java map常量定义
https://www.cnblogs.com/leonxiaosi/p/6928604.html
Java中定义Map常量,List常量
一般的方式的使用静态代码块。比如:
|
1
2
3
4
5
|
public final static Map map = new HashMap(); static { map.put("key1", "value1"); map.put("key2", "value2"); } |
下面为一种简单定义Map常量的方式
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
public final static Map<String, Fragment> NAV_ITEM_ADPTER = new HashMap<String, Fragment>() { { put("拍录传", new CameraFragment()); put("集群对讲", new GroupTalkFragment()); put("视通", new VideoCallFragment()); put("位置", new PositionFragment()); put("浏览", new BrowseFragment()); put("消息", new MsgFragment()); put("群组", new GroupFragment()); put("设置", null); put("退出", null); }}; |
List的话则可以这样定义:
|
1
|
public final static List<String> LIST = Arrays.asList("one","two","three"); |
