在android中顯示中文字符

Question

我試圖使用PHP傳遞數據（來自服務器），數據由中文字符組成。 我試圖使用我設法檢索數據的JSON解析器解析數據，但數據（中文）顯示為??? 。 誰能告訴我出了什么問題？

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;

    }

正如我的logcat所見。

Answer 1

我的db已經默認為utf8，遇到同樣的問題。

添加通常的元標記“”后，問題仍然存在。

然后我創建了一個專用的connection.php來確保與mysql的所有通信都是charset utf8，注意mysqli_set_charset（$ bd，'utf8'）中的utf8中沒有“ - ” ！

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() ;
    }

?>

這是發送檢索數據的示例。

<?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
?>

解決了。 您需要在utf8中對POST進行編碼。

 if(method == "POST"){
            // request method is POST
            // defaultHttpClient

            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new UrlEncodedFormEntity(params,"utf-8")); <------ utf8

Answer 3

public static String test(){
String testResult= "";
try {
    HttpGet get = new HttpGet("http://xxxxx");//edit url removed.
    DefaultHttpClient httpclient = new DefaultHttpClient();
    HttpResponse response = httpclient.execute(get);
    String result = EntityUtils.toString(response.getEntity());
    JSONObject obj = new JSONObject(result);
    if(!obj.isNull("title")){
        testResult= obj.getString("title");
        Log.d("Test","Test1:"+ testResult);
    }
} catch (JSONException e) {
    e.printStackTrace();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
return testResult;//

}

從這段代碼中獲取幫助..這肯定會對你有所幫助..享受

Answer 4

您不提供檢索數據的代碼段。 這是我猜測源字符集是UTF-8，相應地替換你的源編碼。

InputStreamReader isr = new InputStreamReader(new ByteArrayInputStream(str.getBytes(Charset.forName("UTF-8"))), Charset.forName("UTF-8"));

str是你的json字符串。

更新：似乎您使用iso-8859-1檢索，因此嘗試將您的代碼更新為UTF-8 。

注意：JSON文本的字符編碼始終為Unicode。 UTF-8是唯一在線上有意義的編碼，但也允許使用UTF-16和UTF-32（ 源 ）。
