怎么从集合中取出特定集合

Question

这个算是android的json解析吧。
String strJson = "{\"content\":[{\"id\":\"1\",\"tittle\":\"1\",\"content\":\"1\",\"creattime\":\"1\",\"isread\":\"1\",\"mdn\":\"1\"},"
+ "{\"id\":\"2\",\"tittle\":\"2\",\"content\":\"2\",\"creattime\":\"2\",\"isread\":\"2\",\"mdn\":\"2\"}],"
+ "\"size\":2,\"number\":0,\"sort\":"
+ "[{\"direction\":\"ASC\",\"property\":\"creattime\",\"ascending\":true}],"
+ "\"totalPages\":2,\"numberOfElements\":2,\"totalElements\":3,\"firstPage\":true,\"lastPage\":false}";
try {
JSONObject jo = new JSONObject(strJson);
JSONArray jsonArray = (JSONArray) jo.get("content");
for (int i = 0; i < jsonArray.length(); ++i) {
JSONObject o = (JSONObject) jsonArray.get(i);
if ("1".equals(o.getString("id"))) {
System.out.println("id:" + o.getString("id") + ","
+ "tittle:" + o.getInt("tittle") + "," 
+ "content:"+ o.getString("content") + "," 
+ "creattime:"+ o.getString("creattime") + "," 
+ "isread:"+ o.getString("isread"));
}
}
} catch (JSONException e) {
e.printStackTrace();
}应该没问题~你试试
