Android Question ACTION_POINTER_DOWN etc

SteveTerrell · Jan 22, 2014

In an Activity it is possible to use Activity.ACTION_DOWN etc. to compare with MotionEvent actions and avoid having to use the values for those actions.

How can this be done in a class?

Me.ACTION_DOWN does not work

You can pass the Activity object to a class. However it will be simpler to just use these constants instead:

B4X:

Private ACTION_UP = 1, ACTION_MOVE = 2, ACTION_DOWN = 0 As Int

As usual, thanks for the quick reply.

I now have a different question, but related to your answer.

If I store an instance of a class in a map or list will each stored instance include a set of the above constants (if I use the Private int approach)?

Yes. However unless you are storing more than 100k instances you shouldn't be worried about these 3 ints.

Only 3600 instances so no worries
