我的猜测是，丢失的结束锚标签导致了问题。我猜HTML解析器不喜欢空的锚标记：

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>";

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

你在logcat中有错误吗？

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