TextView android:ellipsize="end" 问题

Question

在我的应用程序中，我使用了ellipsized 我的TextView，因此如果文本太大，它会在最后使用android:ellipsize="end" 显示...。

例如，文本 ABCDEFGHIJKLMNOPQRSTUVWXYZ 显示为 ABCDEFGHIJ...。但是当文本很小时，例如ABCDEF，它仍然在末尾显示...，使文本看起来像AB...。我无法修复 textview 的宽度，因为在其他地方使用了相同的 textview，但有一些不同的宽度要求。我应该怎么做才能使其工作并仅在文本足够大时才显示...。

Answer 1

//在你的文本视图中

还添加以下属性

android:maxEms="8"
android:singleLine="true"

注意：您可以根据要显示的字符数调整 em 大小。
