How to do 2nd Spinner get selected , based on my 1st Spinner selection?

Question

I am using Two Spinner in my App . 1st Spinner is array of STATE, 2nd Spinner is array of COUNTRY. Also i am using Spinner with key-value in easy way, ie :

A - Spinner State:

i take an Array of states using as [KEY],

 []state = {"UP","MP",... ,"OUT SIDE INDIA"};

Also i take an another Array of states using as [value]

[]state_id = {"111","222",......"999"};

Both the above Array are identical in size.

B - Spinner Country:

i take an Array of country using as [KEY],

 []country = {"USA","UN",... ,"INDIA"};

Also i take an another Array of country using as [value]

[]country_id = {"01","01",......"200"};

Both the above Array are identical in size.

AND i am getting data [VALUE] of selected item of Spinner , like

    @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            String value = state_id[arg2];
        }  

My Question is , How do i control 2nd Spinner [country] , if i select in 1st Spinner [state] ?

for example , i want to select UP , than 2nd Spinner should be auto select on INDIA as disabled.

Answer 1

make a checque on item selected in first spinner and then according to item selected in 1st spinner set value in second spinner...
eg.spinner.setselection(2);

check will be like

if(spinner1.getselecteditem==1)
     {


          spineer2.setselection(2);

       }
