LoaderManager with multiple loaders: how to get the right cursorloader

Question

To me it's not clear how to get the right cursor if you have multiple Loaders. Lets say you define two different Loader with:

getLoaderManager().initLoader(0,null,this);
getLoaderManager().initLoader(1,null,this);

then in onCreateLoader() you do different things depending on the id:

@Override
public Loader<Cursor> onCreateLoader(int id, Bundle arg1) {

    if (id==0){
               CursorLoader loader = new CursorLoader(getActivity(),
            MaterialContentProvider.CONTENT_URI,null,null,null,null);
    }else{
               CursorLoader loader = new CursorLoader(getActivity(),
            CustomerContentProvider.CONTENT_URI,null,null,null,null);
            };
    return loader;
} 

so far so good. But how to get the right cursor in onLoadFinished() because you don't get any id to identify the right Cursor for the right Cursoradapter.

@Override
public void onLoadFinished(Loader<Cursor> arg0, Cursor cursor) {


    mycursoradapter1.swapCursor(cursor);
    if(isResumed()){
        setListShown(true);
    }else {
        setListShownNoAnimation(true);
    }



}
//and where to get the cursor for mycursoradapter2

or am I wrong and this is the wrong way to get results for two different cursoradapter in one fragment.

Answer 1

The Loader class has a method called getId(). I would hope this returns the id you've associated with the loader.

Answer 2

Use the getId() method of Loader:

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    switch (loader.getId()) {
        case 0:
            // do some stuff here
            break;
        case 1:
            // do some other stuff here
            break;
        case 2:
            // do some more stuff here
            break;
        default:
            break;
    }
}
