android - Does cursor adapter query db multiple times or does it cache the full result? -

I'm new to Android and trying to execute the basics. So as you scroll through a list, does it hit DB like you, or it raises the rows from the cache?

- If it kills DB, then why do most docs say that it is better than the supply of a base adapter with an overlink. At least in this way I only hit DB once.

- If it is not in the cache and puts everything, then it provides with a full list like using a full adapter. > Why am I still confused as most people say the cursor adapter is more efficient?

Thanks, Mick

If any cursor wants to know more about the adapter So he can see here:
