Question

在我的应用程序中，我ellipsize为TextView，因此如果文字过大，最后会使用...显示android:ellipsize="end"。

egText ABCDEFGHIJKLMNOPQRSTUVWXYZ显示为ABCDEFGHIJ...。但是当文字较小时，例如ABCDEF，它仍会在结尾显示...，使文字看起来像AB...。我无法修复textview的宽度，因为在其他地方使用相同的textview有一些不同的宽度要求。我应该怎么做才能使它工作，只有当文本足够大时才显示...。

Answer 1

//在你的textview中

还添加以下属性

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

注意：您可以将ems大小调整为您想要显示的字符数。
