About | ||
===== | ||
|
||
This is the **SIMPLEST** [Section Adapter][google-search] available for Android. Works with any custom adapter that you already have. No project specific dependencies. Just include the [jar][jar-download] or the sources[github-project] to your Android project. | ||
|
||
Pros | ||
---- | ||
|
||
- The simplest implementation requires just *6 lines* of code. | ||
- Zero project specific dependencies. | ||
|
||
Versions | ||
------- | ||
|
||
- Android 1.6 and up | ||
|
||
Implementation | ||
-------------- | ||
|
||
// 1. Create a Sectionizer | ||
class BookSectionizer implements Sectionizer<Book> { | ||
|
||
@Override | ||
public String getSectionTitleForItem(Book book) { | ||
return book.getGenre(); | ||
} | ||
} | ||
|
||
// 2. Wrap your existing adapter with the SimpleSectionAdapter | ||
.... | ||
sectionAdapter = new SimpleSectionAdapter<Book>(this, | ||
yourBookAdapter, R.layout.section_header, R.id.title, | ||
new BookSectionizer()); | ||
... | ||
|
||
OnItemClickListener | ||
------------------- | ||
While using an [OnItemClickListener][item-click-listener] instead of using the list item's position directly, use is as shown below. | ||
|
||
@Override | ||
public void onItemClick(AdapterView<?> parentView, View view, int position, long id) { | ||
int actualPosition = sectionAdapter.getUndecoratedItemPosition(position); | ||
|
||
// More code... | ||
} | ||
|
||
|
||
FAQs | ||
---- | ||
- **Can I use SimpleSectionAdapter with ArrayAdapter or CursorAdapter?** | ||
<br />Yes, you can use [SimpleSectionAdapter][simple-section-adpater] with any adapter that extends [BaseAdapter][base-adapter]. | ||
|
||
- **Are there any resource files that has to be included with my project?** | ||
<br />No, you don't have to include anything beyond the SimpleSectionAdapter and the Sectionizer. | ||
