Multi-column listviews

Question

Is it possible to define a different multi-column approach for a list view in portrait and landscape? For example on the Android market you have two columns when scrolling through apps in portrait mode but 3 columns in landscape.

I couldn't see a way of defining two "positions" within one layout row in the custom adapters and no way of specifying that the ListView has two different list items within one row. Should I be using a different sort of layout?

Answer 1

If you add the two folders :

layout-land
layout-port

In each of these folders there is the same file, say myRowLayout.xml

When your device is in landscape mode, myRowLayout.xml that is in the folder layout-land will be used, while that in layout-port will be used when in portrait mode.

Answer 2

The Market App is not using a ListView it is using a GridView see the Hello GridViewTutorial for more info.

A GridView can use the same Adapter as a listview but it will position items in a grid with multiple columns. You could either specify the number of columns in a ressource file and then distinguish with values-port values-xhdpi etc. or you can make the GridView to choose for itself how many columns should be shown.
