Activity中启动服务(注:LocalService.class继承于Service)

方法1

//启动服务
         Intent intent=new Intent(this,LocalService.class);
         startService(intent);

方法2

LocalService localService=null;
    //用bindService方法启动服务
    private void BinderService(){
         Intent intent=new Intent(this,LocalService.class);
         bindService(intent, new ServiceConnection(){
            @Override
            public void onServiceConnected(ComponentName componentName, IBinder binder) {
                //调用bindService方法启动服务时候，如果服务需要与activity交互，
                //则通过onBind方法返回IBinder并返回当前本地服务
                localService=((LocalService.LocalBinder)binder).getService();
                //这里可以提示用户,或者调用服务的某些方法
            }
            @Override
            public void onServiceDisconnected(ComponentName componentName) {
                localService=null;
                //这里可以提示用户
            }
         }, Context.BIND_AUTO_CREATE);
    }
