    copied!<p>I was wondering : I'm trying to make an app that as a Listview, displaying data from a database.</p> <p>Here is the specific thing : I want that on a event that modified the database, the listview is automatically updated, as if there was a "listenner" on the database that ... well automatically upload the listview.</p> <p>From what I read, I should use a loadManager, a cursor, fragment (to allows me to use loadManager for anterior versions of 3.0) ... but as I'm a beginner, it's kind of hard to me to understand.</p> <p>I was wondering if someone could just try to explain me deeply how to use those tools together (I'm not asking for code, just explanation :) )</p> <p>Thanks !</p> <p>EDIT : Ok as I'm new and I'm very lost, I need some more explanation.</p> <p>The Different steps are : 1) Activity create a listView, a custom CursorAdapter and a cursor, on the onCreate(). Then still on onCreate, it feed the cursor with a standart request on SQLiteDatabase object. Then we affect the cursor to the adapter, and the adapter to the listView.</p> <p>2) When an insert event comes, I use an insert function of SQLiteDatabase and then get the result of the request on a cursor, and give it to the CursorAdapter of the list (will it automatically update the listview ?)</p> <p>3) For my customAdapter well ... The more I read sources, examples and tutorial, the more I get lost. Just understood that I have to override bindView() and newView(), I didn't really get their purposes, plus the way I want to create many data type for my adapter...</p> <p>I feel like I'm not really smart, but I really tried and I'm still lost :(</p>
