java - How do ListActivities work with ListViews in Android? -


As a C # developer, I am trying to get acquainted with Java and more specifically the Android Framework.

I have created some very basic introduction actions, but now I am trying to get and get a list view with 'listed'. I found this sample code:

I do not think I have fully understood the concept of these ideas so far, because at the beginning I thought that the ListActivity class that I created was of some kind of user Will be made in the form - the company that I can replace my listView with just whenever I see the code, it seems as if it is trying to hook in an existing view that confuses me (How do I call this inventory activity from my current activity, and how do I use it with my list view?). 

  getListView () SetEmptyView (progressbar); Can anyone please explain what's going on? Maybe I've become too The NET pattern is centered and I do not understand the image properly. A ListActivity is an activity that assumes that you have a list with a specific ID with a list view.

Will set a layout. It will then store that scene in a variable so that getListVew () will return it. Actually, a little bit of syntactic sugar to do that you can do yourself with 3 lines of code.

Actually I do not think the value of its use can you use the listview in a regular activity, each code for ListActivity takes 1-3 lines, and if you do not have the problem You give your list name with a different ID or if you decide not to visit any list below the road

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
