Select from a list on Android

When your user taps on a button, the “result” of the call to
dialogGetResponse() is set to positive if the first button is tapped
or negative if the second button is tapped. In your code, you can check
the value of resp, which is a dictionary, and the which key is set to either
positive or negative.
A subsequent call to dialogGetSelectedItems() returns the index
value of the selected list item.

Index item 0

Index item 1

Index item 2

Index item 3

Index item 4

The “positive” button The “negative” button

So…if the positive button is tapped, you can index into the list of athlete names
to see which athlete was selected from the displayed list. The selected name can then
be sent to the web server to request the rest of the athlete’s data using the send_
to_server() function.

You can use this behavior in the next version of your code.
