I have created a spinner having categories, and now I want to add the doctor's name in the subcategories, but I am not able to do it.

What I have tried:

       String[] categories = {"All","Surgeon","Pediatrician","Cardiologist","Dermatologist"};
        ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_spinner_item,categories);
//Setting the ArrayAdapter data on the Spinner
        drspin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                String a = drspin.getSelectedItem().toString();


            public void onNothingSelected(AdapterView<?> parent) {

"add the doctor's name in the subcategories, but I am not able to do it."
Where is the name obtained from, where do you want to display it, and what do you mean by "I am not able to do it"?

Have you considered an ExpandableListView instead? It's made for such a thing.

No, I haven't tried it.
