android – 如何从其他活动中调用服务中的方法

概述我有问题如何在服务中调用我的方法,我的方法是getambil_jmlgangguan(). 详细代码如下： public class GetCountDataGangguanService extends Service { public String JUMLAH_GANGGUAN =""; public static final String TAG = "MyService 我有问题如何在服务中调用我的方法,我的方法是getambil_jmlgangguan().

详细代码如下：

public class GetCountDataGangguanService extends Service {    public String JUMLAH_GANGGUAN ="";    public static final String TAG = "MyServiceTag1";    GlobalKoneksi konek_url = new GlobalKoneksi();      GetJmlGangguanFunction jmlGangguanFUnctions = new GetJmlGangguanFunction();    private static String KEY_SUCCESS = "success";    private static String KEY_JUMLAH_DATA = "jumlah";    JsONArray jml_data_Json = null;    // UserFunctions userFunctions;    UserFunctions userFunctions = new UserFunctions();    SessionManager session;    @OverrIDe    public voID onCreate() {        // Todo auto-generated method stub        mHandlers = new ArrayList<Handler>();        Toast.makeText(this,"GetCountDataGangguan.onCreate()",Toast.LENGTH_SHORT).show();        //getambil_jmlgangguan();    }    @OverrIDe    public IBinder onBind(Intent intent) {        // Todo auto-generated method stub        Toast.makeText(this,"GetCountDataGangguan.onBind()",Toast.LENGTH_SHORT)                .show();        return messenger.getBinder();    }    public class LocalBinder extends Binder {        public GetCountDataGangguanService getServerInstance() {            return GetCountDataGangguanService.this;        }    }    @OverrIDe    public voID onDestroy() {        // Todo auto-generated method stub        Log.d("GetCountDataGangguan.onDestroy()","Sudah di destroy");        Toast.makeText(this,"GetCountDataGangguan.onDestroy()",Toast.LENGTH_SHORT).show();        super.onDestroy();              }    @OverrIDe    public voID onStart(Intent intent,int startID) {        // Todo auto-generated method stub        super.onStart(intent,startID);    }    @OverrIDe    public boolean onUnbind(Intent intent) {        // Todo auto-generated method stub        Toast.makeText(this,"GetCountDataGangguan.onUnbind()",Toast.LENGTH_SHORT).show();        return super.onUnbind(intent);    }    public String getambil_jmlgangguan(){        session = new SessionManager(getApplicationContext());        session.checkLogin();        HashMap<String,String> user = session.getUserDetails();        String unit_ID = user.get(SessionManager.KEY_UNITID);        String regu_ID = user.get(SessionManager.KEY_REGUID);        JsONObject Jsondatagangguan = jmlGangguanFUnctions.getcountdata(                regu_ID,unit_ID);        try {            Log.d("JUMLAH_GANGGUAN",Jsondatagangguan.getString(KEY_JUMLAH_DATA));                JUMLAH_GANGGUAN = Jsondatagangguan.getString(KEY_JUMLAH_DATA);        } catch (JsONException e) {            e.printstacktrace();        }        return JUMLAH_GANGGUAN;    }}

如何在另一个活动中调用方法getambil_jmlgangguan(),例如MainActivity,并定期获取JUMLAH_GANGGUAN的结果.
