Android:解决客户端从服务器上获取数据乱码的方法

向服务器发送HTTP请求，接收到的JSON包为response，用String content = EntityUtils.toString(response.getEntity(),"utf-8");解码还是出现了中文乱码，在后面加了

String name = new String(response.getBytes("iso-8859-1"), "UTF-8");

也无济于事。想到服务器好像是用URLENCODER编了码的，怀着试一试的态度在return后面加了条URLDecoder.decode(content,"utf-8");果然有效！不过还是不太明白URLDecoder.decode(content,"utf-8")和EntityUtils.toString(response.getEntity(),"utf-8")在解码的时候有什么区别。下面是网络端的代码：

package com.trilink.ibeaconlocationdisplay.utils;

import java.io.UnsupportedEncodingException;
import java.util.List;

import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.params.BasicHttpParams;
import org.apache.http.params.HttpConnectionParams;
import org.apache.http.util.EntityUtils;

import android.util.Log;

public class NetworkService {

private static String TAG = "NetworkService";

//private static String url_ip = ServerUrl.SERVER_ADRESS+"UserInfoServlet?";
//private static String url_ip = "http://192.168.1.231:8080/indoor/";

//创建网络访问处理对象

try{
//执行请求参数

//判断是否请求成功
if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
//获得响应信息
String content = EntityUtils.toString(response.getEntity());
return URLDecoder.decode(content,"utf-8");
}
