logcat中有错误吗？ – 2011-03-17 20:16:16

我的猜测是缺少闭合锚定标记导致问题。我猜的HTML解析器不喜欢空锚标签：

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

应该是：

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;

应该是：

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