How could we pass a different value on an Item select from android spinner than the text which we select in spinner? [closed]

Answer 1

Create your Object pojo like

class Country{
 String name;
String  code;

//getter and setters
    }

and set list of Country List<Country> list; to adapter

Show country name and access country code

spinner.getSelectedItem().getCode();

Answer 2

Instead of passing the full country name, you can get the selected country and call on str.substring(0, 3).toUpperCase()

Answer 3

This can do for two things, one if you want to use in code but not want to see in selection other name, and second one is if you want to display name in spinner and also use in code check below solution.

Create one common class to store country names and country codes like below

CommonClass.java

  //I am taking it as CommonClass you can change it.

  public static final String[] strCountryNames = {"India","Italy","Afghanistan","United States of America"};

  public static final String[] strCountryCodes = {"IND","ITA","AFG","USA"};

Now, For spinner setAdapter use CommonClass.strCountryNames,

And where you want to use code there use CommonClass.strCountryCode,

Suppose you want to get code for India, then you can check it as

 CommonClass.strCountryCode[spinner.selectyedPosition];

Answer 4

if you want first three latter of name

String countryName = "China"
String shortName = countryName.substring(3).toUpperCase();

Answer 5

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
       public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
         int pos = spinner.getSelectedItemPosition();
String mysourcestring= yourarraylistname[+pos];
String substr=mysourcestring.substring(0,3).toUpperCase();
}
 @Override
       public void onNothingSelected(AdapterView<?> parent) {

      }
});

now the value you want to pass will be in substr. sorry if any errors, hope this helps
