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

Use a flag variable set it to true, Check if its true just return else perform Activity Call.

You can also use setClickable(false) one executing the Activity Call

flg=false
 public void onClick(View view) { 
       if(flg==true)
         return;
       else
       { flg=true;
        // perform click}
    }
