Listview test if I have selected a row

MIT App Inventor Help

Hello, I have a listview, I need to know if I have selected a row to perform some operations, can you kindly tell me how to do it. Thanks to all

If is not empty listview selection
Then // do process for true
Else // do process for false

But remember untill refresh the page once selected this will show true. So if you catch the selectiin jn a global variable then you can use it. And you can set the global variabke to clear

Put your code in the List View After Selecting event

Why do you try now select list item list?

Directly use listview section and not selection index.

If is empty not listview1 selection
