Date format of milliseconds shows SSS only-CodePudding

I'm trying to get the current time including milliseconds, but it only shows SSS.

Here is my code:


import android.text.format.DateFormat
import java.util.Calendar
...

String.format(
    "%s IOException: %s",
    DateFormat.format("HH:mm:ss.SSS", Calendar.getInstance().time),
    ex.message
)

It outputs 20:41:03.SSS some other text. Also tried just toasting the date, same output.

CodePudding user response：

Well you can't get milliseconds with DateFormat, you need to use SimpleDateFormat, so your code should look like this:

String.format(
    "%s IOException: %s",
    SimpleDateFormat("HH:mm:ss.SSS", Locale.getDefault()).format(Calendar.getInstance().time),
    ex.message
)

and also you could use Date() instead of Calendar.getInstance().time

String.format(
    "%s IOException: %s",
    SimpleDateFormat("HH:mm:ss.SSS", Locale.getDefault()).format(Date()),
    ex.message
)

Use the below code, it should work

import android.text.format.DateFormat
import java.util.Calendar
...

String.format(
    "%s IOException: %s",
    new SimpleDateFormat("HH:mm:ss.SSS").format(Calendar.getInstance().time),
    ex.message
)
