OnItemSelectedListener kept changing to adapter view

I want to create a spinner that retrieve data from database but OnItemSelectedListener won't work. It keeps suggesting to adapterview.OnclickListener but the coding need OnClickListenerOnly.

follow this code-
spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
String msupplier=supplier.getSelectedItem().toString();
Log.e("Selected item : ",msupplier);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});

I used same answered by sud but with little modification which worked
spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
// TODO Auto-generated method stub
// String msupplier=supplier.getSelectedItem().toString(); instead used below
Log.e("Selected item : ", (String) parent.getItemAtPosition(pos));
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub
}
});

Two activities sending data to each other

Two activities are sending data to each other.
The first activity has a custom list view. The second has one text view and three buttons to increase and decrease a value.
When I click on the first activity, the second activity opens. The second activity increases the text view value and clicked the button. Data goes to the first activity. Same process again.
My problem is that the total value is not displayed in the first activity.
How can i show all increase and decrease values from the second activity in the first activity?

*edit> I think the problem is that the listview is empty, i dont really know where the problem is

because the UI thread is Blocked
Rather than using your thread class use Asynctask
class xyz extends Asynctask
{
}
then add to overrididen methods
do in background
on post execute

can anyone help me ???
the error is in the jsonActivityHttpClient class in the onPostExectute method, it do not take the list "finalResult" neither:

i see 2 problem in your code:
1- you define your AsyncTask class like
AsyncTask<Void, Void, List<String>>
but you get Void on onPostExecute method, so you need change
protected void onPostExecute(Void result)
to
protected void onPostExecute(List<String> result)
2- you try access to finalResult on onPostExecute, bu you define that as static on JSONParserHandler so if you want access that you need :
JSONParserHandler.finalResult
but as you return that on doInBackground method so you can access that with:
result
that you get in onPostExecute.
then you need check result that is equal to null or not, because you return null after catch
your onPostExecute must be like:
protected void onPostExecute(List<String> result) {
// TODO Auto-generated method stub
if (null != mClient) {
mClient.close();
if (result != null)
{
ListAdapter adapter = new SimpleAdapter(
JsonActivityHttpClient.this, result,
R.layout.list_item, new String[] { PLACE_NAME_TAG, LATITUDE_TAG,
LONGITUDE_TAG, POSTAL_CODE_TAG }, new int[] { R.id.countryname,
R.id.lat, R.id.lng, R.id.postalcode });
setListAdapter(adapter);
}
else
// do any thing you want for error happened
}

How do i get this in asynctask

i got my app working so it returns the information from a json api.
now i realize that i have to put everything in a asynch task so it doesn't crash as much
and a progress dialog is easier, only i really don't know how to do this so im wondering if somebody knows a really good tutorial or wants to edit my code a bit to get my started

There is good class AsyncTask to do something Asyncronius in Android.
Example:
private class DownloadFilesTask extends AsyncTask
{
protected Long doInBackground(URL... urls) {
int count = urls.length;
long totalSize = 0;
for (int i = 0; i < count; i++) {
totalSize += Downloader.downloadFile(urls[i]);
publishProgress((int) ((i / (float) count) * 100));
}
return totalSize;
}
protected void onProgressUpdate(Integer... progress) {
setProgressPercent(progress[0]);
}
protected void onPostExecute(Long result) {
showDialog("Downloaded " + result + " bytes");
} }
