有时搜索视图在listview中无法正常工作

Question

我在listview中有酒店菜单项。在dat listview中我有带搜索功能的edittext。我必须按项目名称和区域搜索酒店项目。工作正常。但有时在搜索时按区域显示它没有显示任何内容。如果我重新打开该应用程序并且搜索意味着它正常工作。我不知道错误发生在哪里。请帮助我....

        String text = mSearch.getText().toString().toLowerCase();

         arrayTemplist= new ArrayList<HotelItem>();


            for (int i = 0; i < searchItems.size(); i++)
