我的猜测是缺少关闭锚标签导致问题。我猜测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>";
