AsyncTaskLoader

To use an AsyncTaskLoader, you need to implement ‘LoaderManager.LoaderCallbacks’ in your HistoryTabFragment. See an example here.

public class HistoryTabFragment extends ListFragment implements LoaderManager.LoaderCallbacks<ArrayList<ExerciseEntry>> {

//…

//…

//…

@Override
public Loader<ArrayList<ExerciseEntry>> onCreateLoader(int i, Bundle bundle) {
return new DataLoader(mContext); // DataLoader is your AsyncTaskLoader.
}

@Override
public void onLoadFinished(Loader<ArrayList<ExerciseEntry>> loader, ArrayList<ExerciseEntry> exerciseEntries) {
//Put your code here.
}

@Override
public void onLoaderReset(Loader<ArrayList<ExerciseEntry>> loader) {
//Put your code here.
}

}//end class

public class DataLoader extends AsyncTaskLoader<ArrayList<ExerciseEntry>> {
//Your code here.





public DataLoader(Context context) {




 //Your code here.




}
 
@Override




protected void onStartLoading() {




 forceLoad(); //Force an asynchronous load.




}
@Override
public ArrayList<ExerciseEntry> loadInBackground() {




 //Your code




}
 }//end class
