How to start chronometer in reverse in android?

Question

cmtr.setText(finalTime);
cmtr.setBase(SystemClock.elapsedRealtime());

timetest = SystemClock.elapsedRealtime();
Log.d("SETTIME: ", ""+timetest);
cmtr.start();

eltime = SystemClock.elapsedRealtime();
Log.d("ELapsed: ", ""+eltime);

Note: i want to start my chronometer in reverse order. like i set chronometer 10 seconds. now, i want to start from 10 to 0 seconds in reverse order. so can anyone help to get this solution.? Thank you so much in advance.

Answer 1

You can't, the Chronometer widget only counts up, that's the specific purpose it was made for. If you want to count down, use the CountDownTimer (the Android SDK page contains a specific example where a TextView is updated), or roll your own solution.

These classes are trivial wrappers to save you some typing. You really shouldn't feel uncomfortable writing an alternative implementation if they don´t fit your exact needs.

[Update]

As Ronaldo Bahia added in the remarks, since API 24 the Chronometer actually offers this functionally through the setCountDown method.
