How to get a string back from AsyncTask?

Question

I have the following class:

public class getURLData extends AsyncTask{

@Override
protected String doInBackground(String... pa         


        

Answer 1

Add a context parameter to task's constructor which would refer to object where you'd store resulting data.

class PopulateArray extends AsyncTask>
{
    Context _context; // context may be what ever activity or object you want to store result in
    PopulateArray(Context context)
    {
        _context = context;
    }
    @Override
    protected ArrayList doInBackground(Integer... integers)
    {
        ArrayList data = new ArrayList();
        //manipulate
        return data;
    }

    @Override
    protected void onPostExecute(ArrayList strings)
    {
        _context.setData(strings);
    }
}
