Android Question Menu calling dialog problem

[MartinR]

I find that if I call an input dialog from a menu item the pop-up keypad persists after entering the input and clicking OK. However, if I use a button to call the dialog the keypad disappears OK. There seems to be an issue of stability as well since I get the message that my app has stopped after repeated (perhaps a dozen or so times) use of the menu, but no such problem arises when using the button.

The code below illustrates the problem.

The actual app I am trying to develop allows the user to open a file via a menu. After successfully opening the file, getting the data, processing it and displaying the result the app almost always crashes/stops. However, if instead of the menu, I supply a button to allow the user to open the file all works fine.

Is there something extra I need to do to use menus? I would like to keep the display as free from buttons as possible so that the user can examine the information displayed.

I get no error reports via the log window indicating why the program crashes/stops.

The best solution is to upgrade to B4A 7 and use the new async dialogs.

You should call a different sub with CallSubDelayed from the menu click event and show the modal dialogs there.

Many thanks, Erel; CallSubDelayed seems to work OK.

Will also upgrade.
