xml에서 item을 선택하고난후 java에서 if문써서 item값하고 qq 값하고 참거짓을

작성하고싶은데요     aaa.getSelectedItem().toString() <--- 하면 item string값 가져오는게 아닌가여?

안되네요;;; 선택된 item값 가지고 올려면 어떻게 해야되나요?

xml 부분

<string-array name ="interest_array">
         <item>IT</item>
         <item>결제</item>
     </string-array>

java부분

         aaa =(Spinner) findViewById(R.id.spinner_interest);

        ArrayAdapter<CharSequence> adapter =
        ArrayAdapter.createFromResource(this, R.array.interest_array, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner.setAdapter(adapter);
         findViewById(R.id.button1).setOnClickListener(new Button.OnClickListener(){
    public void onClick(View arg0) {
   // TODO Auto-generated method stub
  

String qq = "IT";

if(aaa.getSelectedItem().toString() != qq)

  {
   AlertDialog.Builder aa = new AlertDialog.Builder(Project13Activity.this);
   aa.setMessage( "관심분야 : " + aaa.getSelectedItem().toString());
   aa.setPositiveButton("확인", new OnClickListener() {
      
   
    public void onClick(DialogInterface dialog, int which) {
        // TODO Auto-generated method stub
       
       }

   
      });

   aa.show();
