Android Question Dragging views

[Roger Daley]

Hi All

In reference to the examples in this thread. [PTD3.zip]

I have an App that has 4 panels each with multiple views. It also has views not on panels. I need to drag each panel by 1 of the views on that panel.
Originally I thought I needed to write a sub for each of the views that dragged the corresponding panel but the view_touch sub in the example [PTD3.zip] shows otherwise.

My question is how to best identify which view is touched and action appropriately?

Thanks in advance.
Regards Roger

Have you tried to use the Sender keyword to get the panel that raised the event?

Thanks Erel,

At the keyboard trying that as you typed. Your reply gives me confidence that I am on the right track.

Hi All,

I am still trying to drag panels without success. I have attached a simplified example of the App. The example has two panels with respective daughter views, the views cover the panels therefore dragging the panels is by touching/dragging on a daughter view.

So far the App/Example recognises the "Down" action but not the "Move" or "UP" actions.

Any help would be most welcome.

Regards Roger

The correct way to implement such a feature is with a class. This allows you to create multiple instances of the class.

See the DraggableView example: https://www.b4x.com/android/forum/threads/classes-are-soon-coming.18395/#content

Looked at the DraggableView example. Trying to understand it I loaded it, zip attached.
Obviously I am missing a library or libraries but could not find them.
I think I am missing more than libraries.

you need reflection lib. AND the class-module!!!
Looks like you added the class-code to an activity!?

Thanks DonManfred,
Reflection library OK. Back to the User Guide to read up on Classes.
