How to refresh 2nd activity after intent from 1st activity

Question

Hi I want to refresh the list after moving from 1st activity to 2nd activity. I have tried many other ways like recreate() but that is not working for me.

I have used Intent in my 1st activity and onResume on 2nd activity, which is not working for me.

1st activity.

Intent i = new Intent(SaleOrderDetails.this,SalesOrders.class);
            startActivity(i);
            finish();

2nd activity

 @Override
    protected void onResume() {
    clearList();
    retrieveSalesOrder();
    super.onResume();
}

 public void clearList(){
    searchedSaleOrder.clear();
    saleOrderModelForDrafts.clear();
    saleOrderModelForConfirms.clear();
    saleOrderModelForCancels.clear();
    saleOrderModelForFullfilments.clear();
    readyForShippment.clear();
    readyToPickUp.clear();
}

Whenever we intent to the activity it should refresh.

Answer 1

 @Override
  protected void onResume() {
  super.onResume();
  clearList();
  retrieveSalesOrder();
}

 public void clearList(){
  searchedSaleOrder.clear();
  saleOrderModelForDrafts.clear();
  saleOrderModelForConfirms.clear();
  saleOrderModelForCancels.clear();
  saleOrderModelForFullfilments.clear();
  readyForShippment.clear();
  readyToPickUp.clear();
}

Use clearlist after super();
