Android程序錯誤

我已經把這個Android程序寫成了新聞源...它工作得很好，直到 - 當前 - 關於focal.ie的文章。因此，前6個故事加載正常，但它沒有加載其餘的和Im破壞我的頭試圖找出原因。任何幫助，將不勝感激。這是代碼。謝謝Android程序錯誤

logcat中有錯誤嗎？ – 2011-03-17 20:16:16

我的猜測是缺少閉合錨定標記導致問題。我猜的HTML解析器不喜歡空錨標籤：

String temp2 = "<a href=\"" + temp + "\"/>"; 
String newImg = temp2 + "<img src=\"" + url + "\"/ width =100 >"; 
test2 = test2 + "<tr>";

應該是：

String temp2 = "<a href=\"" + temp + "\" >"; 
String newImg = temp2 + "<img src=\"" + url + "\"/ width =100 >" + "</a>"; 
test2 = test2 + "<tr>";

和：

test2 = test2 + " " + txt.get(i-1).text() + " " + temp2;

應該是：

test2 = test2 + temp2+ " " + txt.get(i-1).text() + " </a>";
