如何自定义列表视图搜索我不将数组列表传递给自定义列表视图类

Question

编辑：这个答案不适合我，我需要根据我的情况更多的答案，谢谢

当我调用列表视图时如何使用自定义列表视图进行搜索我不传递数组。 现在我想对姓名和手机号码进行搜索，请问我该如何实现？ 姓名和手机号码有复选框，如果姓名复选框被选中然后搜索姓名如果选中手机号码复选框然后搜索手机号码

我在google上搜索过，但我不明白如何实现？

Answer 1

罗希特 - 抱歉，但乍一看，我发现了许多潜在的问题。没有时间构建和运行您的代码，我只能猜测您的具体要求。我将讨论前两个重构机会。我的直觉认为你会在这个过程中找到答案。

首先，您在 Activity 初始化之前调用了一个名为“showList()”的方法。 （在我看来，你应该稍后再调用这个方法。例如，在 onResume 中。）

然后您将创建在 onCreate 运行后将不在范围内的局部引用变量（每个实例仅发生一次）。

顺便说一句，当内联类定义（例如新的 View.OnClickListener）解析为适当的命名类和/或类的实例是成员变量时，我发现这类问题更容易解决。如果此类更改可能会导致内存管理问题，您可以在您的程序按用户预期运行后进行优化。

祝你好运！

您需要将在editext中输入的字符串传递给您的过滤器

youradapter.getFilter().filter(s);
youradapter.notifyDataSetChanged();

在你的适配器类中覆盖 getFilter() 和 performFiltering(params)

  @Override
  public Filter getFilter() {
   return new Filter() {
        @Override
       protected void publishResults(CharSequence constraint, FilterResults results)                  {
           if (results != null && results.count >= 0) {
              //set reeulst
           } else {
               // set original values
           }

           notifyDataSetInvalidated();
       }



      @Override
       protected FilterResults performFiltering(CharSequence constraint) {
           FilterResults result = new FilterResults();
           if (!TextUtils.isEmpty(constraint)) {
                  ArrayList<type> foundItems = new ArrayList<type>();
                       //do something
                       //filter resutls 
                 }

               result.count = foundItems.size();//search results found return count
               result.values = foundItems;// return values

           else
           {
               result.count=-1;// no search results found
           }
              return  result;
      }

我不知道是否有人会为你编码。但是，如果您尝试一下，您应该能够进行更改以在您的代码中实现相同的功能..
