java - 如何处理来自 Google map 服务器的重音字符(如 République 中的 é)作为 Android 中的响应

Question

我想显示来自 Google map 服务器的响应。我得到的响应是我在将经纬度发送到 Google map 服务器后得到的位置名称，响应是这样的“av de la République”，但是当我在应用程序中显示它之后解析响应，它显示为“av de la RÃ(c)publique”...

下面的代码 fragment 可能有助于理解我的问题..

public static String getAddress(double lat, double lon){
        StringBuilder stringBuilder = new StringBuilder();
         String add ="";

       try {

        HttpPost httppost = new HttpPost("http://maps.googleapis.com/maps/api/geocode/json?latlng="+lat+","+lon+"&sensor=false");
        HttpClient client = new DefaultHttpClient();
        org.apache.http.HttpResponse response;
        stringBuilder = new StringBuilder();

            response = client.execute(httppost);
            HttpEntity entity = response.getEntity();
            InputStream stream = entity.getContent();
            int b;
            while ((b = stream.read()) != -1) {
                stringBuilder.append((char) b);
            }
        } catch (ClientProtocolException e) {
        } catch (IOException e) {
        }

        JSONObject jsonObject = new JSONObject();
        try {
            jsonObject = new JSONObject(stringBuilder.toString());
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

       try {
          add = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
               .getString("formatted_address");
       } catch (Exception e) {
           e.printStackTrace();
       }
       return add;
    }

这是我实现的代码

public static String getAddress(double lat, double lon){
        StringBuilder stringBuilder = new StringBuilder();
         String add ="";
        try {

        HttpPost httppost = new HttpPost("http://maps.googleapis.com/maps/api/geocode/json?latlng="+lat+","+lon+"&sensor=false");
        HttpClient client = new DefaultHttpClient();
        org.apache.http.HttpResponse response;
        stringBuilder = new StringBuilder();


            response = client.execute(httppost);
            HttpEntity entity = response.getEntity();

            char[] buffer = new char[2048];
            Reader reader = new InputStreamReader(entity.getContent(), "UTF-8");
            while (true) {
                int n = reader.read(buffer);
                if (n < 0) {
                    break;
                }
                stringBuilder.append(buffer, 0, n);
            }
        } catch (ClientProtocolException e) {
        } catch (IOException e) {
        }

        JSONObject jsonObject = new JSONObject();
        try {
            Log.i("===================", stringBuilder.toString());
            jsonObject = new JSONObject(stringBuilder.toString());
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


       try {

          add = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
               .getString("formatted_address");

       } catch (Exception e) {
           e.printStackTrace();

       }

       return add;

    }

Answer 1

您正在以字节而不是文本的形式读取文本。金额是多少读取 ISO-8859-1 中的响应，而实际上它是 UTF-8。

试试这个:

char[] buffer = new char[2048];
Reader reader = new InputStreamReader(entity.getContent(), "UTF-8");
StringBuilder stringBuilder = new StringBuilder();

while (true) {
    int n = reader.read(buffer);
    if (n < 0) {
        break;
    }
    stringBuilder.append(buffer, 0, n);
}

此处它已集成到您的代码中:

public static String getAddress(double lat, double lon){
    StringBuilder stringBuilder = new StringBuilder();
    String add ="";

    try {

        HttpPost httppost = new HttpPost("http://maps.googleapis.com/maps/api/geocode/json?latlng="+lat+","+lon+"&sensor=false");
        HttpClient client = new DefaultHttpClient();
        org.apache.http.HttpResponse response;
        stringBuilder = new StringBuilder();
        response = client.execute(httppost);
        HttpEntity entity = response.getEntity();

        char[] buffer = new char[2048];
        Reader reader = new InputStreamReader(entity.getContent(), "UTF-8");
        while (true) {
            int n = reader.read(buffer);
            if (n < 0) {
                break;
            }
            stringBuilder.append(buffer, 0, n);
        }

    } catch (ClientProtocolException e) {

    } catch (IOException e) {

    }

    JSONObject jsonObject = new JSONObject();
    try {
        jsonObject = new JSONObject(stringBuilder.toString());
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    try {
        add = ((JSONArray)jsonObject.get("results")).getJSONObject(0)
        .getString("formatted_address");
    } catch (Exception e) {
        e.printStackTrace();
    }
    return add;
}
