刷新片段在重新加載或在旋轉後

Question

我在旋轉屏幕時編寫了以下代碼片段重新生成。

片段setArguments是一個「java.lang.IllegalStateException」錯誤發生。

還有什麼更好的方法呢？

的參考：retain the fragment object while rotating

的參考：refresh fragment at reload

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    String tag = "my_fragment"; 
    FragmentManager fragmentManager = getFragmentManager(); 
    Fragment f = fragmentManager.findFragmentByTag(tag) 
    if(f == null) { //or if(null == savedInstanceState){ 
     //create Fragment 
     FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction(); 
     Fragment homeFragment = new Home(); 
     fragmentTransaction.add(R.id.mainFragement, homeFragment, tag); 
     fragmentTransaction.commit(); 
    } else { 
     //renew Fragment 
     Bundle newArgs = //want to renew Args 
     f.setArguments(newArgs); 

     ft.detach(f); 
     ft.attach(f); 
     ft.commit(); 
    } 
}

對不起。
我自己解決了，謝謝。

} else { 
    //renew Fragment 
    f.getArguments().putInt(XXXXXXX, x); 
    f.getArguments().putSerializable(XXXXXXX, X); 

    FragmentTransaction ft = fragmentManager().beginTransaction(); 
    ft.detach(f); 
    ft.attach(f); 
    ft.commit(); 
}
