Spinner Spinner = (Spinner) findViewById(R.id.spinner);

    public void onClick(View v) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onItemSelected(AdapterView<?> arg0, View view,
            int position, long row_id) {
        final Intent intent;
        switch(position){
            case 1:
                intent = new Intent(CurrentActivity.this, TargetActivity1.class);
                break;
            case 2:
                intent = new Intent(CurrentActivity.this, TargetActivity2.class);
                break;
// and so on

        }
        startActivity(intent);

    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub
