Question

I have this method:

        public void onClick(View v) {
            if (test != true) {
                test = true;
                start = System.currentTimeMillis();
                end = System.currentTimeMillis() - start;
                DateFormat df = new SimpleDateFormat("HH 'hours', mm 'mins,' ss 'seconds'");
                df.setTimeZone(TimeZone.getTimeZone("GTM+0"));  
                tv.setText(df.format(new Date(end)));
            } else {
                DateFormat df = new SimpleDateFormat("HH 'hours', mm 'mins,' ss 'seconds'");
                end = System.currentTimeMillis() - start;
                df.setTimeZone(TimeZone.getTimeZone("GTM+0"));  
                tv.setText(df.format(new Date(end)));

            }

I would like to have the “tv” variable keep outputting the time value, without stop after the “else” statement – so I will always see the current value of the time.

I have try to make a loop through a boolean, but without success.

Answer 1

I highgly recommend using a Handler for the job.

Having already answered this question before, you may find my answer here. It’s a complete program.

Good luck.
