}*/
/* Uri.Builder b = Uri.parse(AppConfig.URL_JSON_PRODUCT_NEW).buildUpon(); //this didn't work either
b.appendQueryParameter("matGroup", "FG0001");
String url = b.build().toString();*/
when i am using StringRequest the String is parse to the pHp.I can't use StringRequest because i want to get a jsonObject
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, AppConfig.URL_JSON_PRODUCT, null, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
productList = parseJsonResponse(response);
pAdapter.setProductList(productList);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}) {
@Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put("matGroup", "FG0001");
return hashMap;
}
};
requestQueue.add(request);
}
this is my php file. the string that parsing from the getParams should assign to the $matGroup
<?php
require_once 'include/Config.php';
//header('Content-Type: application/json');
$con = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) or die("connection failed");
mysql_select_db(DB_DATABASE,$con) or die("db selection failed");
//if(isset($_POST['matGroup']))
$matGroup = $_GET['matGroup'];
$r=mysql_query("select tbl_inventory.*,tbl_mas_material.des,tbl_mas_material.matgrp from tbl_inventory INNER JOIN tbl_mas_material on tbl_inventory.material=tbl_mas_material.material where tbl_inventory.qty>'0' and matgrp = '$matGroup'");
$result = array();
while($row=mysql_fetch_array($r)){
array_push($result,
array('material'=>$row[0],
'plant'=>$row[1],'qty'=>$row[3],'ton'=>$row[4],'val'=>$row[5],'des'=>$row[6],'matgrp'=>$row[7]));}
echo json_encode(array("feed"=>$result));
mysql_close($con);
?>
You have to use CustomJSONRequestas the getParams() doesn't invoke because JsonObjectRequest extended JsonRequest which invoke getBody() directly to encoding the constructor second parameter(call requestBody) as contentType, that's why it ignore your getParam() method.
public class CustomRequest extends Request<JSONObject> {
private Listener<JSONObject> listener;
private Map<String, String> params;
public CustomRequest(String url, Map<String, String> params,
Listener<JSONObject> reponseListener, ErrorListener errorListener) {
super(Method.GET, url, errorListener);
this.listener = reponseListener;
this.params = params;
}
public CustomRequest(int method, String url, Map<String, String> params,
Listener<JSONObject> reponseListener, ErrorListener errorListener) {
super(method, url, errorListener);
this.listener = reponseListener;
this.params = params;
}
protected Map<String, String> getParams()
throws com.android.volley.AuthFailureError {
return params;
};
@Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {
try {
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
return Response.success(new JSONObject(jsonString),
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JSONException je) {
return Response.error(new ParseError(je));
}
}
@Override
protected void deliverResponse(JSONObject response) {
// TODO Auto-generated method stub
listener.onResponse(response);
}
}
And you will call the Custom Request as
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
CustomRequest jsObjRequest = new CustomRequest(Method.POST, url, params, this.createRequestSuccessListener(), this.createRequestErrorListener());
requestQueue.add(jsObjRequest);

Hope this helps.
UPDATE
StringRequest request = new StringRequest(Request.Method.POST,
AppUrls.URL_SAVE_DATA, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject json = new JSONObject(response);
String status = "";
if(json != null && json.has(JSONParsor.STATUS))
status = json.getString(JSONParsor.STATUS);
if(status != null && status.length() > 0 && status.equalsIgnoreCase("success")) { }
} catch (JSONException e) {
Log.d("JSON Exception", e.toString());
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
if(error == null) {
}
}
})
{
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put(KEY_PICTURE_NAME, picture.getFileName());
params.put(KEY_SECTION_ID, picture.getSectionId() + "");
return params;
}
};
request.setTag(SAVE_DATA);
addToRequestQueue(request);
Hope this helps
