chronometer

问题 I'm trying to start the chronometer in a new notification but from a paused(elapsed) "the elapsed time is got from another chronometer", not from zero The start base in Notification RemoteViews.class of chronometer is different from the start base in Chronometer.class it has different calculations Notification notification = new NotificationCompat.Builder(getApplicationContext()) .setSmallIcon(R.mipmap.ic_launcher) .setContentTitle(songName).build(); notification.contentView =

问题 I want to change the font of my chronometer in android.I have set my default font to be a custom font . The font seems to be applied every where except the chronometer. I have also tried setting android:fontFamily="@font/myfont" but it didn't work. Though the font appears to be applied in the preview window, but it doesn't change when i run my app on my device. Any idea to get over it ? Here's my code: <Chronometer android:fontFamily="@font/linotte_semibold" android:id="@+id/audio_player

问题 I have an application that has a chronometer, I need to set the start time to a difference between to dates How can I do that? 回答1: One way of doing this is to extends the Chronometer class... something like this: public class MyChronometer extends Chronometer { public int msElapsed; public boolean isRunning = false; public MyChronometer(Context context) { super(context); } public int getMsElapsed() { return msElapsed; } public void setMsElapsed(int ms) { setBase(getBase() - ms); msElapsed =

问题 I'm trying to implement a time counter (counts up from 0) which basically gets the saved time variable (startTime, which was created as soon as the user tapped a button) and subtracts the current time (Calendar.getInstance() maybe?) so that the result is the difference (in HH:MM:SS) between the two times. This method will be run on every tick of a chronometer so that the text view will be updated every second, effectively creating my timer. Now, I take this roundabout route because it's the

问题 I have a following chronometer implementation. I'd like to use it inside Service then sent its output to my fragment. The problem is that Service has no findViewById() because obviously it has no View at all. Is there any way I can get the chronometer to work inside Service and if not what can I use instead? code: Chronometer chronometer = (Chronometer) findViewById(R.id.chronometer); chronometer.setBase(SystemClock.elapsedRealtime()); chronometer.setOnChronometerTickListener( new Chronometer

问题 I knew the format of chronometer can be MM:SS or HH:MM:SS, but I want to know how to use setFormat() and getFormat() to set HH:MM:SS pattern(now is MM:SS). At this time, I use: android:format="@string/chronometer_initial_format" to set Format by declare: <xliff:g id="initial-format">%1$s</xliff:g> at res/values/strings.xml I tried to search by googling, but can't get good answer. Anyone can suggest ? Thank you 回答1: From http://developer.android.com/reference/android/widget/Chronometer.html

问题 I've developed an own implementation of a Chronometer. I did the follow: Create a Service (CronoService), that use a Runnable object that execute the thread. The Runnable will loop each 0.1 secs. Messenger Object that will receive messages from Ui to Start, Pause or Resume the Chronometer. Intent that will broadcast the time after each loop of the Runnable object. The code is: public class CronoService extends Service { public static final int PARAR = 0; public static final int EMPEZAR = 1;

问题 What I want is to measure time with milliseconds, but using Chronometer has the problem that it has no accuracy (its most resolution is seconds) I've seen this: Show miliseconds with Android Chronometer But I haven't been able to make it work. Maybe I should use another Object? Any idea? 回答1: Ok, this is the easiest way: When you want to start the chrono: StartTime=System.currentTimeMillis(); // I've defined StartTime as a double Then, you just have to do compare current time with StartTime:

问题 I have a chronometer timer on a fragment and I want it to reset to 00:00 and stops when I press a button. Here is the code of the fragment: public class FirstFragment extends Fragment { Chronometer chronometer; @Overried public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { final View view = inflater.inflate(R.layout.fragment_memo, container, false); Button testButton = view.findViewById(R.id.btn_test); chronometer = view.findViewById(R.id.stop

问题 I have implemented a simple chronometer from the android api demo. Now is it possible to show the countdown in chronometer like setting the start to 01:23 then onClick of start button, it will change to 01:22 then 01:21 and so on... till 00:00. Please let me know if anyone did it before. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ChronometerDemo.html Thank you. 回答1: For those who are interested, take a look at CountDownTimer class. Example: new
