How to prevent the activity from loading twice on pressing the button

Question

I am trying to prevent the activity from loading twice if I press the button twice instantly after the first click.

I have an activity which loads on click of a butt

I think you're going about solving the problem the wrong way. Generally it is a bad idea for an activity to be making long-running web requests in any of its startup lifecycle methods (onCreate(), onResume(), etc). Really these methods should simply be used to instantiate and initialise objects your activity will use and should therefore be relatively quick.

If you need to be performing a web request then do this in a background thread from your newly launched activity (and show the loading dialog in the new activity). Once the background request thread completes it can update the activity and hide the dialog.

This then means your new activity should get launched immediately and prevent the double click from being possible.
