Android : take Data in ListView

Actually in my project, I'm blocked. So, for the first time I ask the community of Stackoverflow. I'm new in development.
So, I have a MySql with my datas and I wan't to see in my application the items of users.
For that, I've this :
public class SuccessActivity extends AppCompatActivity {
public static final int CONNECTION_TIMEOUT = 10000;
public static final int READ_TIMEOUT = 15000;
private ListView listView;
protected String meubles[] = new String[100];
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_success);
Intent intent = getIntent();
String id = intent.getStringExtra("id");
this.listView = (ListView) findViewById(R.id.liste);
new SuccessActivity.Recup().execute(id);
}
//PRIVATE CLASSE POUR AFFICHER LES MEUBLES
private class Recup extends AsyncTask<String, String, String> {
HttpURLConnection conn;
URL url = null;
#Override
protected String doInBackground(String... params) {
try {
//url d'ou reside mon fichier php
url = new URL("http://opix-dev.fr/mytinyhomme/personne/afficher.meuble.php");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return "exception";
}
try {
// parametrage du HttpURLConnection pour recevoir et envoyer des donner à mysql
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(READ_TIMEOUT);
conn.setConnectTimeout(CONNECTION_TIMEOUT);
conn.setRequestMethod("POST");
// setDoInput and setDoOutput method depict handling of both send and receive
conn.setDoInput(true);
conn.setDoOutput(true);
// Append parameters to URL
Uri.Builder builder = new Uri.Builder()
.appendQueryParameter("id", params[0]);
String query = builder.build().getEncodedQuery();
// Open connection for sending data
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(query);
writer.flush();
writer.close();
os.close();
conn.connect();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
return "exception";
}
try {
int response_code = conn.getResponseCode();
// Check if successful connection made
if (response_code == HttpURLConnection.HTTP_OK) {
// Read data sent from server
InputStream input = conn.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(input));
StringBuilder result = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
result.append(line);
}
// Pass data to onPostExecute method
return (result.toString());
} else {
return ("unsuccessful");
}
} catch (IOException e) {
e.printStackTrace();
return "exception";
} finally {
conn.disconnect();
}
}
#Override
protected void onPostExecute(String resulta) {
//this method will be running on UI thread
if (resulta.equalsIgnoreCase("false")) {
} else if (resulta.equalsIgnoreCase("exception") || resulta.equalsIgnoreCase("unsuccessful")) {
} else {
try {
JSONArray nom = new JSONArray(resulta);
System.out.println(nom);
String meubles[] = new String[100];
for (int i = 0; i < nom.length(); i++){
JSONObject jsonobject = nom.getJSONObject(i);
meubles[i]= jsonobject.getString("nom");
System.out.println(jsonobject);
System.out.println(meubles);
item.setText( meubles[i]);
}
System.out.println(meubles);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
}
The file.php is correct because the JSONArray in System.print is ok But I've try with some TextView for display the board at the end, but I did not succeed.
How I can use the meuble[0] , meuble[1], meuble[2](it's board of String name of items) in a ListView ?

Here is what you need to do to show your data in a listview,
Modified onPostExecute() method:
#Override
protected void onPostExecute(String resulta) {
//this method will be running on UI thread
if (resulta.equalsIgnoreCase("false")) {
} else if (resulta.equalsIgnoreCase("exception") || resulta.equalsIgnoreCase("unsuccessful")) {
} else {
try {
JSONArray nom = new JSONArray(resulta);
System.out.println(nom);
String meubles[] = new String[100];
for (int i = 0; i < nom.length(); i++){
JSONObject jsonobject = nom.getJSONObject(i);
meubles[i]= jsonobject.getString("nom");
System.out.println(jsonobject);
System.out.println(meubles);
}
ArrayAdapter<String> listAdapter=new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,meubles);
listView.setAdapter(listAdapter);
System.out.println(meubles);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
What's added?
You need an adapter to show items in a listview. You can create your custom adapter class by extending an arrayadapter or you can use an arrayadapter without customizing it as shown.
Added code:
Create a new adapter,
ArrayAdapter listAdapter=new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,list);
Set adapter for your listview,
listView.setAdapter(listAdapter);

Android going to 'else' even when result matches the if statement

I am developing an android app.
In a specific part of my code, the else option is always executed, even though the if statement is satisfied. Any help is highly appreciated.
Here is my code:
PHP:
<?php
error_reporting(0);
include 'conexao.php';
$usuario = $_POST["username"];
$senha = $_POST["password"];
$result = mysql_query("select * from login where usuario = '" . $usuario . "' and senha = '" . $senha . "';");
$num_rows = mysql_num_rows($result);
if ($num_rows == 0) {
echo 'false';
} else if ($num_rows == 1) {
echo 'true';
} else {
echo 'nenhum';
}
?>
and my Java :
EditText txtusuario, txtsenha;
Button btnlogin;
public static final int CONNECTION_TIMEOUT=10000;
public static final int READ_TIMEOUT=15000;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
txtusuario = (EditText) findViewById(R.id.txtusuario);
txtsenha = (EditText) findViewById(R.id.txtsenha);
btnlogin = (Button) findViewById(R.id.btnlogin);
btnlogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Get text from email and passord field
final String username = txtusuario.getText().toString();
final String password = txtsenha.getText().toString();
// Initialize AsyncLogin() class with email and password
new AsyncLogin().execute(username,password);
}
});
}
private class AsyncLogin extends AsyncTask<String, String, String>
{
ProgressDialog pdLoading = new ProgressDialog(LoginActivity.this);
HttpURLConnection conn;
URL url = null;
#Override

super.onPreExecute();
//this method will be running on UI thread

NotificationManager mNot = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNot.notify(a, mBuilder.build());
}
}
}
the result in my notification is 'deu errado true' when true should been the if statement, and I have already tried result.equals("true")

if ($num_rows == 0) {
echo 'false';
} else if ($num_rows == 1) {
echo 'true';
} else {
echo 'nenhum';
}
instead of this make sure your code should be just like
if ($num_rows) {
echo 'false';
} else {
echo 'nenhum';
}

#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
//this method will be running on UI thread
pdLoading.dismiss();
String teste = "true";
int a = 0;
NotificationCompat.Builder mBuilder = new
NotificationCompat.Builder(LoginActivity.this);
mBuilder.setSmallIcon(R.drawable.escavadeira);
mBuilder.setContentTitle("Notificação");
if (result.equals(teste)) {
//Notificação para saber o resultado do login
mBuilder.setContentText("Conexão deu certo caralho" + result);
} else {
mBuilder.setContentText("Deu errado" + result);
}
NotificationManager mNot = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNot.notify(a, mBuilder.build());

Get unique item id from item list in Android

I was creating android project in that i am using itemlist view and pagination . while clicking on that particular item i want to get that item id.but i am not getting the unique id.

If you are keeping count of page then you can add page number to item position.
That will give you unique number for each item.

d How can I use progress bar while fetching data from database?

I'm really bad at googling things I want so I decided to ask here. My question is is it possible to show a progress bar while fetching the data from the database? I'm using the typical code when fetching data(Pass value to php and the php will do the query and pass it again to android)
Edit(I have tried adding proggressdialog but the problem now is the loaded data will appear first before the progress dialog here's my AsyncTask code)
public class getClass extends AsyncTask<String, Void, String> {

Have you tried using an AsyncTask?
You can show your progress bar on the preExecute method and then hide it on postExecute. You can do your querying inside the doInBackground method.

In addition to what #torque203 pointed, I would suggest you to check
http://developer.android.com/reference/android/os/AsyncTask.html#onProgressUpdate(Progress...)
this method was created for that purpose, showing progress to the user.

From developers docs:
private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
#Override
protected void onPreExecute() {
//show progress bar here
}
protected Long doInBackground(URL... urls) {
//Pass value to PHP here
//get values from your PHP
}
protected void onPostExecute(Long result) {
//Here you are ready with your PHP value. Dismiss progress bar here.
}
}

public void onPreExecute() {
Progress Dialog pDialog = new ProgressDialog(this);
pDialog.setMessage("Loading...");
pDialog.show();
}
public void doInBackground() {
//do your JSON Coding
}
public void onPostExecute() {
Progress Dialog pDialog = new ProgressDialog(this);
pDialog.setMessage("Loading...");
pDialog.show();
}

how to post using HttpUrlConnection in android -> getting error : java.io.IOException: content-length promised 82 bytes, but received 43

Hello here I am trying for the post data from android to server.I am trying using HttpURLConnection.
Here I am sending username & password for Authentication for entering data for particular user in drupal. I have also tried to post data with various other methods. Using DefaultHttpClient but no luck. I am getting 401 error with using DefaultHttpClient.
Here is the link of question that I have asked on stackoverflow. Authentication error: Unable to respond to any of these challenges: {} Android - 401 Unauthorized
SO please help. Thanks for listening.

Thanks.

You set the content length here:
httpcon.setRequestProperty("Content-Length", "" + Integer.toString(urlParameters.getBytes().length));
But the content you sent comes from here:
byte[] outputBytes = "{\"username\":\"uname\",\"password\":\"pass\"}".getBytes("UTF-8");
OutputStream os = httpcon.getOutputStream();
os.write(outputBytes);
So the reported Content-Length does not match the actual content length.
Ignore the httpcon.connect(); in the middle, it does nothing because you are already connected.
Instead, you need to do:
byte[] outputBytes = "{\"username\":\"uname\",\"password\":\"pass\"}".getBytes("UTF-8");
httpcon.setRequestProperty("Content-Length", Integer.toString(outputBytes.length()));
OutputStream os = httpcon.getOutputStream();
os.write(outputBytes);
