android - 计时器中的更新时间

Question

我有一个计时器。应该有时间显示。当我启动计时器时，时间始终相同，但它应该更新

调用:

                Log.e("XXX","OnClick");
                String[] array = clock.getText().toString().split(":");
                int ms = (Integer.valueOf(array[0])*60 + Integer.valueOf(array[1]))*60000;
                Log.e("XXX",String.valueOf(ms));
                MyTimer counter = new MyTimer(ms, 1000, Timer.this,clock);

                counter.start();

计时器:

public class MyTimer extends CountDownTimer {
    private Context con;
    private Chronometer clock;

    public MyTimer(long millisInFuture, long countDownInterval, Context context, Chronometer clock) {
        super(millisInFuture, countDownInterval);
        this.con = context;
        this.clock= clock;
        // TODO Auto-generated constructor stub
    }


    @Override
    public void onTick(long millisUntilFinished) {

        int seconds = (int) (millisUntilFinished / 1000) % 60 ;
        int minutes = (int) ((millisUntilFinished / (1000*60)) % 60);
        int hours   = (int) ((millisUntilFinished / (1000*60*60)) % 24);
        clock.setText( String.format("%02d:%02d:%02d", hours,minutes,seconds));
        Log.e("Timer", String.valueOf(millisUntilFinished));

    }

问题是计时器上的时间总是一样的。和日志(计时器)也不要出现。会不会是UI刷新太快了？

我不太确定将您的上下文和 View 作为扩展类的参数传递。也许您应该尝试对您的代码进行这种改编(并摆脱您的 MyTimer 类)？

Log.e("XXX","OnClick");
String[] array = clock.getText().toString().split(":");
int ms = (Integer.valueOf(array[0])*60 + Integer.valueOf(array[1]))*60000;
Log.e("XXX",String.valueOf(ms));

new CountDownTimer(ms,1000){
    @Override
    public void onTick(long millisUntilFinished) {

        int seconds = (int) (millisUntilFinished / 1000) % 60 ;
        int minutes = (int) ((millisUntilFinished / (1000*60)) % 60);
        int hours   = (int) ((millisUntilFinished / (1000*60*60)) % 24);
        clock.setText( String.format("%02d:%02d:%02d", hours,minutes,seconds));
        Log.e("Timer", String.valueOf(millisUntilFinished));

    }
}.start();
