Question

I am using this datepreference picker:

https://mikeburnscoder.wordpress.com/2010/09/27/datepreference-an-android-library/

I start the picker in my preferences screeen via this code:

<com.Test.preference.DatePreference
            android:key="start_date"
            android:title="Start at"
            android:defaultValue="" />

This is working well. But I cannot find out how to set a default date.
Now it start with 1. Jan 1970. But I want it to set to current date.

I tried it via

android:defaultValue="12.09.2011" 

But this lets the app crash.

Answer 1

I have never set defaults of dates in xml. I assume that it is looking for a long value that represents the # of millis since 01/01/1970. So you’re going to need some long string of numbers.

here is an example : 1315868978

As for how you can default it to the current date and time. I don’t think you can do this from xml. But in your java you could use System.currentTimeInMillis(). That would like something like this prefs.getLong("time", System.currentTimeInMillis());

Edit: I missed the fact that you were using a library. When I follow your link it looks you you formated the default wrong”

<org.bostonandroid.datepreference.DatePreference
  android:key="dob" android:title="@string/dob"
  android:defaultValue="1991.01.01" />

You need to do year first, not last.
