Problèmes Android JSON CharSet UTF-8
Je suis actuellement en train de travailler sur une application Android, qui obtient ses données à partir d'une API qui fournit des données JSON.
Je suis le stockage des éléments de données JSON comme des Chaînes de caractères qui donne lieu à de drôles de caractères apparaissant (par exemple, 'Â'). Je comprends ce qu'il à faire avec le jeu de caractères, donc j'ai mis de l'InputStreamReader "UTF-8" mais il ne semble pas avoir résolu le problème.
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());
}

I nearly blew a fuse when I saw they had been reduced from \u00c2\u00a380.00 to under \u00c2\u00a350 as I just bought 3 of these before xmas at \u00c2\u00a368.00 ea which I thought was a true bargain.\r\n\r\nI asked they guy and he said they were stopping doing them as far as he knew and that the deal should be nation wide this must be the cheapest I've seen for the UK version ever even though this is the Harmony one and not the one + is it still a great remote which does just about everything you could want it to. \r\n\r\n** note I don\u00e2\u0080\u0099t have a picture of the price tag but I have these at my home and are 100% that it\u00e2\u0080\u0099s the harmony one on sale hope this helps some of you guys and girls out **\r\n\r\nThe Logitech Harmony One remote control lets you replace 15 remotes with one, easy to use device. With its clear, touch screen display this Harmony learning remote control makes controlling the most complex of systems easy. A graphic interface allows you, for example, to watch a DVD at the touch of a button.\r\n","submit_time":"48 minutes ago","hot_time":"1 minute ago","poster_name":"no1son","temperature":106.88999939,"price":49.98,"timestamp":1327950390,"expired":"false","forum":{"name":"Deals","url_name":"deals"},"category":{"name":"Audiovisual","url_name":"audiovisual"},"merchant":{"name":"Comet","url_name":"comet.co.uk"},"tags":{"items":[{"name":"leeds"}]},"deal_image_highres":"http:\/\/www.hotukdeals.com\/images\/threads\/high-res\/1131779_1.jpg"},{"title":"Youth Brazil Shirt \u00c2\u00a34 at Very\/Littlewoods","deal_link":"http:\/\/www.hotukdeals.com\/deals\/youth-brazil-shirt-4-very-littlewoods-1131765?aui=465","mobile_deal_link":"http:\/\/m.hotukdeals.com\/deals\/youth-brazil-shirt-4-very-littlewoods-1131765?aui=465","deal_image":"http:\/\/www.hotukdeals.com\/images\/threads\/1131765_1.jpg","description":"2010 Brazil shirt by Nike\r\nAvailable in all youth sizes.\r\nFree delivery through collect plus","submit_time":"1 hour, 4 minutes ago","hot_time":"14 minutes ago","poster_name":"ericagradus","temperature":161.479995728,"price":4,"timestamp":1327949447,"expired":"false","forum":{"name":"Deals","url_name":"deals"},"category":{"name":"Fashion","url_name":"fashion"},"merchant":{"name":"Very","url_name":"very.co.uk"},"tags":{"items":[{"name":"brazil shirt"},{"name":"very"},{"name":"littlewoods"}]},"deal_image_highres":"http:\/\/www.hotukdeals.com\/images\/threads\/high-res\/1131765_1.jpg"},{"title":"Milk Chocolate Mikado 29p at Home Bargains","deal_link":"http:\/\/www.hotukdeals.com\/deals\/milk-chocolate-mikado-29p-home-bargains-1130742?aui=465","mobile_deal_link":"http:\/\/m.hotukdeals.com\/deals\/milk-chocolate-mikado-29p-home-bargains-1130742?aui=465","deal_image":"http:\/\/www.hotukdeals.com\/images\/threads\/1130742_1.jpg","description":"Was in Home Bargains in Lancaster and they had the MIlk Chocolate Mikado for 29p.

Essayez l'extrait de code suivant code qui m'a aidé quand j'ai eu un problème similaire:
Je sais que c'est un couple d'années après, mais je suis venu avec une solution fiable que celui-ci, et il n'a pas besoin de l'encodage des trucs supplémentaires
Ce fut trouvé par hasard alors que je cherchais quelque chose d'autre, mais il fonctionne:
Ce que ce n'est obtenir le résultat sous la forme d'un objet brut, et de le mettre à la fin d'une chaîne vide forces dans la chaîne de format - bien sûr, si l'entrée n'était pas à l'origine une chaîne, il peut donner des résultats incohérents, alors peut-être essayer de la saisir comme une chaîne de caractères première
J'ai quelque chose comme ceci:
Ce sera un test de la chaîne existe, et puis le remplacer par le entièrement codé version
J'espère que cela aide quelqu'un dans le futur 🙂
