        e.printStackTrace();
    }
//...
os.println(jsonObject.toString());
RECEIVE JSON
JSONTokener jsonTokener=new JSONTokener(str);
JSONObject jsonObject1=(JSONObject)jsonTokener.nextValue();
String phone=jsonObject1.getString("Phone");
String name=jsonObject1.getString("Name");

遍历JsonObject

Iterator<String> ls = object.keys();while(ls.hasNext()){
    String a = ls.next();}

解析JsonArray
JSONTokener jsonTokener=new JSONTokener("[{\"Name\":\"steven\"},{\"Name\":\"kk\"}]");try {
    JSONArray jsonArray=(JSONArray)jsonTokener.nextValue();    
textView.setText(jsonArray.getJSONObject(1).getString("Name"));

JSONTokener jsonTokener=new JSONTokener("[{\"Name\":\"steven\"},{\"Name\":\"kk\"}]");try {
    JSONArray jsonArray=(JSONArray)jsonTokener.nextValue();    textView.setText(jsonArray.getJSONObject(1).getString("Name"));} catch (JSONException e) {
    Toast.makeText(this,e.toString(),Toast.LENGTH_LONG).show();}
