Hello, i have problem with using this code:
developer.android.com/guide/topics/ui/layout/listview.html
I used the code, everything same, but i had error at this part:
getLoaderManager().initLoader(0, null, this);
This is exception. It has problem with "this":
(MainActivity looking like: public class MainActivity extends ListActivity
implements LoaderManager.LoaderCallbacks<Cursor>)
Error:(71, 27) error: method initLoader in class LoaderManager cannot be
applied to given types;
required: int,Bundle,LoaderCallbacks<D>
found: int,<null>,MainActivity
reason: cannot infer type-variable(s) D
(argument mismatch; MainActivity cannot be converted to LoaderCallbacks<D>)
where D is a type-variable:
D extends Object declared in method
<D>initLoader(int,Bundle,LoaderCallbacks<D>)
Okey, so i tried to make new loader like:
android.app.LoaderManager.LoaderCallbacks<Cursor> loader = new
android.app.LoaderManager.LoaderCallbacks<Cursor>() {
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
return new CursorLoader(getApplicationContext(),
ContactsContract.Data.CONTENT_URI,
PROJECTION, SELECTION, null, null);
}
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
mAdapter.swapCursor(data);
}
public void onLoaderReset(Loader<Cursor> loader) {
mAdapter.swapCursor(null);
}
}
And used "loader" instead of "this" (initLoader(0, null, loader)), but i
wasnt working too, because of incompatibilty Loader<Cursor> and CursorLoader
in:
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
return new CursorLoader(getApplicationContext(),
ContactsContract.Data.CONTENT_URI,
PROJECTION, SELECTION, null, null);
}
Please, can someone help me with solving this problem?
Thanks very much, Sebastian :)
