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获取其数据。我正在将JSON数据的项存储为字符串，这会导致出现一些奇怪的字符（例如''）。我明白这与字符集有关，因此我将InputStreamReader设置为“UTF-8”，但似乎没有解决问题。Android JSON CharSet UTF-8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 “行” 给出

任何想法？

你是否也试过其他编码，如“ISO-8859-1”？我用这个解决了一些问题......但它是用于重音字母......哪些字符给你这个问题？ – thermz 2012-01-30 19:52:43

然后Log.d（“line：”，line）的输出到底是什么？ – Jens 2012-01-30 19:53:46

抱歉忘了把日志输出（谢谢Jens）。 – bencallis 2012-01-30 19:58:20

试试下面的代码片段时，我有一个类似的问题这让我：

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

非常感谢。这工作！ – bencallis 2012-01-30 22:15:57

为什么我们必须使用这种扭曲的功能？它必须包含在try catch块中。 – 2013-07-31 13:43:02

我个人喜欢把我所有的json解析放在try catch块中以防万一。 – vm204 2013-07-31 15:52:19

我知道这是一个几年后，但我已经想出比这更可靠的解决方案之一，它并不需要所有的编码额外的东西

这是偶然发现的，而我一直在寻找别的东西，但它的工作原理：

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

这样做我什么将结果作为原始对象获得，并将其放在空字符串的末尾将其强制为字符串格式 - 当然，如果条目最初不是字符串，它可能会给出难以理解的结果，因此可能尝试将其作为串第一

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()); 
}

这将测试该字符串存在，然后用完全编码版本

我希望这可以帮助别人，将来:-)更换
