Help with onClickListener on PhysicsLayout child view

[edunuzzi]

Hi, my name is Eduardo and i have been trying to figure out a way to set a onClickListener on a PhysicsLayout child view to change its background color. The thing is, when i do, all the physics behaviour stop working. Do you have any suggestions that could help me?

Sorry if this is a obvious question, i am just starting android developing :P

Hi,
i had the same problem. The onClickListener is obliviously interfering with the touchListener of the library, so i guess you can't have both. Fortunately you can use the touchInterface provided by the PhysicsLayout library. Just use the "touchEvents" to identify a click yourself. One way could be to track the time difference the user grabbed and released an item. If its shorter than a certain threshold its considered a click. To improve this you could also track the position of the grab and release and if it exceeds a certain distance its not a click anymore. I hope this helps.

physicsRelativeLayout.getPhysics().setOnFlingListener(new Physics.OnFlingListener() {

            private static final int clickTimeDeltaInMs = 150;
            private long grabStarTime = 0;

            @Override
            public void onGrabbed(View view) {
                grabStarTime = Calendar.getInstance().getTimeInMillis();
            }

            @Override
            public void onReleased(View view) {
                final long grabReleaseTime = Calendar.getInstance().getTimeInMillis();
                if((grabReleaseTime - grabStarTime) > clickTimeDeltaInMs) {
                    System.out.println("no click");
                    return;
                }

                 //do stuff – its a click
            }
});
