2nd spinner value depends on the first spinner selection value? — Shiladittya Chakraborty, Oct 15 '15 at 10:09
yes if value of spinner 1 changes spinner 2 should set to dafault value i.e. 0 — VaibhaV Deshmukh, Oct 15 '15 at 10:21
Check my answer and when first item select then set 2nd spinner default value using this spinnerObject.setSelection(position) // Default position may be 0. — Shiladittya Chakraborty, Oct 15 '15 at 10:24

I hope this code helps you.

ArrayAdapter<String> secondspinnerAdapter;
ArrayAdapter<String> firstspinnerAdapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_item, firstspinnervalue);

first_spinner.setAdapter(firstspinnerAdapter);      
firstspinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
firstspinner.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {                       
                        // set data in arraylist.
                      secondspinnerAdapter = new ArrayAdapter<String>( mainActivity.this,  android.R.layout.simple_spinner_item,  arraylistvalue);
                      second_spinner.setAdapter(secondspinnerAdapter);
                      second_spinner.setSelection(arg2, false);
                      secondspinnerAdapter.setDropDownViewResource
                      (android.R.layout.simple_spinner_dropdown_item);

            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {

            }
        });

You can use spinnerObject.setSelection(DEFAULT_INDEX) to set the second spinner when you want to change it back to it's default.

spinnerObject.setSelection(0);

DEFAULT_INDEX is a placeholder, you should put your default index in there. – vguzzi Oct 15 '15 at 10:15
It can be a position. Can be int number. – Shiladittya Chakraborty Oct 15 '15 at 10:15
