TextView android：ellipsize =「end」issue

在我的應用程序中，我有ellipsize d我的TextView，所以如果文字太大，最後會顯示...使用android:ellipsize="end"。TextView android：ellipsize =「end」issue

例如文本ABCDEFGHIJKLMNOPQRSTUVWXYZ顯示爲ABCDEFGHIJ...。但是當文字很小時，如ABCDEF它最後仍會顯示...使文字看起來像AB...。我無法修復textview的寬度，因爲相同的textview在其他地方使用時有一些不同的寬度要求。我應該做些什麼才能使它工作，並且只有當文字足夠大時才顯示...。

向我們展示了您用於textview的XML。我有一種感覺，你使用'android：layout_width =「wrap_content」' – Blundell 2012-03-26 11:06:24

你可以嘗試使用android：ellipsize =「marquee」。 – YuviDroid 2012-03-26 11:07:29

with'android：layout_width =「wrap_content」'它仍然不應該ellipsize文本...也許任何父容器有一個寬度的限制.. – pleerock 2012-03-26 11:11:03

//在你的TextView

還添加以下屬性

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

注：可以調整EMS大小，你要多少個字符顯示。

非常感謝。這就是訣竅。 – Rajkiran 2012-03-26 12:05:15

有用的答案。 EMS不直接轉換爲字符數。 – 2014-05-01 16:52:07

這會將我的行數減少到2.它也可以設置爲3行。和ellipsize也工作正常。 – 2012-09-04 13:47:56
