android - 在android中显示汉字

Question

我正在尝试使用 PHP 传递数据(从服务器)，数据由中文字符组成。我正在尝试使用 JSON 解析器解析数据 我设法检索了数据，但数据(中文)显示为 ???。谁能告诉我哪里出了问题？

下面是我的解析器:

// function get json from url
    // by making HTTP POST or GET method
    public JSONObject makeHttpRequest(String url, String method,
            List<NameValuePair> params) {

        // Making HTTP request
        try {

            // check for request method
            if(method == "POST"){
                // request method is POST
                // defaultHttpClient
                DefaultHttpClient httpClient = new DefaultHttpClient();
                HttpPost httpPost = new HttpPost(url);
                httpPost.setEntity(new UrlEncodedFormEntity(params));

                HttpResponse httpResponse = httpClient.execute(httpPost);
                HttpEntity httpEntity = httpResponse.getEntity();
                is = httpEntity.getContent();

            }else if(method == "GET"){
                // request method is GET
                DefaultHttpClient httpClient = new DefaultHttpClient();
                String paramString = URLEncodedUtils.format(params, "utf-8");
                url += "?" + paramString;
                HttpGet httpGet = new HttpGet(url);

                HttpResponse httpResponse = httpClient.execute(httpGet);
                HttpEntity httpEntity = httpResponse.getEntity();
                is = httpEntity.getContent();
            }           


        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

        // try parse the string to a JSON object
        try {
            jObj = new JSONObject(json);
        } catch (JSONException e) {
            Log.e("JSON Parser", "Error parsing data " + e.toString());
        }

        // return JSON String
        return jObj;

    }

如我的 logcat 所示。

我的数据库已经默认为utf8，遇到同样的问题。

添加了常用的meta标签“”后，问题依旧。

然后我创建了一个专用的 connection.php 以确保与 mysql 的所有通信都是字符集 utf8，请注意 mysqli_set_charset($bd, 'utf8') 中的 utf8 中没有 "-" !

Connection.php

<?php
    $mysql_hostname = "localhost";
    $mysql_user = "username";
    $mysql_password = "password";
    $mysql_database = "dbname";
    $prefix = "";
    $bd = mysqli_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
    mysqli_select_db($bd, $mysql_database) or die("Could not select database");
    if(!mysqli_set_charset($bd, 'utf8'))  {
        exit() ;
    }

?>

这是一个发送检索数据的例子。

<?php

    //Include database connection details
    require_once('connection.php');

        enter code here

    //Create query
    $qry = "SELECT * FROM subject";
    $result = mysqli_query($bd, $qry);
    //  other stuff
?>
