I'm currently working on a Account Management Activity for my Android application and I'm having trouble figuring out why the setSelection() method from a spinner does not trigger the OnItemSelectedListener attached to said Spinner.
Here is what I have currently;
onCreate() method :
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.account_management);
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
retreiveLanguage();
initializeUI();
// Vérification si l'usager est déjà connecté
Globals appState = ((Globals) this.getApplication());
boolean userLoggedIn = appState.isUserLoggedIn();
boolean userInfoAvailable = appState.isUserInfoAvailable();
if (userLoggedIn && userInfoAvailable) {
fillUI();
}
}
Pertinent lines from the initializeUI() method which is called on the Activity's creation which shows the binding of the Spinner the Listener :
/** OnItemSelectedHandler for the Country Spinner */
mCountrySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view,
int pos, long id) {
Log.i(TAG, "onCountrySelected() was called, position : " + pos);
mProvinces = new ArrayList<String>();
mProvincesCode = new ArrayList<String>();
mXML.parseResponse(FileManager.getInstance().getPortalOptions());
for (int i = 0; i < mXML.getCountry(pos).sizeProvinces(); i++){
mProvinces.add(mXML.getCountry(pos).getProvince(i).getLabel(mLanguage));
mProvincesCode.add(mXML.getCountry(pos).getProvince(i).getCode());
}
mProvinceArrayAdapter = new ArrayAdapter<String>(ManageAccountActivity.this,
android.R.layout.simple_spinner_item, mProvinces);
mProvinceArrayAdapter.setDropDownViewResource(
android.R.layout.simple_spinner_dropdown_item);
mProvinceSpinner.setAdapter(mProvinceArrayAdapter);
}
public void onNothingSelected(AdapterView<?> arg0) {
// Do Nothing ...
}
});
And again another couple lines, this time from the fillUI method() :
Log.i(TAG, "Setting country based on user information.");
((Spinner) findViewById(R.id.spin_country))
.setSelection(mCountriesCode.indexOf(mUser.getCountry()));
// TODO : Fix Provinces and States not being changed accordingly
Log.i(TAG, "Setting province based on user information.");
((Spinner) findViewById(R.id.spin_province))
.setSelection(mProvincesCode.indexOf(mUser.getProvince()));
So with this I would expect the OnItemSelectedListener to be called right after I set the selection in the fillUI() method, but that's not what's happening at runtime :S
Here's my LogCat extract that shows that the Listener isn't called when the selection is applied to the country spinner:
I/ManageAccountActivity(28108): Setting country based on user information.
I/ManageAccountActivity(28108): Setting province based on user information.
I/ManageAccountActivity(28108): onCountrySelected() was called, position : 1
As an experiment, I also tried putting the fillUI() call in the onStart method of my Activity but that didn't change how the application reacted.
Thanks in advance for any pointers, help or tips !
Have you tried to set the spinner by using two arguments, the second using a boolean:
.setSelection(mProvincesCode.indexOf(mUser.getProvince()), true);
From the developers page it shows:
setSelection(int position, boolean animate)
//Jump directly to a specific item in the adapter data.
