Problemy z Androidem JSON CharSet UTF-8

Question

Aktualnie pracuję nad aplikacją na Androida, która pobiera dane z interfejsu API, który dostarcza dane JSON. Przechowuję elementy dla danych JSON jako ciągi znaków, co powoduje pojawienie się nieparzystego znaku (np. "Â"). Rozumiem, że ma to związek ze zbiorem znaków, dlatego ustawiłem InputStreamReader na "UTF-8", ale wydaje się, że nie rozwiązało to problemu.

 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()); 
     } 

"linia" Log.d daje

Jakieś pomysły?

Answer 1

Wypróbuj poniższy fragment kodu, który pomógł mi gdy miałem podobny problem:

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

Answer 2

wiem, że to kilka lat później, ale muszę wymyślić bardziej niezawodne rozwiązanie niż to jeden, i nie trzeba cały kodowania dodatkowych rzeczy

ten został znaleziony przez przypadek podczas gdy szukałem czegoś innego, ale to działa:

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

Co to ja s uzyskują wynik jako surowy obiekt, a umieszczenie go na końcu pustego łańcucha wymusza na format ciągu - oczywiście, jeśli pozycja nie była oryginalnie ciągiem, może dać niejasne wyniki, więc może spróbuj zgarnąć ją jako pierwszy ciąg

mam coś takiego:

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

to będzie przetestować ciąg istnieje, a następnie zastąpienie go całkowicie zakodowany wersji

mam nadzieję, że to pomoże komuś w przyszłości :-)
