My device is 5800 and the only navigation method is touch

but I do not know which event is touch event.

sometimes click event can be instead of touch event

such as click a button

but when your finger slide down or up on the screen to make the list scroll down or up, the click event can do nothing about it

Now, I hope someone can tell me how can I capture the event when user's finger slide up or down on the screen?

Thank you very much~~!
