Default setup uses white fragment with white fingerprint icon about xamarin-fingerprint

[smstuebe]

I'll make it completely customizable like NegativeColor. Or better: I may add a styling mechanism, so you don't have to create a custom just class for styling.

So I finally got the time to upload my implementation that allows me use my custom xml layout, reference widgets from the layout in my extended FingerprintDialogFragment => "ZetagikCustomFingerprintDialogFragment" and even change the dialog type to "BottomSheetDialog".
Also, don't forget to modify your MainApplication.cs to use this customised FingerprintDialogFragment.

Hope this answers the questions related to customisations and @smstuebe accepts my PR since it modifies only the sample project and can serve as a guide for others too hopefully.

Well I took a stab at tinting your image and it seems to work. For anyone else...

public class CustomFingerprintDialogFragment : FingerprintDialogFragment
{
    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        var view=base.OnCreateView(inflater, container, savedInstanceState);

        var image = view.FindViewById<ImageView>(Resource.Id.fingerprint_imgFingerprint);
        image.SetColorFilter(Color.ParseColor("#000000")); // black 
            
        return view;
    }
}

I know we can create a custom Fragment, but I'm not sure how that works within your plugin.

See the documentation: https://github.com/smstuebe/xamarin-fingerprint#configuration

public class MyCustomDialogFragment : FingerprintDialogFragment
{
    public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        var view = base.OnCreateView(inflater, container, savedInstanceState);
        var image = view.FindViewById<ImageView>(Resource.Id.fingerprint_imgFingerprint);
        image.SetImageResource(Resource.Drawable.fingerprint_black);
        return view;
    }
}

Unfortunately, the fragment is calling ClearColorFilter() after each animation. That's why you have to add a black copy of the icon to your project.

I'll change the code, so you will be able to set a tint for the icon in the next release.

@smstuebe any update on this?

Hi @ChaseFlorell,

I'm the friendly issue checker.
Thanks for using the issue template 🌟
I appreciate it very much. I'm sure, the maintainers of this repository will answer, soon.

[ChaseFlorell]

That would be pretty cool @smstuebe. For now my workaround will do just fine.

[smstuebe]

Sure? have you tested a negative try where the icon turns red and then back to white? I'd be suprised, if it turns back to black.

Btw: don't close it. It contains a new feature request ^^

[ChaseFlorell]

ah, you are right. If I scan the correct finger, it goes green then disappears (thats what I tested). When I use the incorrect finger, it goes red then goes white.

[ChaseFlorell]

Not sure I can submit a PR, but here's my thought.

        private async Task AnimateFailedTryAsync()
        {
            if (_icon == null)
                return;
            var originalColorFilter = _icon.ColorFilter;
            _icon.SetColorFilter(NegativeColor);
            var shake = ObjectAnimator.OfFloat(_icon, "translationX", -10f, 10f);
            shake.SetDuration(500);
            shake.SetInterpolator(new CycleInterpolator(5));
            await shake.StartAsync();
            _icon.SetColorFilter(originalColorFilter);
        }

Hey guys, was this fixed?
I'm having a hard time on my app with the white on white...

[smstuebe]

oupsi, no. I'll move it to Milestone 1.4.6.

[ruisilva450]

As of now there is a way that I can apply my own FingerprintCustomDialog.axml?
If I do that in the OnCreateView it will lose the bindings even if I use the same resource ids that you use in your .axml file.

[marualderete]

@smstuebe is there any way to customize the text color of "Cancel" button? It is taking native color right now.

Kind regards

You can do this =>

public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
return inflater.Inflate(Resource.Layout.some_xml_file, container, false);
}

Thank you for the answer! Could you please give an example? Because Im really stuck at this point

[georgeharnwell]

I could do with some examples on this. I can only seem to find the background property to update. Not text color.

I found how to change background color, that was pretty simple, but text color changing looks really complicated. If you could help, I would be very grateful

[georgeharnwell]

That is NICE! Thank you!

[Bogenbai]

@alvynfash you are just... wizard.
Thank you so much
