countdowntimer

问题 I have made a CountDownTimer that works perfectly - you can get the correct time for soft/medium/hard-boiling an egg. My problem is that the timer resets after orientation change. I have googled and tried so many solution, still I don't understand how to use the onSave and onRestore properly. Here's my code: Any tips? package com.dohman.boilaneggbae; import android.graphics.PorterDuff; import android.os.CountDownTimer; import android.support.v7.app.AppCompatActivity; import android.os.Bundle;

问题 I have this very simple app, where I am trying to implement countdown, Start and Stop functionality seems to be working fine but when I press Stop , the value of seconds is not updating in the view which is desired behaviour but when I observed console log, it it showing the value of sec continuously changing which I guess shows that setInterval is still running and not cleared.

问题 I know how to create a simple countdown timer in Java. But I'd like to create this one in Kotlin. package android.os; new CountDownTimer(20000, 1000) { public void onTick(long millisUntilFinished) { mTextField.setText("seconds remaining: " + millisUntilFinished / 1000); } public void onFinish() { mTextField.setText("Time's finished!"); } }.start(); How can I do it using Kotlin? 回答1: You can use Kotlin objects: val timer = object: CountDownTimer(20000, 1000) { override fun onTick

问题 This question already has answers here : Convert int (number) to string with leading zeros? (4 digits) [duplicate] (4 answers) Closed 6 days ago . I created a timer that returns the decreasing time: public static void timerIdle_Tick(object sender, EventArgs e) { if (tempo >= 60) { minuto = tempo / 60; segundo = tempo % 60; } else { minuto = 0; segundo = tempo; } segundo--; if (minuto > 0) { if (segundo < 0) { segundo = 59; minuto--; } } if (minuto == 0 && segundo == 0) { timerIdle.Stop();

问题 I made a CountDownTimer code, i would like to CountDownTimer restart when countdown finished even if app is closed, but it only restart if app running or when app is re-launched. So if i close the app when countdown is 00:10 (min:sec) and reopen the app after 30 sec, the counter should be 00:40, but it starts from 1 minute... But if i close app in 00:40 and reopen after 10 sec, it starts from 00:30 so its good, but the problem only with restart from 1 min when app closed.... can somebody help
