Send data from activity to fragment in Android

Question

I have two classes. First is activity, second is a fragment where I have some EditText. In activity I have a subclass with async-task and in method doInBa

Answer 1

Smartest tried and tested way of passing data between fragments and activity is to create a variables,example:

class StorageUtil {
  public static ArrayList employees;
}

Then to pass data from fragment to activity, we do so in the onActivityCreated method:

//a field created in the sending fragment
ArrayList employees;

@Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
         employees=new ArrayList();

       //java 7 and above syntax for arraylist else use employees=new ArrayList() for java 6 and below

     //Adding first employee
        Employee employee=new Employee("1","Andrew","Sam","1984-04-10","Male","Ghanaian");
        employees.add(employee);

      //Adding second employee
       Employee employee=new Employee("1","Akuah","Morrison","1984-02-04","Female","Ghanaian");
         employees.add(employee);

        StorageUtil.employees=employees;
    }

Now you can get the value of StorageUtil.employees from everywhere. Goodluck!
