Question

我在MainActivity中使用三個片段。

它來自fata例外：main。說， 的RequestFragment.class線54是例外的原因：

adapter = new RequestAdapter(getListView().getContext(), mRequests); 

的RequestAdapter是separatedly implementated類。

謝謝！ 代碼：

@Override 

public void onResume() { 

     super.onResume(); 

     getActivity().setProgressBarIndeterminateVisibility(true); 
     currentUserName = ParseUser.getCurrentUser().getUsername(); 
     getActivity().setProgressBarIndeterminate(true); 
     ParseQuery<ParseObject> query = new ParseQuery<ParseObject>(ParseConstants.CLASS_ACTIVITYREQUEST); 
     query.whereEqualTo(ParseConstants.KEY_RECIPIENTNAME, currentUserName); 
     //Reorder the result according to the time users shake the phone 
     query.addDescendingOrder(ParseConstants.KEY_CREATEDAT); 
     query.findInBackground(new FindCallback<ParseObject>() { 

      @Override 
      public void done(List<ParseObject> requests, ParseException e) { 
       getActivity().setProgressBarIndeterminateVisibility(false); 
       if(e == null){ 
        mRequests = requests; 
        adapter = new RequestAdapter(getListView().getContext(), mRequests); 
        setListAdapter(adapter); 
       } 
       else{ 
        Log.d(TAG, "no request"); 
       } 
      } 
     }); 
    }

你必須在這裏

adapter = new RequestAdapter(getListView().getContext(), mRequests); 

改變

adapter = new RequestAdapter(getActivity(), mRequests);
