Проблемы с Android JSON CharSet UTF-8 - PullRequest

/ 30 января 2012

В настоящее время я работаю над приложением Android, которое получает свои данные из API, который предоставляет данные JSON.Я храню элементы для данных JSON в виде строк, что приводит к появлению некоторых странных символов (например, «Â»).Я понимаю, что это связано с набором символов, поэтому я установил InputStreamReader в «UTF-8», но, похоже, это не решило проблему.

       URL hukd = new URL(requestUrl);
        URLConnection tc = hukd.openConnection();
        BufferedReader in = new BufferedReader(new InputStreamReader(tc.getInputStream(), "UTF-8"));
        String line = in.readLine();
        Log.d("line :", line);
        JSONObject obj = new JSONObject(line);
        JSONArray ja = obj.getJSONObject("deals").getJSONArray("items");
        for (int i = 0; i < ja.length(); i++) { // each deal
            JSONObject jo = (JSONObject) ja.get(i);
            // make the deal
            Deal d = new Deal(jo.getString("title"),
                    jo.getString("description"),
                    jo.getString("price"),jo.getString("temperature"), 
                    jo.getJSONObject("merchant").getString("name"),
                    jo.getString("deal_image"),
                    jo.getString("deal_image_highres"));
            listItems.add(d);
            Log.d("Deal:", d.toString());
        }

Log.d "линия" дает

Попробуйте следующий фрагмент кода, который помог мне, когда у меня возникла похожая проблема:

new String(jo.getString("name").getBytes("ISO-8859-1"), "UTF-8");

Я знаю, что это будет через пару лет, но я нашел более надежное решение, чем это, и ему не нужно все дополнительное кодирование

Это было найденоСлучайно, пока я искал что-то еще, но это работает:

"" + jo.opt("name");

То, что это делает, это получает результат как необработанный объект, и помещая его в конец пустой строки, вынуждает его в строковом формате -конечно, если запись изначально не была строкой, она может дать неясные результаты, поэтому, возможно, попробуйте сначала захватить ее как строку

У меня есть что-то вроде этого:

String s = "";
try {
    s = jo.getString("name");
    s = "" + jo.opt("name");
} catch (Exception e) {
    Log.e("JSON error", "error:" + e.toString());
}

Это будетпроверить строку существует, а затем заменить ее на полностью закодированную версию

Я надеюсь, что это поможет кому-то в будущем: -)
