On mobile devices, the DOUBLECLICK attribute defines the action to
        fire when a row is tapped.
        By default, no action is fired on mobile devices when the user taps on a row. To fire a
dedicated action, add the 
DOUBLECLICK attribute to the 
DISPLAY
ARRAY dialog and define an 
ON ACTION action
handler.
DISPLAY ARRAY arr TO sr.*
        ATTRIBUTES( DOUBLECLICK=row_select )
   ON ACTION row_select
      CALL process_row(arr_curr())
...
 
Alternatively, you can add a 
DOUBLECLICK attribute to your
TABLE definition in your form file.
Tip: We recommend you specify the
DOUBLECLICK attribute with the DISPLAY ARRAY dialog, as it is
strongly related to the DISPLAY ARRAY dialog.
 
Note: 
- On Androidâ„¢ devices, a long tap on a row only selects the row. The DOUBLECLICK
action is not fired.
 
-  For iOS devices, consider using list view decoration options, as described in Row configuration on iOS devices.
