我想排序一个有节点类型( 像这样) 的阵列列表 :
[[country1: null], [name2: null], [city3: null], [region4: null], [name6: null]]
要获取节点名称 I 的值, 请使用函数获取节点Name () so
ArrayNode.get(0).getNodeName() // return country1
我调查了"坚固"的回忆.sort 但我不知道我会怎么做,提前感谢u。

使用 < a href=" "http://docs.oracle.com/javase/6/docs/api/java/util/Comparator.html" rel=“no follow” >Comparator 来定义比较逻辑。
类似的东西:
ArrayList<Node> nodes;
Collections.sort(nodes, new Comparator<Node>() {
@Override
public int compare(Node o1, Node o2) {
return o1.getNodeName().compareTo(o2.getNodeName());
}
});
我想你们要的是 Java. util. comparator. 你可以用它来收藏. sort.
创建 concomparator
, 以节点名称排序, 然后创建 Colections.sort( 列表, 比较员) code>
