如何在多个参数上使用SearchView过滤RecyclerView [英] How to filter Recyclerview with SearchView on multiple parameters

问题描述

我已经实现了这里给出的SearchView示例。

....以过滤并列出公司名称参数产品名称。

在我的项目中，我想扩展这个以进一步过滤城市名称参数

以下是在参数productname上过滤的onQueryTextSubmit的代码。

@覆盖
public boolean onQueryTextSubmit（String query）{
return false;
}

  private List< ExampleModel> （List< ExampleModel> models，String query）{
 query = query.toLowerCase（）; 
 
 final List< ExampleModel> filteredModelList = new ArrayList<>（）; 
 for（ExampleModel model：models）{
 final String text = model.getText（）。toLowerCase（）; 
 final String city = model.getCity（）。toLowerCase（）; 
 final String product = model.getProduct（）。toLowerCase（）; 
 final String services = model.getServices（）。toLowerCase（）; 
 final String state = model.getState（）。toLowerCase（）; 
 final String zone = model.getZone（）。toLowerCase（）; 
 if（product.contains（query））{
 filteredModelList.add（model）; 
} 
 
} 
 return filteredModelList; 
 
  

我应该如何从这里前进？

解决方案

只需在这里添加城市名称验证即可：

  if（product.contains（query）|| city.contains（query））{
 filteredModelList.add（model）; 
} 
  

I have implemented the SearchView example given here.

How to filter a RecyclerView with a SearchView

....to filter and list company names based on the parameter "Product name".

In my project, I want to extend this to further filter on the parameter on "city name"

The below is the code for the onQueryTextSubmit which filters on the parameter "productname".

@Override public boolean onQueryTextSubmit(String query) { return false; }

private List<ExampleModel> filter(List<ExampleModel> models, String query) {
    query = query.toLowerCase();

    final List<ExampleModel> filteredModelList = new ArrayList<>();
    for (ExampleModel model : models) {
        final String text = model.getText().toLowerCase();
        final String city = model.getCity().toLowerCase();
        final String product = model.getProduct().toLowerCase();
        final String services = model.getServices().toLowerCase();
        final String state = model.getState().toLowerCase();
        final String zone = model.getZone().toLowerCase();
        if (product.contains(query)) {
            filteredModelList.add(model);
        }

    }
    return filteredModelList;
}

How should I go forward from here?

解决方案

Just add the city name verification here:

    if (product.contains(query) || city.contains(query)) {
        filteredModelList.add(model);
    }
