android传字符串给PHP，可是PHP为什么解析出来是乱码

Question

ArrayList nameValuePairs = new ArrayList();
  nameValuePairs.add(new BasicNameValuePair("tb",tb_tbname));
    nameValuePairs.add(new BasicNameValuePair("field",sdfield));
nameValuePairs.add(new BasicNameValuePair("value",sdvalue));
    //http post
    try{
         HttpClient httpclient = new DefaultHttpClient();
         HttpPost httppost = new HttpPost("http://219.229.167.60/ljsql/"+op+".php");
         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
         HttpResponse response = httpclient.execute(httppost);
         HttpEntity entity = response.getEntity();
         is = entity.getContent();
    }catch(Exception e){
         Log.e("log_tag", "Error in http connection"+e.toString());
    }
  //convert response to string
    try{
         BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
         sb = new StringBuilder();
         sb.append(reader.readLine() + "\n");
 
         String line=null;
         while ((line = reader.readLine()) != null) {
              sb.append(line + "\n");
         }
         is.close();
         result=sb.toString();
    }catch(Exception e){
         Log.e("log_tag", "Error converting result "+e.toString());
    }
    //paring data
    
    try{
         jArray = new JSONArray(result);
    }catch(JSONException e1){
         //   Toast.makeText(getBaseContext(), "No City Found" ,Toast.LENGTH_LONG).show();
    } catch (ParseException e1) {
         e1.printStackTrace();
    }
    return jArray;为什么我PHP解析出来变成\u001a\u001a

Answer 1

BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
改为
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"GB2312"),8);

Answer 2

还是乱码，我PHP的编码是UTF-8的

Answer 3

BufferedReader reader = new BufferedReader(new InputStreamReader(is,"UTF-8"),8);
我改成这样，他还是出现乱码

Answer 4

那就改为
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"UTF-8"),8);
如果还乱码，建议检查PHP网页输出后的内容，通过查看浏览PHP网页后的网页源代码判断。

Answer 5

这句
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
也要改为
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, "utf-8"));

Answer 6

我吧PHP传入的值打印出来他变成了\u001a\u001a
