片段沒有發現的ID在android中的視圖ID更改時，它顯示兩個屏幕上覆蓋？

Question

this is the screenshot of overwritten screen of both fragments我已經搜查的網站上，但我無法找到解決辦法，這裏是我的代碼：

public class MyLawyerFragment extends Fragment { 
ImageButton im1; 
@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

    View v1 = inflater.inflate(R.layout.activity_mylawyer, 
      container, false); 
    im1 = (ImageButton) v1.findViewById(R.id.imageButton); 
    im1.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      Fragment fragment = new tasks(); 
      FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); 
      FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); 
      fragmentTransaction.replace(R.id.drawer_layout, fragment); 
      fragmentTransaction.addToBackStack(null); 
      fragmentTransaction.commit(); 

     } 
    }); 
    return v1; 
} 

}

這裏是我的下一個片段的代碼，而我想去從最後一個：

public class tasks extends Fragment { 
@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    { 

     super.onCreateView(inflater, container, savedInstanceState); 
     final View rootview = inflater.inflate(R.layout.activity_addlawyer, container, false); 



    return rootview; 
}}} 

這裏是任務片段的XML：

現在我有這個錯誤的logcat：

java.lang.IllegalArgumentException: No view found for id 0x7f0d006c (com.orion.android.mylawyerdiary:id/rel3) for fragment tasks{22ba0560 #1 id=0x7f0d006c} 

而且我無法解決它...請人幫助我。

這是所有片段連接我的導航抽屜活動的xml：

Answer 1

我改變了線按編輯，並通過添加此

if (container != null) { 
     container.removeAllViews(); 
    } 

修改addlawyer片段的onCreate方法並且它除去所有其他視圖，以便僅示出了其片段，其我選擇。

Answer 2

你的任務類中刪除此行super.onCreateView(inflater, container, savedInstanceState);

因爲如果你調用super.onCreateView方法，將爲你的片段視圖返回null。那條線以下的那條線不會被調用。

編輯： 好吧，我想你有contain_main.xml文件 更新此行fragmentTransaction.replace(R.id.rel3, fragment); 到fragmentTransaction.replace(R.id.content_container, fragment)

Answer 3

當更換片段如下代碼調用：

fragmentTransaction.replace(R.id.rel3, fragment); 

這意味着的是， Activity的視圖由ID rel3標識，應替換爲fragment。

裏面.xml視圖的Acitivty（傳遞給setContentView方法）應該有與ID rel3將由fragment被替換的視圖。
