I'm still working in a solution to support correctly other devices like tablets, my first thought contemplate using the dimens still not sure if it is gonna be a dirty but quick fix

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        
        //I rather using a list, this way handling providers is separeted from the login methods
        List<AuthUI.IdpConfig> providers = Arrays.asList(
                new AuthUI.IdpConfig.EmailBuilder().build(),
                new AuthUI.IdpConfig.GoogleBuilder().build(),

                        .createSignInIntentBuilder()
                        .setAvailableProviders(providers)                        
                        .setTheme(R.style.LoginTheme)
                        .setLogo(R.mipmap.logo)

hey @cutiko, thanks for this great code!
however,am facing a slight problem . i have a dark background on my login and so if user enters no password while signing up, it shows a red color text saying "this field cannot be empty" the problem is the shade of red is too dark to be clearly visible, so i wanted to change it.I tried

    <item name="colorError">#ffb5b5</item><!--not working-->

but this isn't working.also i wanted to change this 'eye' color (the icon that is shown on the password's edit text which,when clicked, makes the password visible.
Any Suggestions??

<ps: am new to github so if this is a wrong place to comment then am sorry. >

setProviders is deprecated, any updates on new method ?

@guilmarc,

use setAvailableProviders as shown in the documentation.

Wow! Sorry for not replying, wasn't aware of the comments, I'm gonna pay more attention from now on

Thank you 👍 😄

@cutiko Do you mind if I write a medium blog on this and use parts of the gist for reference?
Thanks!

@the-dagger not all, please!

Again! Sorry for not replying but this doesn't send any notifications :(

[EDIT] There is no feature for this and there is even a change.org pledge for notifications on gist comments, found a solution GistWatch

How to bring the Sign in Button at the bottom of the screen

@mandar10 I don't think you can because each button is added programmatically inside a LinearLayout.

You can see the Activity here jump to line 130

And you can see the layout here.

In any case, I would try by aiming at the button style, by example, this is the email button. So by creating in your own styles a style="@style/FirebaseUI.Button.AccountChooser.EmailButton" you would override what is set by the library. Give it a try and let us all know.

@guilmarc update as requested, add some extra sugar I think is more handy for providers

@chaostools you can't change the eye icon color because is set programmatically, so even if you set it to any other asset when is clicked is gonna be set to a color from java.

TextInputLayout which is the wrapper to get the floating hint for material design appearance takes colors from:

       <item name="colorAccent">@color/colorAccent</item>
       <item name="colorControlNormal">@android:color/white</item>
       <item name="colorControlActivated">@android:color/white</item>
       <item name="colorControlHighlight">@android:color/white</item>
       <item name="android:textColor">@android:color/white</item>
       <item name="android:textColorHint">@android:color/white</item>

So check the following layouts and see what styles are being used, create the same styles in your own styles.xml and move those values around until you tweak it:

Forgot Password

Check Email

Most probably start for this one: Register Email

thanks all of my friends for all these knowledge

This is awesome, thanks cutiko.

I'm looking for a way to get rid of the elevation on the toolbar, anyone knows how to do that on the FirebaseUI?
I was thinking on something like:

<item name="elevation">0dp</item>

@Mauratay this is old, you should look at this

https://github.com/cutiko/FirebaseUiAuth

Check out the PRs, there is 1 pending for updating to androidx in case the master gives you problems

thanks
