Question

how can i get the value of a counter counting down?

I’ve been trying with sg like this, but it has a problem with the type:

counter = new MyCount(10000,1000);
                  String secs;
                  secs=counter.toString();
                  if (started == false)
                  {
                      counter.start();
                      started = true;
                     switch (secs) {
                      case 8000: 
                            tv3.setTextColor(Color.RED);
                            break;
                      case 3000: 
                            tv3.setTextColor(Color.BLUE);
                            break;

                     }

                  }

Update:

MyCount is declared as MyCount counter;

I have also this code:

`public class MyCount extends CountDownTimer{
        public MyCount(long millisInFuture, long countDownInterval) {
        super(millisInFuture, countDownInterval);

        }
    @Override
    public void onFinish() {
         tv  = (TextView)findViewById(R.id.TextView01);
        tv.setText("Time is up!");
    }`

I put the switch part here:

@Override
        public void onTick(long millisUntilFinished) {
        tv.setText("" + millisUntilFinished/1000);
         switch (millisUntilFinished) {  //here is the problem
            case 8000:
                tv3.setTextColor(Color.RED);
                break;
            case 3000:
                tv3.setTextColor(Color.BLUE);
                break;
            }
    }

It had a problem with the switch parameter: “Cannot switch on a value of type long. Only convertible int values or enum constants are permitted“

That is way I have changed that line to switch ((int)millisUntilFinished/1000) { and changed to case lines to case 8: and case 3:.

Thank you!

I don’t know what is MyCount, but I see the error. Variable secs has type String, but you are trying compare it with the integers (3000, 8000). You can’t use String variables in the switch block. You need use there integer variable or, if counter has String type, use something like this code instead of the switch block:

if ("8000".equals(secs)) {
    tv3.setTextColor(Color.RED);
} else if ("3000".equals(secs)) {
    tv3.setTextColor(Color.BLUE);
}

Upd: If you use subclass of the CountDownTimer, you need to define onTick() callback in the MyCount class, like this:

@Override
public void onTick(long millisUntilFinished) {
    switch (millisUntilFinished) {
    case 8000:
        ...
        break;
    case 3000:
        ...
        break;
    }
}
