SectionAdapter

Here's what you get with Section adapter:

• Pinned headers
• An easy method of putting your data into sectioned data without the hassle of writing routines to find the position in section, etc.
• Easily swap out assets depending on whether you're in first of section, end of section, etc. (note the rounded corner backgrounds for the listview items)
• ListView searching (optional)
• Support for "fastscroll" if specified in listview
• The model that you are populating the listview with must implement Sectionable.java

  public class Person implements Sectionable {
  
      private String name;
  
      private String city;
  
      public Person(String name, String city) {
          this.name = name;
          this.city = city;
      }
  
      public String getName() {
          return name;
      }
  
      public String getCity() {
          return city;
      }
  
      //
      @Override
      public String getSection() {
          return city;
      }
  
      /*
       * when filtering occurs, it is doing a case-insensitive search on toString()
       * for more complex matching, implement Queryable on your model
       *
       */
      @Override
      public String toString() {
          return name + " " + city;
      }
  
  
  }
  

• Simply pass a List of your Sectionable object model to the adapter..
