How to can convert Sting time value in 00:00:00 format?

I have one String
String time = 1 hour 37 minutes
How can I convert this time into 1:37:00 format in android?

1)first step remove space from string (string = "1 hour 37 minutes)
text = string.replace(" ", "");
2) Second step replace hour to ":" and minutes by ":00"
text = text.replace("hour",":");
text = text.replace("minutes",":00");

I guess you must code a function that format your string into what you need. Your function should be like this:
public static String formatTime(String inputTime)
{
String result = inputTime.replace(" ","");
result = result.replace("hours",":").replace("hour",":").replace("minutes","").replace("minute","");
String[] resultAux = result.split(":"); //First position will be hours, second position will be minutes
for(int i=0; i<resultAux.length; i++)
{
if(resultAux[i].length() == 1)
{
resultAux[i] = "0" + resultAux[i]; //If we have 1 character in minutes we put the 0
}
}
return String.join(":",resultAux) + ":00"; //Due to in your example you don't mention that you can have miliseconds we just put the miliseconds at the end
}
Of course you will call your function like this:
System.out.println("result is: " + formatTime("2 hours 37 minutes"));

Alive time in xamarin

I have this code:
int h = DateTime.Now.Hour;
int m = DateTime.Now.Minute;
int s = DateTime.Now.Second;
textTime.Text = h.ToString() + ":" + m.ToString() + ":" + s.ToString();
But this code is not alive.

I am not totally sure I understand your question, but maybe you want to use a StopWatch? You would need to "start" and "stop" it when necessary to get the elapsed time corrrect
var sw = new Stopwatch();
sw.Start();
sw.Stop();
var text = string.Format( "{0}:{1}:{2}", sw.Elapsed.Hours, sw.Elapsed.Minutes, sw.Elapsed.Seconds );

How to retrieve Youtube Video Length in android?

In my app i have youtube video url. Now how can i get the duration of video from that url?
I used this code but it doesn't work. Any other way to get the video duration?
MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource("https://www.youtube.com/watch?v=" + videoID);
String time = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
long timeInmillisec = Long.parseLong(time);
long duration = timeInmillisec / 1000;
long hours = duration / 3600;
long minutes = (duration - hours * 3600) / 60;
long seconds = duration - (hours * 3600 + minutes * 60);
Toast.makeText(this, "https://www.youtube.com/watch?v=" + videoID + "\n" + hours + " : " + minutes + " : " + seconds, Toast.LENGTH_SHORT).show();

if you have a youtube player instantiated with this id you can get the video duration from him.
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean wasRestored) {
if (!wasRestored) {
youTubePlayer.loadVideo(videoID);
this.youtubePlayer=youTubePlayer;
}
}
and then you can do
youtubePlayer.getDurationMillis()
to get total video's time. Note that it will return 0 when video is loading so you might need to watch the evolution of the value returned and wait for it.

How to get mp3 track duration without creating MediaPlayer instance? I just need to show mp3 song length in mp3 file list, so I think that I shouldn't create MediaPlayer object for each of tracks in the list
And another:
sometimes MediaPlayer returns wrong duration of the song ( I think its so because bitrate of those files is dinamic ). How can I get right duration of the song?

// load data file
MediaMetadataRetriever metaRetriever = new MediaMetadataRetriever();
metaRetriever.setDataSource(filePath);
String out = "";
// get mp3 info
// convert duration to minute:seconds
String duration =
metaRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
Log.v("time", duration);
long dur = Long.parseLong(duration);
String seconds = String.valueOf((dur % 60000) / 1000);
Log.v("seconds", seconds);
String minutes = String.valueOf(dur / 60000);
out = minutes + ":" + seconds;
if (seconds.length() == 1) {
txtTime.setText("0" + minutes + ":0" + seconds);
}else {
txtTime.setText("0" + minutes + ":" + seconds);
}
Log.v("minutes", minutes);
// close object
metaRetriever.release();

You can use the MediaMetadataRetriever to get the duration of a song. Use the METADATA_KEY_DURATION in combination with the extractMetadata() funciton.

Here is the Kotlin version:
var metaRetriever:MediaMetadataRetriever = MediaMetadataRetriever()
metaRetriever.setDataSource(filePath)
var out:String = ""
var txtTime:String = ""
var duration:String = metaRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION)
Log.d("DURATION VALUE", duration)
var dur:Long = duration.toLong()
var seconds:String = ((dur % 60000)/1000).toString()
Log.d("SECONDS VALUE", seconds)
var minutes:String = (dur / 60000).toString()
out = minutes + ":" + seconds
if (seconds.length == 1){
txtTime = "0" + minutes + ":0" + seconds
}
else {
txtTime = "0" + minutes + ":" + seconds
}
Log.d("MINUTES VALUE", minutes)
Log.d("FORMATTED TIME", txtTime)
metaRetriever.release()

If you want to support older Android versions, you can use a 3rd party library. For example http://www.jthink.net/jaudiotagger/ works fine, though it's relatively space consuming for an Android application (a little less than 1 MB).
True programmers would of course parse the duration from the binary file without using any libraries ;) I didn't have enough skill for this.

I found this more accurate getLength with FFmpeg
int soundLength = (int) new SoxController(context, new File(""), shell).getLength(soundPath);

Android rolling digital time display wanted

I'm looking for Android code to do a digital timer display that looks like one of the standard timers that came (I think) with some HTC phones. The timer look is different than most in that it uses digits but has a mechanical scroll wheel look, as if the numbers were painted on a roller. It does not mimic an LED timer nor does it mimic a mechanic "flip" type digital timer. It may need graphic files to work.
There is code on googlesource that seems it may have what I want. But I can't find any index that has images of the code running. And it is not always easy (for me) to get the code running so I can see what it looks like. Some code that looks promising is the following:

See http://code.google.com/p/android-wheel/
You might be able to adapt it for your needs.

Here's code provided by a previous user:
private Handler mHandler = new Handler();
OnClickListener mStartListener = new OnClickListener()
{
public void onClick(View v)
{
if (mStartTime == 0L)
{
mStartTime = System.currentTimeMillis();
mHandler.removeCallbacks(mUpdateTimeTask);
mHandler.postDelayed(mUpdateTimeTask, 100);
}
}
};
.........
private Runnable mUpdateTimeTask = new Runnable()
{
public void run()
{
final long start = mStartTime;
long millis = SystemClock.uptimeMillis() - start;
int seconds = (int) (millis / 1000);
int minutes = seconds / 60;
seconds = seconds % 60;
if (seconds < 10)
{
mTimeLabel.setText("" + minutes + ":0" + seconds);
}
else
{
mTimeLabel.setText("" + minutes + ":" + seconds);
}
mHandler.postAtTime(this,start + (((minutes * 60) + seconds + 1) * 1000));
}
};
