dynamic spinner consuming rest services creating issue on OnClickListener

I have an android project containing spinner which consumes rest services and is able to get data dynamically
The problem is it gets data when i click the button and not the spinner
I tried setting setOnClickListener function on spinner but it doesn't work
the code is
private Context mContext=HourlyEntry.this;
private Spinner s1;
private String m_DepartmentID=null;
private ArrayList<String> m_Department_list;
private ArrayList<String> m_DepartmentID_list;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hourly_entry);
s1=(Spinner)findViewById(R.id.spinner1);
s1.setOnClickListener(this);
}
#Override
public void onClick(View v) {
if (v == s1)
{
JSONObject login = new JSONObject();
try
{
login.put("EmployeeID","1");
//login.put("Password", etCountry.getText().toString());
JSONObject finaldata = new JSONObject();
finaldata.put("ProjectRequest", login);
final ConnectToServer connect = new ConnectToServer();
connect.extConnectToServer(HourlyEntry.this,
new ConnectToServer.Callback()
{
public void callFinished(String result)
{
//Toast.makeText(getBaseContext(), result,
Toast.LENGTH_LONG).show();
JSONObject resp = null;
try
{
resp = new JSONObject(result);
Toast.makeText(getBaseContext(), result, Toast.LENGTH_LONG).show();
JSONObject Login1Result = resp.getJSONObject("ProjectResult");
JSONArray DepartmentDetails = Login1Result.getJSONArray("ProjectDetails");
//String strMessage = Login1Result.getString("message");
Toast.makeText(getBaseContext(), Login1Result.getString("ProjectDetails"), Toast.LENGTH_LONG).show();
// List<String> list = new ArrayList<String>();
if (!Login1Result.getString("ProjectDetails").equalsIgnoreCase("null"))
{
//JSONArray DepartmentDetails = Login1Result.getJSONArray("ProjectDetails");
m_Department_list = new ArrayList<String>();
m_DepartmentID_list = new ArrayList<String>();
for (int i = 0; i < DepartmentDetails.length(); i++)
{
JSONObject m_DepartmentDetails = DepartmentDetails.getJSONObject(i);
if (!m_DepartmentDetails.getString("ProjectName").equalsIgnoreCase("null")&& !m_DepartmentDetails.getString("ProjectName").equalsIgnoreCase(""))
{
//list.add(m_DepartmentDetails.getString("ProjectName"));
m_Department_list.add(m_DepartmentDetails.getString("ProjectName"));
//Toast.makeText(getBaseContext(), m_DepartmentDetails.getString("ProjectName"), Toast.LENGTH_LONG).show();
}
if (!m_DepartmentDetails.getString("ProjectID").equalsIgnoreCase("null")&& !m_DepartmentDetails.getString("ProjectID").equalsIgnoreCase(""))
{
m_DepartmentID_list.add(m_DepartmentDetails.getString("ProjectID"));
}
}
}
s1 = (Spinner) findViewById(R.id.spinner1);
final ArrayAdapter<String> adapter = new ArrayAdapter<String>(mContext, R.layout.spin,m_Department_list);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s1.setAdapter(adapter);
if (m_DepartmentID_list.contains(m_DepartmentID))
{
s1.setSelection(m_DepartmentID_list.indexOf(m_DepartmentID));
}
}
catch (final JSONException e)
{
}
}
}, "http://aapnapms.azurewebsites.net/Service1/Project", finaldata,
"POST");
connect.execute(finaldata);
if(!validate())
Toast.makeText(getBaseContext(), "Enter some data !", Toast.LENGTH_LONG).show();
}
catch (Exception e) {
Log.d("InputStream", e.getLocalizedMessage());
}
}

Use
s1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
instead of
s1.setOnClickListener(this);

Not getting the correct data on clicking the LISTVIEW

I have 3 list in my fragment i.e. list 1,list2 and list3. And all are interdependent.I'm using AsyncTask for showing these list.
When i click on list 1 its shows some data on list 3 and so on when i clik on list 2 it shows data on list3.
Now the problem is there is a next button,if i don't click on list 2 and press next it does not show the correct data.
list 2 returns null and thus does not functional correct.
Below is the code
public class Browse extends Fragment {

My question is : when I input words in the EditText, nothing happened. But when I press backspace did the AutoCompleteTextView show the suggestion list ... the problem is in the editAuto.setAdapter(adapter);
What is wrong?

make the following changes in your code
1) Instead of
private AutoCompleteTextView editAuto = null; JUST WRITE private AutoCompleteTextView editAuto;
2) Add this line to onCrate()
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, <your array name here>);
and remove this line from onTextChangedTask()
ArrayList<String> userNameArrayList = new ArrayList<String>();
3) Add this line to onCrate()
editAuto.setAdapter(adapter);

I know this is way late but for those who face similar problems here is the solution to show the autoCompleteTextView's drop down whenever you want i.e on button click or onTextChanged. After you set the ArrayAdapter for the autoCompleteTextView just put the following line.
autoCompleteTextView.showDropDown();

android - update progressbar

I would like to update spinner object after I get a google calendar name in a different thread. When I execute this, it crashes. I am not sure if I need to make it work with a different approach or if there is something wrong with it.
private void updateGoogleCalendar() {
try {
Thread.sleep(4000);
List<String> list = new ArrayList<String>();
list.add("Sample Calendar");
updatedCalendarNames = list.toArray(new String[0]);
progressBar.dismiss();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
public void initializeWidgets() {
final Spinner spinner = (Spinner) layout.findViewById(R.id.googleCalendarSelection);
final Button refreshCalendarBtn = (Button) layout.findViewById(R.id.refreshCalendarBtn);
refreshCalendarBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
progressBar = ProgressDialog.show(getContext(), "", "Loading...");
new Thread(new Runnable() {
#Override
public void run() {
updateGoogleCalendar();
final ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(getContext(), android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
while (updatedCalendarNames == null) {
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
for (String calendarName : updatedCalendarNames) {
CharSequence charSequence = calendarName + "";
adapter.add(charSequence);
}
}
}).start();
}
});
}

you need to add your ui update code into event thread only, and to notify UI/Event Thread you need to implement Handler or AsyncTask, for example you can update by handler as follows:
public void initializeWidgets() {
final Spinner spinner = (Spinner) layout.findViewById(R.id.googleCalendarSelection);
final Button refreshCalendarBtn = (Button) layout.findViewById(R.id.refreshCalendarBtn);
refreshCalendarBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
progressBar = ProgressDialog.show(getContext(), "", "Loading...");
new Thread(new Runnable() {
#Override
public void run() {
updateGoogleCalendar();
final ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(getContext(), android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
while (updatedCalendarNames == null) {
try {
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
for (String calendarName : updatedCalendarNames) {
Message msg=handler.obtainMessage();
msg.obj = calendarName + "";
handler.sendMessage(msg);
}
}
}).start();
}
});
}
Handler handler=new Handler()
{
public void handleMessage(Message msg)
{
String str=(String)msg.obj;
adapter.add(charSequence);
}
};

You don't say where it crashes or how, but I imagine it might be due to you trying to update the UI from a non-UI thread. Take a look at the AsyncTask (see here) for information.
