Today i was working with the PreferenceActivity where you can create you preference screen automatically with xml. Nice solution to not store and load your settings each time manually.
I missed a number picker widget. There are only a few you can use, as for example EditTextPreference or CheckBoxPreference. So i had no choice and made my own NumberPickerPreference widget, which i would like to share.
Here my GitHub Repository with further infos: https://github.com/leonardarnold/NumberPickerPreference
Feel free to fork me, star me or whatever.
