Question

我正在创建一个应用程序来监听剪贴板更改并使用一些API来识别语言并获得其含义。问题是某些语言出现在问号上。我认为字符编码存在问题。我不知道如何解决它。

代码：

 //to get language
 static void getLanguage (String s) {
    URL get = null;
    String data = null;
    try {
        get = new URL("https://translate.yandex.net/api/v1.5/tr.json/detect?key=<api_key>&text=" + s);
        Log.d(app_name,get.toString());
        InputStreamReader i_read = new InputStreamReader(get.openConnection().getInputStream());
        data = "";
        int char_read;
        while ((char_read = i_read.read()) != -1) {
            data += (char) char_read;
        }
        int start_index = data.lastIndexOf(":") + 2;
        int end_index = data.lastIndexOf("\"");
        lang = data.substring(start_index, end_index);
        if (lang.equals("")) lang = "en";

    } catch (Exception ex) {
        ex.printStackTrace();
    } finally {
        Log.d(app_name, data);
    }
}

//to get meaning
static public String getDef(String word_string,boolean reTranslate) {
    Log.d (app_name,"got word to define: "+word_string);
    if( !testInet("google.com"))
    {
     Log.d (app_name,"no internet Found");

    }

    String dict_data = "";
    try {
        if (auto_detect_language && !reTranslate)getLanguage(word_string);
        URL get = new URL("https://glosbe.com/gapi/translate?from="+lang+"&dest="+lang_to_translate+"&format=json&phrase=" + word_string+"&tm=true");
        Log.d(app_name,get.toString());
        URLConnection connect = get.openConnection();

        HttpURLConnection   con = (HttpURLConnection) connect;

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));

        String current_line;

        while ((current_line = in.readLine()) != null) {

            dict_data += current_line;
        }
        Log.d (app_name,dict_data);
        con.disconnect();
        in.close();

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

    }

    return dict_data;

}

返回的数据表明这个单词只是问号，虽然它正确显示是logcat。

Answer 1

由于current_line为String，因此无法识别印地语字符。

因为我看到response是正确的。

请使用以下内容阅读response

 BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream(), "UTF-8"));

从剪贴板获得的数据显示为问号。 Android的
