As a beginner, It is difficult to bind the data to Spinner (Drop down). If we consider HTML, it is easy to add option values to the drop down. But In Android, we have to use Adapters to bind the data. So here I am targeting my approaches to bind to the Spinner.
Binding static Array to the spinner
Binding resource Array to the Spinner
Binding resource Array to the Spinner Using ArrayAdapter.createFromResource

Binding static Array to the spinner
static final String[] COUNTRIES = new String[] { "India", "US", "UK", "Sri Lanka", "Austraila", "Denmark", "Saudi" }; Spinner spCountry = (Spinner) findViewById(R.id.spCounty); ArrayAdapter<CharSequence> adCountry = new ArrayAdapter<CharSequence>( this, android.R.layout.simple_spinner_dropdown_item, COUNTRIES); adCountry.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spCountry.setAdapter(adCountry);
Binding resource Array to the Spinner
Spinner spCities = (Spinner) findViewById(R.id.spCities); String[] cities = getResources().getStringArray(R.array.arr_cities); ArrayAdapter<CharSequence> adCities = new ArrayAdapter<CharSequence>( this, android.R.layout.simple_spinner_item, cities); adCities.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spCities.setAdapter(adCities);
Binding resource Array to the Spinner Using ArrayAdapter.createFromResource
Spinner spLocalities = (Spinner) findViewById(R.id.spLocality); ArrayAdapter<CharSequence> adLocalities = ArrayAdapter .createFromResource(this, R.array.arr_localities,android.R.layout.simple_spinner_item); adLocalities.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spLocalities.setAdapter(adLocalities);
