        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        selection = (TextView) findViewById(R.id.selection);
        Spinner spin = (Spinner) findViewById(R.id.spinner);
        ArrayAdapter<String> aa = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, countries);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spin.setAdapter(aa);
        spin.setOnItemSelectedListener(this);

        selection2 = (TextView) findViewById(R.id.selection2);
        Spinner spin2 = (Spinner) findViewById(R.id.spinner2);
        ArrayAdapter<String> bb = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, city);

        spin2.setOnItemSelectedListener(this);
    }

    public void onItemSelected(AdapterView<?> parent, View v, int position, long id ){
        Spinner spin = (Spinner)parent;
        Spinner spin2 = (Spinner)parent;
        if(spin.getId() == R.id.spinner)
        {
            Toast.makeText(this, "Your choose :" + countries[position],Toast.LENGTH_SHORT).show();                 
        }
        if(spin2.getId() == R.id.spinner2)
        {
            Toast.makeText(this, "Your choose :" + city[position],Toast.LENGTH_SHORT).show();       
        }

    }

    public void onNothingSelected(AdapterView<?> parent){
        Toast.makeText(this, "Choose Countries :", Toast.LENGTH_SHORT).show();
    }
}

when i run this activity, the first spinner value is city and the second spinner value is empty.

How do I run 2 spinner in the same activity? First spinner value is countries and second spinner value is city.

Answer 1

use

spin2.setAdapter(bb);

instead of

spin.setAdapter(bb);

currently you are setting Adapter for second spinner

Answer 2

Don't add the implementation to your Activity class

Create two inner classes that each handle one of the spinners

public class CreateComboBox extends Activity implements AdapterView.OnItemSelectedListener
{
    TextView selection;
    TextView selection2;
    String[] countries = {"Amerika","Argentina","Brazil"};

    String[] city = {"London","Paris","Buenos Aires"};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        selection = (TextView) findViewById(R.id.selection);
        Spinner spin = (Spinner) findViewById(R.id.spinner);
        ArrayAdapter<String> aa = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, countries);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spin.setAdapter(aa);
        spin.setOnItemSelectedListener(new CountriesSpinnerClass());

        selection2 = (TextView) findViewById(R.id.selection2);
        Spinner spin2 = (Spinner) findViewById(R.id.spinner2);
        ArrayAdapter<String> bb = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, city);
        bb.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spin.setAdapter(bb);
        spin2.setOnItemSelectedListener(new CitiesSpinnerClass());
    }

    class CountriesSpinnerClass implements AdapterView.OnItemSelectedListener
    {
        void onItemSelected(AdapterView<?> parent, View v, int position, long id)
        {
            Toast.makeText(v.getContext(), "Your choose :" + countries[position],Toast.LENGTH_SHORT).show();      
        }
    }

    class CitiesSpinnerClass implements AdapterView.OnItemSelectedListener
    {
        void onItemSelected(AdapterView<?> parent, View v, int position, long id)
        {
            Toast.makeText(v.getContext(), "Your choose :" + city[position],Toast.LENGTH_SHORT).show();        
        }
    }
}

Answer 3

bb.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin2.setAdapter(bb); (should be second spinner..)
^^^^^
spin2.setOnItemSelectedListener(this);

Answer 4

You should use make spin.setAdapter(bb); to spin2.setAdapter(bb);

Answer 5

I was facing many problems with spinner and finally found this solution

This library (SmartMaterialSpinner) saves you a lot of time as it provides an easy way to add as many spinner as you want, in addition to easy ways to add items to your spinners with stand alone listener

Here is how I used it in my project :

 String[] Durationarray = {"1 Month ", "2 Month ", "3 Month ", "4 Month ", "5 Month", 
         "6 Month ", "7 Month ", "8 Month ", "9 Month ", "10 Month ", "11 Month ",
            "1 Year", "2 Year", "3 Year", "4 Year", "5 Year", "6 Year", "7 Year", "8 Year", "9 Year", "10 Year"};

    spinner1 = (SmartMaterialSpinner) findViewById(R.id.spinner1_id);
    List<String> DurationList = new ArrayList();
    new WorkAround().convertStringArrToListArr(gam3iaDurationarray, DurationList);
    spinner1.setItem(DurationList);
    spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

    String[] egyptGovernemt = {"New Valley", "Matruh", "Red Sea", "Giza", "South Sinai", "North Sinai", "Suez", "Beheira", "Helwan", "Sharqia", "Dakahlia",
            "Kafr el-Sheikh" , "Alexandria", "Monufia", "Minya", "Gharbia", "Faiyum", "Qena", "Asyut", "Sohag", "Ismailia", "Beni Suef", "Qalyubia", "Aswan", "Damietta", "Cairo",
            "Port Said", "Luxor", "6th of October"};

    spinner2= (SmartMaterialSpinner) findViewById(R.id.spinner2);
    List<String>  cityList = new ArrayList<String>();
    new WorkAround().convertStringArrToListArr(egyptGovernemt, cityList);

    spinner2.setItem(cityList);
    spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {


        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

The WorkAround class to convert the string array to string arraylist

public class WorkAround {


    public void convertStringArrToListArr(String [] myStringArray, List<String> myStringList){
        for (String s:myStringArray) {
            myStringList.add( s );
        }
    }

    // Number Checker Method
    public  boolean isNumeric(String str) {
        try {
            Double.parseDouble(str);
            return true;
        } catch (NumberFormatException e) {
            return false;
        }
    }
}

Note that you don't need to implements

implements AdapterView.OnItemSelectedListener
