chronometer

问题 I want a new activity to start when a new activity is reached, so far i've been having some trouble. This is what i have so far. I hope you guys understand what i am trying to do. If there is an easier way that works please tell me. perhaps i should put this in a thread? Chrono = (Chronometer) findViewById(R.id.chronometer1); Chrono.start(); while (!(Chrono.equals(chronoText))) { chronoText = Chrono.getText().toString(); if (chronoText.equals("00:30")) { Intent intent = new Intent

问题 How to start the chronometer with a specific time other than default 00:00? Is it possible to set chronometerObj.setBase(startTime) ? ch.setBase(SystemClock.elapsedRealtime()-anylongvalue); ch.start(); can I set start time, if I put anylongvalue? 回答1: In general: mChronometer.setBase(SystemClock.elapsedRealtime() - (nr_of_min * 60000 + nr_of_sec * 1000))) 回答2: Chronometer object, when instantiated, defaults to the base time being set to now ('now' as in the value you get from SystemClock

问题 I have an application in which I'm displaying a chronometer to the user for what he's doing. Whenever the activity goes to the background (wether by home button, or back) I save that time (in seconds) and when the activity is brought back, I want to continue the chronometer running from the same time. The user might select a different item from the list, and the time is different, and also he might turn off the phone... I can save the time of the chronometer, however I can't set it with a

问题 I am trying to completely restart Chronometer and its does not work. Instead it is being paused. Basically what I am trying to do is to do something while chronometer is counting till 10. After its done we prompt the user to try again. In which case we want to redo the count from 1 to 10 sec. But the Chronometer starts from the paused time instead of starting 0. here is the code: _cutOfTime = 10; // constant every time button is pressed do startRecording() it should always initiate the

问题 I am triying to add Chronometer inside service and fetch value.But i am not getting correct Chronometer value. public class NewLocationUpdateService extends Service { Chronometer chronometer; private static final int LOC_API_CALL_INTERVAL = 60 * 1000; @Override public int onStartCommand(Intent intent, int flags, int startId) { chronometer = new Chronometer(NewLocationUpdateService.this); chronometer.setBase(SystemClock.elapsedRealtime()); chronometer.start(); startTimer(); return START_NOT

问题 Is there a way by which using the android chronometer class to set base of the chronometer in 15 minutes and from that period the times goes down until 0 seconds? I have tried with setBase(60000) but this isn't work. 回答1: In general the chronometer works like this (if you would like to set the Base to a specific nr): mChronometer.setBase(SystemClock.elapsedRealtime() - (nr_of_min * 60000 + nr_of_sec * 1000))) what you are asking can be done through a countdown (http://developer.android.com

问题 I have a chronometer in Mainactivity.java I wanted to save the starting time using SharedPreferences and get the starting time show it in another activity but I can't figure out how to do so .I've tried Service which allows it running in the background but it failed as it can't pass the variable to another activity and people suggested using SharedPreferences would be easier. So does anyone knows how to save the starting time and get the value in another activity? Here's the code.

问题 My code never enters the onChronometerTick method. What am I doing incorrectly? Do I need to set the tick time somehow? I can't figure out a way to do that. elapsedTimer.setOnChronometerTickListener(new Chronometer.OnChronometerTickListener() { @Override public void onChronometerTick(Chronometer chronometer) { countUp[0] = (SystemClock.elapsedRealtime() - chronometer.getBase()) / 1000; elapsedTimeDynamic.setText("" + countUp); } }); elapsedTimer.start(); 回答1: For anyone in the future who is

问题 I've created an app that has a toggle button to start and stop a Chronometer, like a stop watch. When you first press the toggle button (executes .start() ), the chronometer will start counting, when you then press the button again (executes .stop() ), the chronometer appears on screen to stop counting as it should but when it is then started again it shows that it's actually still been counting in the background and shows the time on screen as if it was never stopped code: tglStartStop

问题 This question already has answers here : Android application restarts on orientation change (5 answers) Closed 5 years ago .
