Android : How to call activity inside running activity?

Question

I am thinking to split the activity into two parts :

1. List view : show the files.

2. Second part will an activity contain the selected file.

its possible to do that, like frames in HTML ?

Answer 1

I think what you want to be doing is using activity fragments. The guide topic Fragments describes how to do pretty much exactly what you're talking about. To support pre-3.0 Android systems, you'll need to use the compatibility package.
