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

Answer 1

Just maintain one flag in button onClick method as:

public boolean oneTimeLoadActivity = false;

    myButton.setOnClickListener(new View.OnClickListener() {
          public void onClick(View view) {
               if(!oneTimeLoadActivity){
                    //start your new activity.
                   oneTimeLoadActivity = true;
                    }
        }
    });
