        mTvBookmarkCount.setText(BookmarkCount);
        List mBibleBookLights = DBManager_Light.getInstance(getActivity()).queryBibleBookLight();
        String HightlightCount=mBibleBookLights.size()+"";
        mTvHightlightCount.setText(HightlightCount);
        List mBibleBookNote = DBManager_Note.getInstance(getActivity()).queryBibleBookNote();

@Override
public void setUserVisibleHint(boolean isVisibleToUser) {
    super.setUserVisibleHint(isVisibleToUser);
    if (isVisibleToUser){
        List mBibleBookmarks = DBManager.getInstance(getActivity()).queryBibleBookmarks();
        String BookmarkCount=mBibleBookmarks.size()+"";
        mTvBookmarkCount.setText(BookmarkCount);
        List mBibleBookLights = DBManager_Light.getInstance(getActivity()).queryBibleBookLight();
        String HightlightCount=mBibleBookLights.size()+"";
        mTvHightlightCount.setText(HightlightCount);
        List mBibleBookNote = DBManager_Note.getInstance(getActivity()).queryBibleBookNote();
        String NoteCount=mBibleBookNote.size()+"";
        mTvNoteCount.setText(NoteCount);
    }
}

这两个总会有一个惯用的，你自己试试。原理是显示即刷新。
