How to set items from custom ArrayList

[bviral]

Hello Sir,

I am getting data directly from db so I am having that data in custom ArrayList not in string type ArrayList. I don't want to convert it in single column List so please tell me how to set items by specifying custom type arraylist column.

You need to create an Adapter of MaterialSpinnerAdapter Example you have:

 ArrayList<Country> countryArrayList = new ArrayList<>();
        Country country = new Country("Kenya",254);
        countryArrayList.add(country);
        Country country1 = new Country("Nigeria",244);
        countryArrayList.add(country1);
       MaterialSpinnerAdapter<County> countyMaterialSpinnerAdapter;
        countyMaterialSpinnerAdapter = new MaterialSpinnerAdapter<County> 
       (getContext(),countyArrayList);
        MaterialSpinner countrySpinner = view.findViewById(R.id.countrySpinner);
        countrySpinner.setAdapter(countryMaterialSpinnerAdapter);

        countrySpinner.setOnItemSelectedListener(new MaterialSpinner.OnItemSelectedListener<Country>() {

            @Override public void onItemSelected(MaterialSpinner view, int position, long id, Country country) {
                Snackbar.make(view, "Clicked " + country.getName() + " code = "+country.getCode(), Snackbar.LENGTH_LONG).show();
            }
        });

Remember the Country model class has this method

//to display object as a string in spinner
    @Override
    public String toString() {
        return name;
    }
