<div class =“post-text”itemprop =“text”> <P> 你必须使用JSONParser类。它将有助于从webBrowser获取json值。之后你可以像这样使用： </p> <pre> <code> JSONObjcet object=getJSONObject("result"); JSONArray arr=object.getJSONArray("employees"); for(int i=0;i<arr.length;i++){ JSONObject obj1=arr.getJSONObject(i); String firstName=obj1.getString("firstName"); String lastName=obj1.getString("lastName"); } </code> </pre> <P> 我希望这个对你有所帮助:) </p> </DIV>

<div class =“post-text”itemprop =“text”> <P> 这是一个如何使用Volley.jar（lib）来解析JSON的示例。 </p> <pre> <code> private void makeJsonArrayRequest() { showpDialog(); JsonArrayRequest req = new JsonArrayRequest(urlJsonArry, new Response.Listener<JSONArray>() { @Override public void onResponse(JSONArray response) { Log.d(TAG, response.toString()); try { // Parsing json array response // loop through each json object jsonResponse = ""; for (int i = 0; i < response.length(); i++) { JSONObject person = (JSONObject) response .get(i); String name = person.getString("name"); String email = person.getString("email"); JSONObject phone = person .getJSONObject("phone"); String home = phone.getString("home"); String mobile = phone.getString("mobile"); jsonResponse += "Name: " + name + "\n\n"; jsonResponse += "Email: " + email + "\n\n"; jsonResponse += "Home: " + home + "\n\n"; jsonResponse += "Mobile: " + mobile + "\n\n\n"; } txtResponse.setText(jsonResponse); } catch (JSONException e) { e.printStackTrace(); Toast.makeText(getApplicationContext(), "Error: " + e.getMessage(), Toast.LENGTH_LONG).show(); } hidepDialog(); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { VolleyLog.d(TAG, "Error: " + error.getMessage()); Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_SHORT).show(); hidepDialog(); } }); // Adding request to request queue AppController.getInstance().addToRequestQueue(req); </code> </pre> <P> } </p> <P> 来自： <a href="http://www.androidhive.info/2014/09/android-json-parsing-using-volley/" rel="nofollow"> 链接 </A> </p> </DIV>
