xml-layout 定义的自定义对象。我希望将 ID 为“info”的 textView 在一行上进行省略，并且我尝试使用这些属性
android:singleLine="true"
android:ellipsize="end"
without success.
没有成功。
If I set the layout_width to a fixed width like e.g.
如果我将 layout_width 设置为固定宽度，例如
android:layout_width="100px"
the text is truncated fine. But for portability reasons this is not an acceptable solution.
文本被截断得很好。但出于便携性原因，这不是一个可接受的解决方案。
Can you spot the problem?
你能发现问题吗？

Ellipsize is broken (go vote on the bug report, especially since they claim it's not reproducible) so you have to use a minor hack. Use:
Ellipsize 坏了（对错误报告进行投票，特别是因为他们声称它不可重现）所以你必须使用一个小技巧。用：
android:inputType="text"
android:maxLines="1"
on anything you want to ellipsize. Also, don't use singleLine, it's been deprecated.
在任何你想要椭圆化的地方。另外，不要使用singleLine，它已被弃用。
UPDATE:
更新：
On closer inspection, the problem you're having is that your table is extending off the right side of the screen. Changing your TableLayoutdefinition to:
仔细检查后，您遇到的问题是您的桌子超出了屏幕的右侧。将您的TableLayout定义更改为：
<TableLayout
android:id="@+id/info_table"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="5px"
android:paddingTop="10px"
android:shrinkColumns="1">
should fix that problem, then do what I said above to ellipsize your TextView.
应该解决该问题，然后按照我上面所说的将您的TextView.

Without using deprecated properties, the following lines work great for me
不使用已弃用的属性，以下几行对我很有用
android:ellipsize="end"
android:lines="1"
android:scrollHorizontally="true"

I had the same results as Steve:
我得到了与史蒂夫相同的结果：
android:ellipsize="marquee" android:scrollHorizontally="true" android:lines="1"
android:ellipsize="marquee" android:scrollHorizontally="true" android:lines="1"
works perfectly
完美运行

try...
尝试...
i.e.
IE
android:ellipsize="marquee"
android:focusable="true" android:marqueeRepeatLimit="num|marquee_forever"
android:lines="1" android:focusableInTouchMode="true"
android:scrollHorizontally="true"
as marquee only works when view is selected or focused according to the comment#2 on http://code.google.com/p/android/issues/detail?id=5364
因为选取框仅在根据http://code.google.com/p/android/issues/detail?id=5364上的评论 #2 选择或聚焦视图时才有效

After checking out these 3 issues(closed & re-opened) and previous posts, I think the key is to wrap up TextView with a outer LinearLayout(or any other layout you are using), and set the "layout_width" of outer layout width a little bit SMALLERthan the text length contained in the TextView. Seems has to LIMITthe width to make the "android:ellipsize" behave properly.
在检查了这 3 个问题（关闭并重新打开）和以前的帖子后，我认为关键是用外部 LinearLayout（或您正在使用的任何其他布局）包装 TextView，并设置外部布局宽度的“ layout_width”一点点SMALLER，不包含在TextView的文本长度。似乎必须限制宽度才能使“android:ellipsize”正常运行。
Follow the tip in this issue, after adding all these attributes for hacking, I also set the layout_width of outer LinearLayout to 240dp for example:
按照本期提示，在添加所有这些属性后，我还将外部 LinearLayout 的 layout_width 设置为 240dp 例如：
<Linearlayout
android:layout_width="240dp"
android:layout_height="wrap_content"
...>
<TextView
....
android:singleLine="true"
android:lines="1"
android:maxLines="1"
android:scrollHorizontally="true"
android:ellipsize="end"
android:text="this is a text which length should be longer than 240dp"
/>
</LinearLayout>
Than I can successfully make the end of TextView displaying "...", not very acceptable but it works! And I think it works whether used in regular TextView or a TextView in a List Adapter.
比我可以成功地使 TextView 结束显示“...”，不是很可接受，但它有效！而且我认为无论是在常规 TextView 还是 List Adapter 中的 TextView 中使用，它都有效。
Here's my screenshot for the result!

For me these attribute worked. I tested on API 8 and onwards
对我来说，这些属性有效。我在 API 8 及以后的版本上进行了测试
In XML
在 XML 中
<TextView
....
android:maxLines="1"
android:scrollHorizontally="true"
android:ellipsize="end"
....
/>
Programmatically
以编程方式
setMaxLines(1);
setEllipsize(TruncateAt.END);
setHorizontallyScrolling(true);

If you put TextView inside a custom ViewGroup you created, make sure to measure it again if you changed the dimension after the measurement.
如果您将 TextView 放在您创建的自定义 ViewGroup 中，如果您在测量后更改了尺寸，请确保再次测量它。
E.g., I calculated the new dimension in onLayout. Before you call child.layout, call
例如，我在 onLayout 中计算了新维度。在调用 child.layout 之前，调用
measureChild(child,
View.MeasureSpec.makeMeasureSpec(childWidth, View.MeasureSpec.EXACTLY),
View.MeasureSpec.makeMeasureSpec(childHeight, View.MeasureSpec.EXACTLY));
