Your code is almost fine. You just missed one thing. You did not initialize VolleyRequest. Inside simponData and UpdateData methods write this line at the bottom.
RequestQueue requestQueue = Volley.newRequestQueue(getContext());
requestQueue.add(my_request);
instead of AppController.getInstance().addToRequestQueue(updateReq).
other thing is you are calling the fragment in intent from when response is received .You should call onbackPress() when result is recieved successfully.
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
pd.cancel();
try {
JSONObject res = new JSONObject(response);
Toast.makeText(InsertKategori.this, ""+ res.getString("message") , Toast.LENGTH_SHORT).show();
} catch (JSONException e) {
e.printStackTrace();
}
onBackPressed();
}
},
It will restore the previous fragment. In order to update the KategoriFragment view when successful response is received, you can call the getData() method in onResume() method instead of oncreate(). it will call this method whenever fragment is visible to the use

i used spinner and select value and submit it but no error with submission description in database. i am using oracle web services with wamp server, but description submitting spinner value is not.
thanks in advance
use staticSpinner.getSelectedItem().toString() instead of staticSpinner.toString() in posting parameters
you are posting wrong data check below code
insert.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String DESCR = Descr.getText().toString();
final String Spin = staticSpinner.getSelectedItem().toString();
StringRequest request = new StringRequest(Request.Method.POST, insertUrl, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if(Descr.getText().toString().equals("")){
Toast.makeText(getApplication(),"Please Enter Detail ",Toast.LENGTH_LONG).show();
}
else if(Descr.getText().toString().length()<10){
Toast.makeText(getApplication(),"Text Must be Greater Than 10",Toast.LENGTH_LONG).show();

}
public class AttemptLogin extends AsyncTask
{

String email = param[2];
String password = param[1];
String uname= param[0];
ArrayList params = new ArrayList();
params.add(new BasicNameValuePair("username", uname));

JSONObject json = jsonParser.makeHttpRequest(URL, "POST", params);
return json;

} else {
Toast.makeText(getApplicationContext(), "Unable to retrieve any data from server", Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
Now I get an error, like
Error:(250, 12) error: LoginActivity.AttemptLogin is not abstract and does not override abstract method doInBackground(Object...) in AsyncTask
Replace:
extends AsyncTask
with:
extends AsyncTask<String, Void, JSONObject>
Note that the use of AsyncTask is covered in any modern book or course on Android app development.
Here's the AsyncTask Flow Diagram:
I am having trouble trying to get my andoid app to return a list view of all search results returned from a PHP files. I am using a wamp server to host the php files then I call them in the application using Volley. My problem is I can't get it to work with multiple return values. I have tried many different ways using videos online and resources from this site but i cant seem to get to work. This is my first Android application so I am new enough of the idea of a list view and json.

This is the home screen. When a textview is clicked it would launch a request using volley in a seperate request class it is supposed to then return values add them to a json response opject and pass them into the Browse Lost class where it is then added to a listView.
This is the Request class:
package com.example.mullally.newloginregister;
import com.android.volley.Request;
import com.android.volley.Response;
import com.android.volley.toolbox.StringRequest;
import java.util.HashMap;
import java.util.Map;
/**
* Created by mullally on 14/04/2016.
*/
public class BrowseRequest extends StringRequest {
//192.168.11.2
private static final String BROWSE_REQUEST_URL = "http://192.168.11.5/android_content/GetAdvert.php";
private Map<String,String> params;
public BrowseRequest(String status, Response.Listener<String> listener){
super(Request.Method.POST, BROWSE_REQUEST_URL,listener, null);
params=new HashMap<>();
params.put("status", status);
}
#Override
public Map<String, String> getParams() {
return params;
}
}
And this is the activity that is launched to display the list :
package com.example.mullally.newloginregister;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.ArrayAdapter;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.List;
public class BrowseLost extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_browse_lost);
final ListView listView = (ListView) findViewById(R.id.listView);
final Intent intent= getIntent();
String title = intent.getStringExtra("title");
String location = intent.getStringExtra("location");
String details = title + " Location: " + location;
List<String> foundArray = new ArrayList<>();
foundArray.add(details);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_activated_2, android.R.id.text1, foundArray);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// ListView Clicked item index
int itemPosition = position;
// ListView Clicked item value
String itemValue = (String) listView.getItemAtPosition(position);
// Show Alert
Toast.makeText(getApplicationContext(),
"Position :" + itemPosition + " ListItem : " + itemValue, Toast.LENGTH_LONG)
.show();
}
});
}
}
So basically I am trying to populate the listview with all values returned from the PHP. The php encodes the values into a json response eg.
[{"title":"Phone Found","location":"Dublin 6"},{"title":"test","location":"Dublin"},{"title":"dog","location":"Dublin 1"},{"title":"new","location":"Dublin 6W"}]
I am using com.paypal.android.MEP.PayPalActivity library. I want to edit layout but I can't access it. How can I edit default layout of this library. I am trying to transfer money from an account to another account. It works correctly but user interface seems bad

This checkout page layout is default and there is no way you can edit the layout.
