1、jackson 泛型
ObjectMapper objectMapper = null;
String json = “{\"list\":[{\"picUrl\":\"aa\",\"picDescr\":\"uu\"}，{\"picUrl\":\"aa\",\"picDescr\":\"uu\"}，{\"picUrl\":\"aa\",\"picDescr\":\"uu\"}]}”;
Map<String, Scenery[]> map = null;
objectMapper = JsonFactory.getInstance().getObjectMapper();
map = objectMapper.readValue(json,new TypeReference<Map<String, Scenery[]>>(){});
2、jackson 自定义对象
ObjectMapper objectMapper = null;
Picture picture = null;
String json = “{\"pic\":\"aa\",\"picurl\":\"aaa\"}”;
objectMapper = JsonFactory.getInstance().getObjectMapper();
picture = objectMapper.readValue(json, Picturet.class);
//类型还可以是： Map.class Picture[].class
3、android 隐藏标题栏
requestWindowFeature(Window.FEATURE_NO_TITLE);
