Java中定义Map常量，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");
