我robofragment不行注入意见（roboguice 2.0）

Question

我必须从我的片段roboguice膨胀的观点的问题，不知道为什么会这样..

这是我的代码

一流

public class AppController extends RoboFragmentActivity { 


@InjectView(R.id.rtlPrincipalPaginaPrincipal) RelativeLayout rtlPrincipal; 
@InjectView(R.id.rtlPrincipalMenuQr) RelativeLayout rtlMenuQr; 
@InjectView(R.id.rtlPrincipalPaginaTrasera) RelativeLayout rtlTraera; 


private FragmentManager fragment_manager; 


public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 

    objFragmenManager = AppController.this.getSupportFragmentManager(); 
     setContentView(R.layout.activitylayout); 

    objAnimationbjar = AnimationUtils.loadAnimation(this, R.anim.linear); 
    objAnimationSubir = AnimationUtils.loadAnimation(this, R.anim.linear2); 
      final SharedPreferences prefs = 
        AppController.this.getSharedPreferences("MisPreferencias",Context.MODE_PRIVATE); 



    LlenarHandler();//para podr recibir llamadas de las otras clases 
    LlenarPaginaPrincipal();// pagina principal donde mostramos las poromociones 


} 
private void LlenarPaginaPrincipal(){ 
    objNavegar = new Cnavegar(); 

    Cnavegar objNavegar= new Cnavegar(); 
    Fragment frmTopmen = new AfrmProciones(); 
    objNavegar.RemplazarFragmento(R.id.rtlPrincipalPaginaTrasera,frmTopmen, "AfrmProciones",objFragmenManager); 




} 

现在片段

public class AfrmProciones extends RoboFragment{ 


@InjectView(R.id.btnCity) Button btnBajar; 
     @InjectView(R.id.vfShow) ViewFlipper vfPromociones; 
     @InjectView(R.id.prgProgresoPomos) ProgressBar pgrProgreso; 
     @InjectView(R.id.Crono) Chronometer objCrono; 

View vPromos; 

private Handler mHandler; 
private static final int SWIPE_MIN_DISTANCE = 120; 
private static final int SWIPE_THRESHOLD_VELOCITY = 200; 
ArrayList<Cpromocion> lstPromo; 

@SuppressWarnings("deprecation") 
private final GestureDetector detector = new GestureDetector(new MyGestureDetector()); 

AccesoBd objAcceso; 
Promociones taspromociones; 
ObjectAnimator objAnimFondo; 
AlarmManager objAlarma; 
BroadcastReceiver objBroadcast; 
int itiempo; 

public AfrmProciones(Handler rHandler){ 
    mHandler = rHandler; 
} 

public AfrmProciones(){ 

} 



@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
    super.onCreateView(inflater, container, savedInstanceState); 


    RoboGuice.getInjector(getActivity()).injectMembers(this); 






RegistrarEventos(); 


LlenarPromociones(); 







    return vPromos; 
     } 






private void RegistrarEventos(){ 
    btnBajar.setOnClickListener(new OnClickListener(){ 


     public void onClick(View v) { 
      Message msg = new Message(); 
      msg.setTarget(mHandler); 
      msg.obj = "TriggerMenu"; 
      msg.sendToTarget(); 
     } 

    }); 

    vfPromociones.setOnTouchListener(new OnTouchListener() { 
     @Override 
     public boolean onTouch(final View view, final MotionEvent event) { 
      detector.onTouchEvent(event); 
      return true; 
     } 
    }); 


    objCrono.setOnChronometerTickListener(new OnChronometerTickListener() { 

     @Override 
     public void onChronometerTick(Chronometer chronometer) { 
      // TODO Auto-generated method stub 

      if (itiempo==2){ 
       vfPromociones.showNext(); 
       itiempo=0; 
      }else{ 

       itiempo+=1; 
      } 



     } 
    }); 

}

我一直在寻找云，我找不到任何与此相关的东西。 事实上，如果他们扩展它，它会正确注入robofragmentactivity，一旦发生这种情况robofragment停止为我工作。

是由于这个原因我要离开设置？

感谢

在RoboFragment，视图将在onViewCreated方法注入。

您的RegistrarEventos()方法在此之前被调用，所以当您尝试引用btnBajar视图时，您将获得NullPointerException。

注：在Java中，这是习惯使用小写首字母，以及类
