In simple terms, you have to register for ItemSelectedListener for Spinner 1 and based on selected value, set adapter of Spinner2

Code snippet :

spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
                if(position==1)
                  adapterForSpinner2=new ArrayAdapter..... //Depends on your data
                else if(position==2)
                   adapterForSpinner2=new ArrayAdapter.....//Depends on your data

                //Setting up adapter based on selection  
                spinner2.setAdapter(adapterForSpinner2);        
            }

            @Override
            public void onNothingSelected(AdapterView<?> parentView) {
                // your code here
            }

        });
