安卓:TextView的自动截断并替换最后3字符字符串 [英] Android: TextView automatically truncate and replace last 3 char of String
问题描述
如果一个字符串
长于的TextView
的宽度,自动折到下一行。单线(德precated)或通过设置安卓:inputType =文本$ C $我可以用
安卓避免这种情况C>。我现在需要的是什么,我替换
字符串
的最后3个字符 ... 。因为我不使用等宽字体,这将永远是不同,这取决于我在使用的字母串
。所以,我不知道什么是得到了的TextView
字符串中的最后3个字符,并取代它们的最好方法。也许有一些已经在Android框架内实现的,因为这必须是一个常见的问题。
If a String
is longer than the TextView
's width it automatically wraps onto the next line. I can avoid this by using android:singleLine
(deprecated) or by setting android:inputType="text"
. What I need now is something that replaces the last 3 characters of my String
with "...". Since I'm not using a monospace font this will always be different depending on the letters used in my String
. So I'm wondering what's the best way to get the last 3 characters of a String in a TextView
and replace them. Maybe there's already something implemented in the Android framework, since this must be a common problem.
推荐答案
您应该能够使用ellipsize文本视图的属性:
You should be able to use the "ellipsize" property of a text view:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/text_mytext"
android:ellipsize="end"
android:singleLine="true"
/>
您可能还需要重力值适用于布局也;我有时看到自动伸展没有他们的看法。
You may also need to apply gravity values to the layout too; I have sometimes seen "auto-stretching" views without them.
