android怎么把json转换为hashmap

在android中把json转换为hashmap，代码如下：

import java.util.HashMap;

import java.util.Iterator;

import java.util.List;

import java.util.Map;

import java.util.Map.Entry;

import net.sf.json.JSONArray;

import net.sf.json.JSONException;

import net.sf.json.JSONObject;

expressOrder.setSendPhone(reserJson.getString("sendPhone"));

expressOrder.setSendAddress(reserJson.getString("sendAddress"));
