AndroidAnnotations에서 런타임 오류가 발생했습니다.

Question

내 앱에서 AndroidAnnotations를 사용하고 있으며, 의도에 추가하고 AndroidAnnotations를 사용하는 활동을 시작하려고 할 때 항상 런타임 오류가 발생합니다. AndroidAnnotations 사용을 중지하면 모든 것이 정상적으로 작동합니다. 여기

public class TimeAndDateShower extends Activity { 
//some code 

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.time_and_date_shower); 
     //some code 
     setButtonListener(); 

    } 
public void setButtonListener() 
    { 
     Button button = (Button) findViewById(R.id.button1); 
     button.setOnClickListener(new OnClickListener() 
     { 
      public void onClick(View v) 
      { 
       Intent intent = new Intent(TimeAndDateShower.this, DateChooser_.class); 
       intent.putExtra("SSID", network); 
       startActivity(intent); 
       TimeAndDateShower.this.finish(); 
      } 
     }); 
    } 
} 

처럼 DateChooser.java 보이는 방법은 다음과 같습니다 :이 같은 DateChooser 구성 활동을 선언의 AndroidManifest.xml에서

@EActivity(R.layout.date_chooser) 
public class DateChooser extends Activity { 

    public String network; 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //setContentView(R.layout.date_chooser); 

     setNetworkName(); 
     //some code 
    } 

    public void setNetworkName() 
    { 
     TextView textView = (TextView)findViewById(R.id.textView4); 
     network = this.getIntent().getStringExtra("SSID");//using an extra 
     textView.setText(network); 
    } 

}

내 활동을 시작하는 코드입니다

name="com.componentix.imwizard.DateChooser_" android:screenOrientation="landscape"> </activity> 

그리고 여기 내 런타임 오류의 로그입니다 :

NPE가 textView에있는 것 같습니다. 원래의 oncreate() 메소드 다음에 생성 된 클래스에서 레이아웃 주입이 수행됩니다. 또한, 금주 모임에 여분의 자료와 견해를 주입시켜야합니다. 다만이 같은 클래스를 업데이트

@EActivity(R.layout.date_chooser) 
public class DateChooser extends Activity { 

    @Extra("SSID") 
    String network; 

    @ViewById(R.id.textView4) 
    TextView textView; 

    @AfterViews 
    void init() { 
     textView.setText(network); 
     //some code 
    } 

}
