I am trying to implement LoaderManager since its taking a while to load the rows into my ListView. All of the examples I have found online keep referring to a CONTENT_URI - something which I don't have.
Here's my old code for loading my ListView content:
@Override
public void onCreate( Bundle savedInstanceState )
{
...
String path = "/sdcard/mytunesdb.sqlite"; // Warning, yes, I know..
db = SQLiteDatabase.openDatabase( path, null, 0 );
lvCustomList = (ListView) findViewById( R.id.lv_custom_list );
String[] columns = new String[] { "Name" };
// THE XML DEFINED VIEWS FOR EACH FIELD TO BE BOUND TO
int[] to = new int[] { R.id.lv_tune };
Cursor c = db.rawQuery( "SELECT rowid _id, Name FROM Tune ORDER BY Name", null );
cAdapter = new MySimpleCursorAdapter( this, R.layout.like_hate_row, c, columns, to, 0 );
viewBinder = new CustomViewBinder();
cAdapter.setViewBinder( (ViewBinder) viewBinder );
lvCustomList.setAdapter( cAdapter );
OK, so I start implementing the LoaderManager callbacks after changing the above code so that the cAdapter is created with null projection (null instead of 'columns' parameter). This is how I far I get.. How do I put my rawQuery into the onCreateLoader method?
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args)
{
String[] columns = new String[] { "Name" };
!!! HELP - I don't have a CONTENT_URI - my database is external - what do I put below?
CursorLoader cursorLoader = new CursorLoader( getActivity(),
TutListProvider.CONTENT_URI, columns, null, null, null);
return cursorLoader;
}
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor)
{
cAdapter.swapCursor( cursor );
}
@Override
public void onLoaderReset(Loader<Cursor> loader)
{
cAdapter.swapCursor( null );
}
Do I need to keep the URI code and implement a ContentProvider for my SQL database instead??
I figured this out with the help of SimpleCursorLoader mentioned in other StackOverlow posts. I have new problems, but at the below link you will find my solution.
