I am trying to populate spinners with data from MySQL (I am having to rows) but they stay empty. Also, those spinners should be dependent on each other. Any ideas why? When I call url in local host it returns right values, so the PHP is working fine(example of one row from PHP: [{"Grad":"Beograd","Predmet":"matematika"}...], I m more worried about putting those rows in a list.
public class IzboraGrada extends Activity {

And PHP code:
$con = mysqli_connect($host, $user, $pwd, $db);
if(mysqli_connect_errno($con)) {
die("Failed to connect to MySQL: " . mysqli_connect_error());
}
$sql = "SELECT Grad, Predmet FROM lista";
$result = mysqli_query($con, $sql);
$rows = array();
while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
$rows[] = $row;
}
mysqli_close($con);
echo json_encode($rows);
you aren't populating your spinners, look to a part of your code ;
ArrayAdapter<String> dataAdapter1 = new ArrayAdapter<String>(getApplicationContext(),
dataAdapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Android is reading it as one line, without valid references to the right data. Please replace it by the following,
// adapter for spinner
ArrayAdapter<String> dataAdapter1 = new ArrayAdapter<String>(getApplicationContext(), $$$, list1);
// set layout
dataAdapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
replace the $$$ to the spinner item-id in your XML layout. Do the same for spinner2

I want to display some data in a listview from database using asynctask.
I want that firstly user inputs some data and on submit button click in doinbackground in asynctask, database checks for result like login something and from there details or response comes from database in the form of array. Now i want that details to be displayed in a listview.
I want the details to be displayed in another activity.

i have created the two spinner in xml namely myspinner and myspinner1. The myspinner value is obtained from the json value.Based on myspinner item selected,we get the hotel id.That retrieved hotel id is used to call the another AsyncT1.In the AsyncT1 the myspinner1 value get listed out.My problem is,if i select the myspinner the myspinner1 value is not updated it remains same.I have tried the adapter.notifydatasetchanged() but till now not updated.`

How can I do this: I have 2 Spinners in my app and one is for Departament and other is for Doctor, when I select one department in Departament spinner I want my second spinner to show only the doctor's who belong to that department. I'm using MYSQL Database to fetching data from two different tables. I populate both table with a urlconection. Here is my code:

sp = (Spinner) view.findViewById(R.id.spinner1);
adapter = new ArrayAdapter<String>(getActivity(), R.layout.spinner1_layout, R.id.txt1, listItems);
sp.setAdapter(adapter);
sp.setFocusable(true);
sp.clearFocus();
sp2 = (Spinner) view.findViewById(R.id.spinner2);
adapter2 = new ArrayAdapter<String>(getActivity(), R.layout.spinner2_layout, R.id.txt2, listItems2);
sp2.setAdapter(adapter2);
sp2.setFocusable(true);
