Lock for Android Custom Theming

The Lock.Android UI is very customizable.

Supported attributes list

Auth0.PrimaryColor color - reference Used as normal state in widgets like the Submit button. Also used as accent color.

A New Resource File

First you need to create a new Theme that extends from Lock.Theme, and override the attributes you want to customize.


  <style name="MyLockTheme" parent="Lock.Theme">
    <item name="Auth0.HeaderLogo">@drawable/com_auth0_lock_header_logo</item>
    <item name="Auth0.HeaderTitle">@string/com_auth0_lock_header_title</item>
    <item name="Auth0.HeaderTitleColor">@color/com_auth0_lock_text</item>
    <item name="Auth0.HeaderBackground">@color/com_auth0_lock_header_background</item>
    <item name="Auth0.PrimaryColor">@color/com_auth0_lock_submit_normal</item>
    <item name="Auth0.DarkPrimaryColor">@color/com_auth0_lock_submit_pressed</item>

Those attributes not overridden by the user will default to the ones defined in Lock.Theme.

Then, you need to tell the Manifest that you want to use the new MyLockTheme in the Activity. This is very important!!

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Pay Attention to the Manifest!

Please note that if you define your own Theme in a style resource file and forget to specify that the Theme's parent is "Lock.Theme", or you forget to tell the Manifest which will be the Theme for the Activity, you will end up with a really bad looking UI. This may also happen if the values you specify in your custom Theme are invalid.
