最好的解决方案：

  mListView.setOnScrollListener(new OnScrollListener() {

                    

                    @Override

                    public void onScrollStateChanged(AbsListView view, int scrollState) {

                        if(scrollState == SCROLL_STATE_TOUCH_SCROLL){

                            View currentView = getActivity().getCurrentFocus();

                            if(currentView != null){

                                currentView.clearFocus();

                            }

                        }

                    }

                    

                    @Override

                    public void onScroll(AbsListView view, int firstVisibleItem,

                            int visibleItemCount, int totalItemCount) {

                        // TODO Auto-generated method stub

                        

                    }

                });
