文本換行

Question

我需要做的新聞列表，所以我有一個拇指和兩個文本實現自定義listfield並將其與graphics畫object.it都走了罰款，給我造成的預期，但也有一些問題， 文本包木窗我基本上是Android開發者和有wrap content文件允許設置自動textfiled但在這種情況下，有超過第二個文本綁定。我有指客戶listfield from here

這裏是屏幕::

你需要做的方案，我們沒有標籤字段列表中，因爲我們正在繪製的圖形使用它。 所以我用來做一個解決辦法這樣做，我計算沒有像素availabale爲我的文字自定義字體，它就會多大的存儲空間，我將有三個時期的跡象給。 您可以使用此代碼，如果，它可以幫助你，在地方graphics.drawText的使用下drawListRow方法

String name =(String)ht.get("title"); 
xTotal= f2.getAdvance(name); 
xAvail= Display.getWidth() - <bitmap>.getWidth() - 30; 
if(xTotal > xAvail) 
{ 
forLabel= name.length() * xAvail/xTotal ; 
    name = name.substring(0, forLabel - 3) + "..."; 

} 

使用名稱字符串變量。
