How can I return an ArrayList from my AsyncTask?

Question

I have an AsynkTask method on my MainActivity that it\'s the following:

class chargeCars extends AsyncTask> {
              


        

Answer 1

Method 1: Don't use clone just use object to add:

protected void onPostExecute(ArrayList c)
{
       super.onPostExecute();
    for(Car cr: c)
    {
        totalCars.add(cr);
    }
       //Code for further execution
}

Method 2: Make a method which will be called by onPostExceute() after it has got ArrayList

 protected void onPostExecute(ArrayList c)
    {
     super.onPostExecute();
       setValues(c);
    }

private void setValues(ArrayList c){
      for(Car cr: c)
        {
            totalCars.add(cr);
        }
 //Code for further execution
}
