Apps Extending Thread

[Deleted User]

Hi,

I have a class I've created that extends Thread. This class calls a web service that returns a bunch of data. I'd to populate a member variable back in my Activity with this data as well as update the list on the Activity with this data. How can I achieve this? I've found an example to do it if you define the thread in the Activity class, but I have a separate file that extends Thread here. Could I get some assistance?

Thank you

You can only update GUI widgets in the GUI thread. So your other non-GUI thread needs to send a message back to the GUI thread through a Handler.

You create a Handler in the GUI thread and pass it to your non-GUI thread. Your non-GUI thread can then send messages back to the GUI thread, and that can respond by updating widgets as required.
