推荐答案

我想你自己实施的过滤器。当你不能让两个过滤器，你可以在它定义了要由应用类型的​​筛选（你可以使用过滤器中的多个过滤器）。

I suppose that you implemented the filter yourself. As you cant get two filters you could have a field in the filter that defines what kind of filtering should by applied ( you could use multiple filters in your filter).

使用过滤器之前设置你的过滤器，你想要的价值的领域。

Set you field of the filter to the value you want before using the filter.

或者

使用关键字来选择过滤器适用。添加的关键字的某些字符限定了过滤器应用的开始。随着 String.beginsWith（）您可以检查哪些类型的过滤已经被应用。这必须在过滤器本身完成。在getFilter.filter（关键字）的调用方必须知道要在字符串前面加什么字。

Use the keyword to choose the filter to apply. Add on the beginning of the keyword some characters which define the filter to apply. With String.beginsWith() you can check which type of filtering has to by applied. This has to be done in the Filter itself. The caller of the getFilter.filter(keyword) has to know what characters have to by added in front of the string.
