活動已被破壞在fragmenttransaction.commit

我的項目結構如下：我有一個活動調用一個片段。我的目標是能夠簡單地將片段從1切換到另一個片段。我創建了一個新的類來處理下面顯示的點擊。我成功地輸入我的1的情況下，因爲它出現在我的logcat。我的問題出現之後由於某種原因，我無法切換碎片。我試圖切換到的片段是聊天室。活動已被破壞在fragmenttransaction.commit

我現在試圖得到碎片的懸掛，所以任何幫助將做。如有必要，我也可以發佈我的Activity類。謝謝。

下面是我的onClickListener類：

/** 
* Created by Programmer 552 on 10/7/2014. 
*/ 
public class ClickityClickClick implements View.OnClickListener { 

    public static String DEBUG = "Debug"; 
    private LetsPutInAChatBox activity = new LetsPutInAChatBox(); 
    private ChatFragment chatty = new ChatFragment(); 

    private int test; 


    public ClickityClickClick(int test) { 
     this.test = test; 
    } 

    @Override 
    public void onClick(View v) { 
     switch (test) { 
      case 1: 
       Log.d(DEBUG, "IN THE METHOD"); 
       addFragments(chatty); 

     } 
    } 

    public void addFragments(Fragment fragment) { 
     FragmentManager manager = activity.getFragmentManager(); 
     FragmentTransaction ft = manager.beginTransaction(); 
     ft.replace(R.id.container, fragment); 
     ft.commit(); 
    } 
}

這裏是我的片段，我想用我的addFragments方法來調用：

public class ChatFragment extends Fragment { 
    LetsPutInAChatBox activity; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     activity = new LetsPutInAChatBox(); 
     View rootView = inflater.inflate(R.layout.chat_box, container, false); 

     return rootView; 
    } 

    @Override 
    public void onAttach(Activity activity) { 
     this.activity = (LetsPutInAChatBox) activity; 
     super.onAttach(activity); 
    } 

}

刪除此行activity = new LetsPutInAChatBox（）;從onCreateView？ – 2014-10-08 05:07:51

我剛試了一下，崩潰了。同樣的錯誤。 – Programmer552 2014-10-08 05:10:26

您的活動類是ClickityClickClick，但您的類型轉換爲LetsPutInAChatBox。刪除類型轉換並運行 – 2014-10-08 05:17:47

當你提交代碼，請確保您的活動沒有完成。 so like like this：

if (!isFinishing()) { 
      fragmentTransaction.commit(); 
     }
