Question

I’ve looked everywhere for an answer but cannot find one for my situation. I have a couple problems and also wonder how to include millisecond countdown as well. I’m trying to get a countdown timer in the format 00.00 (seconds.milliseconds). A button is used to start the timer. The times I use depend on the button pressed, 5, 10, 15, 30, or 90 seconds. I’ll just says its hard coded to 5000 ms to make simpler for now.

long timeSecs = 5000; // really timeSecs is dynamic but for the sake of simplicity 
long countDownInterval = 1000; // this is a static value
TextView TVcountDown = (TextView)findViewById(R.id.TVcountDown);

public void createTimer() {

    new CountDownTimer(timeSecs, countDownInterval) {
        public void onTick(long millisUntilFinished) {
            TVcountDown.setText(millisUntilFinished / 1000); // error here on
//.setText unless I cast to an int, which all values are long so I'm not sure why
        }

        @Override
        public void onFinish() {
            TVcountDown.setBackgroundColor(R.color.solid_red); // error here
            TVcountDown.setTextColor(R.color.white);  // error here
            TVcountDown.setText("Expired"); // it will make it here
      // It doesn't count down, just goes straight to onFinish() and displays "Expired"
        }

    }.start();
}

Thanks in advance. I’ve been beating my head against the desk for awhile now.

Answer 1

Try this.
For setText

TVcountDown.setText("" + (millisUntilFinished / 1000)); 

For the color

Resources res = getResources();
TVcountDown.setBackgroundColor(res.getcolor(R.color.solid_red));
TVcountDown.setTextColor(res.getcolor(R.color.white));  

you should get color from the color resource before setting.
