团队冲刺09

昨天fragment的显示以及刷新的问题。
今天对删除全部信息设置确认密码的功能。

//刷新listview
    public void refreshListView() {
        Log.d(TAG, "refreshListView: ");
        SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this.getActivity());

        dao op = new dao(this.getActivity());
        op.open();

        // set adapter
        if (noteList.size() > 0) noteList.clear();
        noteList.addAll(op.getAllNotes());
        /*if (sharedPreferences.getBoolean("reverseSort", false)) sortNotes(noteList, 2);
        else sortNotes(noteList, 1);*/
        op.close();
        adapter.notifyDataSetChanged();
    }
