활동 사이를 전환 할 때 크로노 미터를 실행하는 방법

Question

저는 크로노 미터가 있습니다. 특정 활동에 현재있는 경우에만 작동합니다. 다른 활동으로 계속 전환하려면 크로노 미터를 계속 작동 시키십시오. 지금까지해야 할 일이 지금까지 제 코드입니다. 내가 구현 한 것. 미리 감사드립니다 !!!

솔루션

private View rootView;// Cache view 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) 
    { 
     Log.i(TAG, "onCreateView"); 

     if (rootView == null) 
     { 
      rootView = inflater.inflate(R.layout.fragment_1, null); 
     } 
     // Cached rootView need to determine whether the parent has been added, if there is parent needs to be deleted from parent, or else will happen this rootview has a parent error. 
     ViewGroup parent = (ViewGroup) rootView.getParent(); 
     if (parent != null) 
     { 
      parent.removeView(rootView); 
     } 
     return rootView; 
    }
