StableArrayAdapter vs ArrayAdapter
android, listview
Solution
The two previous answers are absolutely right, but just to address more directly your question and in case someone else has the same doubt than you; a regular ArrayAdapter is not dangerous at all, the only "problem" is that it might not fulfill your needs, in which case you will have to create your own adapter, as the author of the tutorial did by creating what he called StableArrayAdapter in the end of the ListViewExampleActivity class.
Don't get lost by the name, which I guess comes from the fact that the overwritten method "hasStableIds" always returns true, it doesn't mean that the regular ArrayAdapter creates problems.
Problem
I am looking at this `ListView` Tutorial: ListView Tutorial and I was wondering how much better is to create my own `ArrayAdapter`, rather than just using and `ArrayAdapter`. In the Tutorial it defines a "`StableArrayAdapter`", what exactly does this means? If I use a regular `ArrayAdapter`, could it be dangerous for some reason?
