Answer 1

使用此

JSONObject json = new JSONObject(jsonstring); 
json.getString("name"); 
.... 

Answer 2

Java有它自己的JSON库，虽然我更喜欢哪个更OO面向谷歌GSON：Google GSON

Answer 3

{ // json object node 
    "SrchResults": [ // jsona array 
     { 
      "FeatCount": "53" 
     }, 
     {    // json object node 
      "NAME": "Dengue_Cluster", // string 
      "Number of cases": "10", 
      "HYPERLINK": "http://www.dengue.gov.sg/cms/ehd/20131647.jpg ", 
      "DESCRIPTION": "Ang Mo Kio Ave 3 (Blk 126, 127, 128)/Ang Mo Kio Ave 6 (Blk 124, 125)", 
      "MAPTIP": "Dengue_Cluster", 
      "SYMBOLCOLOR": "#E600A9", 
      "XY": "29342.6037999997,39300.7427999992" 
     }, 
     {

 try 
     { 
      JSONObject jObj = new JSONObject("My Json string"); 
      JSONArray jr = jObj.getJSONArray("SrchResults"); 
      JSONObject json = (JSONObject) jr.get(0); 
      String key = json.getString("FeatCount"); 
      Log.i("...........",key); 
      for(int i=1;i<jr.length();i++) 
      { 
       JSONObject jb= jr.getJSONObject(i); 
       String name = jb.getString("NAME"); 
       String nofcase = jb.getString("Number of cases"); 
       Log.i("Name is....",name); 
       Log.i("No of cases .........",nofcase); 

      } 
      }catch(Exception e) 
     { 
      e.printStackTrace();
