CountDownTextView

A simple countdown widget and easy to use.

###Simple

###Usage

    compile 'com.ufreedom.countdowntextview:library:0.1.0'

You can give it a start time in the SystemClock.elapsedRealtime timebase, and it counts down from that.

By default it will not update the time value in text but give a callback onTick(),If you want to display the current timer value ,Please use setAutoDisplayText(true).

By default the display timer value is in the form "MM:SS" or "HH:MM:SS", you can use setTimeFormat() to use other format :

long timeInFuture = SystemClock.elapsedRealtime + 1000 * 60 * 20;//20 minutes

CountDownTextView countDownTextView = findViewById(R.id.countDownTextView)
countDownTextView.setTimeInFuture(timeInFuture);
countDownTextView.setAutoShowText(true);
countDownTextView.start();

###Callback

    public interface CountDownCallback {

        /**
         * Callback fired on regular interval.
         * @param millisUntilFinished The amount of time until finished.
         */
        void onTick(CountDownTextView countDownTextView,long millisUntilFinished);

        /**
         * Callback fired when the time is up.
         */
        void onFinish(CountDownTextView countDownTextView);
        
    }
