How do I set a default time to my timepicker?

I have I time picker in my code and when I press the edit text it shows up and everything looks good but I want to set a default time for my time picker so when the user opens the time picker it will be shown a specific time like "3:34 am" as a default time for the user, how can I do that?. Any help will be appreciated. { you can use java and kotlin}

My time picker

private fun showTimePicker() {
    picker = MaterialTimePicker.Builder()
            .setTimeFormat(TimeFormat.CLOCK_12H)
            .setHour(12)
            .setMinute(0)
            .setTitleText("حدد الموعد الذي تريدة")
            .build()

    picker.show(supportFragmentManager, "AdhanNotifacations")
    picker.addOnPositiveButtonClickListener {
        if (picker.hour > 12) {
            fajrEditTxt.setHint(String.format("%02d", picker.hour - 12) + ":"
                    + String.format("%02d", picker.minute) + " PM")
        } else {
            fajrEditTxt.setHint(String.format("%02d", picker.hour) + ":"
                    + String.format("%02d", picker.minute) + " AM")
        }
        calender = Calendar.getInstance()
        calender[Calendar.HOUR_OF_DAY] = picker.hour
        calender[Calendar.MINUTE] = picker.minute
        calender[Calendar.SECOND] = 0
        calender[Calendar.MILLISECOND] = 0
    }
}

I'm not understanding what it is you're asking, but if you're trying to sort the times in the library, you could place the times in a list and then sort the list, or if you just want to compare the magnitude values of two different times with just a couple of lines of code, you could remove the time separators from the time strings, convert those values to numbers ( of your choice ) and compare. The numbers generated from the conversions have no real world values, but their magnitudes with respect to one another will always be valid.

Oh. Snippet editor does not support touch devices.

Ok then.

String time = "00:00";

  time.replace( ":", "" );

  Double d = Double.parseDouble( time );

So now you can do with d as you wish. As you can see you don't have to bother with whether any of the values are to great. If you're dealing with a pair of valid times it's their relative magnitudes that matters. Of course if the time is in 12 Hr format, you'll need to strip the time modifier ( A, a, P, p, Am, AM .... ) too.

You were almost there, just change the value of setHour and setMinute to the hour and minute you want respectively.

I made few changes to your code to show default time of 3:34am:

picker = MaterialTimePicker.Builder()
    .setTimeFormat(TimeFormat.CLOCK_12H)
    .setHour(3) //3 hour
    .setMinute(34) //34 minutes, so 3:34am
    .setTitleText("حدد الموعد الذي تريدة")
    .build()

If you want to show hour in PM, just add 12 to the hour. For example:

setHour(15)// will show 3pm

Let me know if you have any questions. Thanks.

EDIT

If you want to show time in strict HH:MM format you can keep your code and go as-is. But if you do not wish to be strict, then use the following code:

For example, this will show 9:3PM instead of 09:03PM.

//removed unnecesarry String.format
if(picker.hour > 12){
    fajrEditTxt.setHint((picker.hour - 12).toString() + ":" + (picker.minute).toString() + " PM")
}else{
    fajrEditTxt.setHint((picker.hour).toString() + ":" + (picker.minute).toString() + " AM")
}

OP asked how to access time:

val time = if(picker.hour > 12){
    String.format("%02d",picker.hour - 12) + ":" + String.format("%02d", picker.minute) + " PM"
}else{
    String.format("%02d",picker.hour) + ":" + String.format("%02d", picker.minute) + " AM"
}
time //use time, its in HH:MM format
fajrEditTxt.setHint(time)
