handler 이용해서 주기적으로 데이터 갱신

Question

public class BusDetail extends Activity{
 TextView busDetail;
 static MyItemId idList;
 ArrayList<MyItemId> items;
 ArrayList<String> stNmItem;
    ProgressDialog mProgress;
    boolean mRaw;
    TextView busName;
    ArrayAdapter<String> adapter2;
    ListView list;
    boolean keep=false;
    
 public void onCreate(Bundle savedInstanceState){
  super.onCreate(savedInstanceState);
  setContentView(R.layout.busdetail);
  
  busDetail=(TextView)findViewById(R.id.detail);
  busName = (TextView)findViewById(R.id.busName);

  items=new ArrayList<MyItemId>();
  
  items.add(idList);

코드는 위와 같은데 downthread랑 핸들러는 댓글에 남깁니다..핸들러를 10초 주기로 계속 시행되게 하고 싶은데요.. 아 지금 코드와는 별개로 만약에액티비티를 꺼도 10분 주기로 계속 핸들러를 불러내서 데이터를 갱신하려고 하면 어떻게 하면 좋을까요??ㅠㅜ
