How to populate listview in android studio from SQLite Database?

I need to create a listview in android studio and populate it with data from my database that I've created in SQLite Studio. So I need to display three things in my listview and these three things are in my database: an image, a description, and basically some text. I've been watching some videos and understand that you need to create a database handler class, but this doesn't connect directly to your database in SQLite and also if you do this, then you need to create the table, but my table has already been created and has data in it. I just need to connect to that database, query it, and populate the listview from that, so does anyone know how I can accomplish that?
