I've a two column layout and want it working like the "Settings" on a android 4 on a tablet.
On the left a menu (it's a ListView) and depending on the action on the list view I want to load an activity on the right column.
How can I achieve this? I'm unsure of what keywords to use to search for a solution.
Sounds like you want fragments. What you would do is create an activity that allows for two fragments which you can customize how you want.
