TimePreference | Make your time ... as a preference

I am trying to bind data from the class to the view using [ngModel] on my form but keep getting this error. Any help would be appreciated. Thank you.

I am doing an app using the PreferenceFragmentCompat, and i need to add an option TimePicker to my prefs, but my app crashes when i click on this option.

Here's my code:

TimePreference:

I've gone over several stackoverflow posts, but have sadly not yet found something that works for me: I have a TimePreference that uses a timepicker. I believe due to my color scheme the numbers are not showing up (seems to be white on white): Screenshot of how it looks at the moment

I have tried to figure out how to influence the number colors through a style. No luck, but for some stackoverflow answers pointing to android:TimePickerStyleand similar which requires a higher API than what I have set (API 15). I've also tried to use a custom-layout, but I am not quite sure where best to call the layout in the TimePreference.class (or I happened on the right place, but had no luck either). I've also researched the possibility of the changing the clock-face color, but didn't get any further there either.

The TimePreference currently looks like this (no custom-layout implemented):

I am writing an application that requires user input at a set time everyday. In my preference fragment I use alarmManager.setRepeating to set the time at which a notification should be displayed. When the notification is opened it takes the user to where they can enter the input the app needs.

What happens however is the as soon as the notification time is set the notification fires. I know that in the documentation it says that if the time used in alarmManager.setRepeating is already past the notification will fire immediatly. I have tried setting the notification time hours in the future, and I have tried hardcoding the notification time to hours in the future. It always fires immediatly.

Any help would be greatly appreciated.

My Preference Fragment

Hello fellow hardworking friends!

I have a timer in my app that works perfectly. The user input for the time is from an alert dialog:

I am building a preferences / settings screen inside an Android AppCompatActivity. One requirement is a custom [DialogPreference][1] with a TimePicker.

The DialogPreference must be 'native', meaning not the compatibility version like described here and here.

The code for the AppCompatActivity:

I have the following code:

Double.valueOf(defaultValue.toString()).longValue()

I'm using this line to parse the defaultValue of a TimePicker I've created for Android. I'm setting the default value for this (in my PreferenceScreen xml) to be 1483318800000. For some reason, it starts off in scientific notation: 1.48331876E12 and then after running through the code above: 1483318760000. It ends up being off. I need it to be correct since this is a timestamp in milliseconds. I'm shooting for 8pm--but I can only ever get it to be 7:59pm (since after the conversion, it's off).

If I do Long.parseLong(defaultValue.toString()) then I'll get a NumberFormatException since it's in scientific notation.

How can I guarantee a "good" conversion?

Edit: The conversion code is the first line of code I'm showing above. I'm setting the default value like so:

I am currently trying to create a custom Preference with a Datepicker.

For that purpose I've found a tutorial.

Next to the xml, the first step was to create a class "TimePreference" which extends "DialogPreference".

The second class was "TimePreferenceFragmentCompat" which extends "PreferenceDialogFragmentCompat".
But in my Android Studio I can't find the "PreferenceDialogFragmentCompat" class.
Nor does import android.support.v7.preference.PreferenceDialogFragmentCompat; work.

Does someone know what I may am missing? Are there any new ways to do what i want to achieve? (I didn't found anything newer than this tutorial).

Thanks in advance!
