Extending fragments using a list

Question

I work with fragments in android, extend android.app.ListFragment to display a listview, but it only takes up one element in the list view. I want to display 2 elements as a list, this is possible with the extension of the ListActivity class, but I want to expand both the fragment and listactivty.

Answer 1

Nothing prevents you from showing everything you want in a ListView element. Please read the ListFragment API ListFragment .

You can create a ListAdapter that returns a View the type you want to use in the getView method. In this regard, there is hardly any difference between ListActivity and ListFragment .

Answer 2

It is impossible to expand both a fragment and activity classes to one class. Thus, extends Activity to the main class and creates an inner class and extends the Fragment class.
