android button starts 2 timers

Question

I want to start 2 countdown timers when pressing one start button. When pressing start, maxTimer is set to the value of minTimer and they both count down with the same value. How do I seperate the 2? I need a countdown function for both minTimer and maxTimer.

Answer 1

you need to create 2 CounterClass timers...

final CounterClass timer = new CounterClass(minTid, 1000);
  final CounterClass timer2 = new CounterClass(maxTid, 1000);
        tv_start.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                timer.start();
                timer2.start()
            }




    });
        tv_stop.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                timer.cancel();
                timer2.cancel()

            }

        });
    }
