Android JSON CharSet UTF-8问题

我目前正在开发一个Android应用程序,它从提供JSON数据的API获取数据。 我将JSON数据的项目存储为字符串,这会导致出现一些奇怪的字符(例如’Â’)。 我理解这与字符集有关,因此我将InputStreamReader设置为“UTF-8”,但它似乎没有解决问题。

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“line”给出

有任何想法吗?

尝试下面的代码片段,当我遇到类似的问题时帮助了我:

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

我知道这是几年之后,但我提出了一个比这个更可靠的解决方案,它不需要所有的编码额外的东西

这是偶然发现的,当时我正在寻找别的东西,但它有效:

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

这样做是将结果作为原始对象,并将其放在空字符串的末尾强制它成为字符串格式 – 当然,如果条目原来不是字符串,它可以给出模糊的结果,所以也许尝试抓取它首先是一个字符串

我有这样的事情:

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

这将测试字符串是否存在,然后将其替换为完全编码的版本

我希望这可以帮助将来的某个人:-)
