My android application keeps crashing when I call the dialog containing this spinner, I'm sure my XML is ok
I tried to spot the problem by making the code as a comment and it turns that the problem is with the setAdapter line
Please if anyone can help, it will be so cool.
CountryManager cm = new CountryManager(this);
user = new UserAppManager(this).getUser();
String countries = user.getCountries();
ArrayList<Country> countriesListe = cm.getCountryByCodes(countries);
Spinner countrieSpinner = mDialogStart.findViewById(R.id.sp_countries);
CountriesListAdapter adapter = new CountriesListAdapter(this, R.layout.country_list_item, countriesListe);
countrieSpinner.setAdapter(adapter);
country = user.getDefaultCountry();
int position = adapter.indexOf(country);
Log.w(TAG, "countries::" + countries + "|| country::" + country + " || position::" + position);
countrieSpinner.setSelection(position);
countrieSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int pos, long l) {
country = Objects.requireNonNull(adapter.getItem(pos)).getCode();
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
country = user.getDefaultCountry();
}
code for the adapter list
public class CountriesListAdapter extends ArrayAdapter<Country> {
private final Context context;
//private final String[] values;
private ArrayList<Country> countries;
public CountriesListAdapter(Context context,int ressource,ArrayList<Country> countries) {
super(context, ressource, new CountryManager(context).getAllPays());
this.context = context;
this.countries = countries;
}
@Override
public int getCount() {
return countries.size();
}
@Override
public Country getItem(int i) {
return countries.get(i);
}
public int getPosition(Country item) {
return countries.indexOf(item);
}
@Override
public long getItemId(int i) {
return i;
}
public int indexOf( String code) {
for (int index = 0, count = getCount(); index < count; index++)
{
if (getItem(index).getCode().equals(code)) {
return index;
}
}
return -1;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.country_list_item, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.txtViewCountryName);
//ImageView imageView = (ImageView) rowView.findViewById(R.id.imgViewFlag);
String prefix = getItem(position).getPrefix();
String code = getItem(position).getCode();
String label = getItem(position).getLabel();
textView.setText(" "+code);
String buttonID = "drawable/" + code.toLowerCase();
int resID = context.getResources().getIdentifier(buttonID, "id", context.getPackageName());
Drawable img = context.getResources().getDrawable( resID);
textView.setCompoundDrawablesWithIntrinsicBounds( img, null, null, null);
return rowView;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.country_list_item, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.txtViewCountryName);
//ImageView imageView = (ImageView) rowView.findViewById(R.id.imgViewFlag);
String prefix = getItem(position).getPrefix();
String code = getItem(position).getCode();
String label = getItem(position).getLabel();
textView.setText(" "+code);
textView.setGravity(Gravity.LEFT);
String buttonID = "drawable/" + code.toLowerCase();
int resID = context.getResources().getIdentifier(buttonID, "id", context.getPackageName());
Drawable img = context.getResources().getDrawable( resID);
textView.setCompoundDrawablesWithIntrinsicBounds( img, null, null, null);
return rowView;
}
private String GetCountryZipCode(String ssid){
Locale loc = new Locale("", ssid);
return loc.getDisplayCountry().trim();
}
}
I expect to get countries for each user from SQLite
