Java中定义Map恒量，List常量

public final static Map map = new HashMap();    
static {    
    map.put("key1", "value1");    
    map.put("key2", "value2");    
} 

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);  
    }  
};  

public final static List<String> LIST = Arrays.asList("one","two","three");
