如何调用在不同函数中定义的对象方法？ [Android]

Question

I have this function called startTimer and I created an instance of the CountDownTimer class:

public void startTimer(View view){

    CountDownTimer myTime = new CountDownTimer(30000,1000) {

    }

}

The CountDownTimer has a method called cancel() that I want to invoke from a different method, resetTimer():

public void resetTimer() {

}

Both functions are contained within a single class. How do I call the cancel() method of CountDownTimer from the resetTimer()?

Answer 1

Make myTime a private global variable (global here meaning "outside of any function"):

public class myClass {
    private CountDownTimer myTime = ...

    public void startTimer(View view) {
        myTime.start();
    }

    public void resetTimer() {
        myTime. //etc...
    }
}

Answer 2

private CountDownTimer myTime;

public void startTimer(View view){

    myTime = new CountDownTimer(30000,1000) {

    }
}

public void reset() {
    myTime.cancel();
}
