Question

In my android application, first activity calls REST API to get the list of items using credentials. Now on clicking on any item, item id is passed and second activity is called using intent. This second activity calls the REST API using passing id and shows the list of sub items for that id.

I am using Progress Dialog in first activity. This is working fine. I want this progress dialog also continue in the second activity until sub item list does not display.

Presently progress dialog disappear as the second activity start and a blank screen appears until the sub list does not fetch.

Can anybody guide me how can I continue progress dialog in second activity and dismiss when sub list appears.

Answer 1

There are two options you can use:

1. You can stop the dialog when the first Activity is dismissed and then show it again in the onCreate method on your second Activity. As AkashG mentioned in the comments.
2. If you really want the dialog to be shown during the transition to the second Activity, you can use one single Activity instead of two and change the layout of that Activity to use the layout of the second Activity instead of calling another Activity. However, this can be complicated since you will implement the features of your two Activities into a single one.
