How to get multiple spinner in android where value of one spinner depends on value of other spinner?

I want to have dynamic spinner in android e.g o开发者_Python百科ne spinner for country and depending upon the value selected in Country, i want to get another spinner for states.

I believe you can solve this with the OnItemSelectedListener.

public void onCreate() {
     ....
    Country[] mCountries = ... ;
    final Spinner spinner1 = ...;
    final Spinner spinner2 = ...;

    spinner1.setAdapter(new ArrayAdapter(mCountries);
    spinner1.setOnItemSelectedListener( new OnItemSelectedListener() {

    void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        Country country = (Country) parent.getAdapter().getItem(position);
        spinner2.setAdapter(new ArrayAdapter(country.getStates());
     }
     void onNothingSelected(AdapterView<?> parent) {
        spinner2.setAdapter(null);
     }
    });
 ....
}
