無法從我的自定義佈局類中調用方法

我有一個奇怪的問題，應該很簡單。我創建了自定義操作欄類，並將其放入了一些活動中。我懷疑我的自定義操作欄有方法「設置文本」和「setBackButtonVisible」。這些方法應該從我的操作欄所在的活動類中調用。重點是從我的活動類主體調用這些方法會導致錯誤。現在我被迫從我的操作欄注入按鈕/文本視圖到活動，所以我可以操縱它們。（請注意，我正在使用RoboGuice 2.0）類，正如您在錯誤日誌中看到的那樣。無法從我的自定義佈局類中調用方法

編輯：我忘了提，我MainMenuActivity躺在的TabBar

動作條類：

public class CustomActionBar extends RelativeLayout{ 

    //View v; 

    @InjectView(R.id.action_back_button) 
    Button backButton; 

    @InjectView(R.id.action_bar_text) 
    TextView tv; 


    public CustomActionBar(Context context, AttributeSet attrs){ 
     super(context, attrs); 

     LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     /*v = */layoutInflater.inflate(R.layout.action_bar, this); 

    } 

    public CustomActionBar(Context context) { 
     super(context); 

     LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     /*v = */layoutInflater.inflate(R.layout.action_bar, this); 

    } 

    // Cannot invoke those methods from MainMenuActivity 
    public void setText(String text){ 
     tv.setText(text); 
    } 

    public void setBackButtonVisible(boolean set){ 
     // invoking this method in MainMenuActivity constructor will produce funny error 
     if(!set){ 
      backButton.setVisibility(View.GONE); 
     }else{ 
      backButton.setVisibility(View.VISIBLE); 
     } 
    } 
}

活動類

@ContentView(R.layout.activity_main_menu) 
    public class MainMenuActivity extends RoboActivity { 

    @InjectView(R.id.action_back_button) 
    Button actionBackButton; 

    @InjectView(R.id.action_bar_text) 
    TextView actionBarText; 

    @InjectView(R.id.action_bar) 
    CustomActionBar actionBar; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     actionBackButton.setVisibility(View.GONE); 
     // Hardcoded title for actionbar 

     // This one works: actionBarText.setText("TEST"); 
     actionBar.setText("Main Menu"); 
    } 


    public void onBackButtonClick(View v){ 
     this.finish(); 
    } 

    }

確定。。我知道了。

這是我的糟糕的錯誤。

什麼是錯的？我調用我的自定義動作條由

@InjectView(R.id.action_bar) 
CustomActionBar actionBar;

的一點是，R.id.action_bar不動作欄ID ......這是我的主其他動作佈局ID ...
