Account Kit advanced UI customizing

My default color is purple (#9b59b6) i want to change top title (blue) color to purple as well. I red manual on Customizing the Account Kit UI in Android Implemented style like this, but had no further luck changing top title color to purple.
//Delauft color: purple
UIManager uiManager = new SkinManager(SkinManager.Skin.CONTEMPORARY, ContextCompat.getColor(this, R.color.default_color), R.drawable.register_screen, SkinManager.Tint.WHITE, 0.1);
configurationBuilder.setUIManager(uiManager);
In my style.xml i have
<style name="AppBaseTheme" parent="android:style/Theme.Light.NoTitleBar">
<item name="colorPrimary">#9b59b6</item>
<item name="colorPrimaryDark">#9b59b6</item>
<item name="colorAccent">#9b59b6</item>
<!-- other elements-->
</style>
Other activities works fine.
I have app that look like this:
UPDATE
Solution: In AndroidManifest
<activity android:name="com.facebook.accountkit.ui.AccountKitActivity" android:theme="#style/CustomFbStyle" tools:replace="android:theme"/>
And in style.xml
<style name="CustomFbStyle" parent="Theme.AccountKit">
<item name="colorPrimary">#9b59b6</item>
<item name="colorPrimaryDark">#9b59b6</item>
</style>

Please check the theme you are using i.e Appbasetheme is the same which you have mentioned in application tag of manifest.
<application
android:label="#string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="#style/AppbaseTheme">
or you can also use specific theme to specific class by giving android:theme tag to that class in manifest

Android Lollipop Theme

I want a white EditText.
Which theme shall I use?
I can customize the rest of the looks.
I searched for any xml file also, to find which one could I use as the drawable background, but did not find one.
Can anyone suggest any xml or theme?
The EditText now is black.
I want it to be white colored and same design.
I.e.: just a line, not the braces at the end.
I have looked into the drawable folder of the API 22 SDK, but it did not help...
I got only One solution, but it gives the older EditTexts in white colour.
Like this one

In android manifest file apply the theme .
<activity
android:name="your activity name"
android:label="#string/app_name"
android:screenOrientation="landscape"
android:theme="#style/Theme.App.Base"
android:windowSoftInputMode="stateHidden|adjustPan" >
in the values-v14 folder change the style to below
<style name="Theme.App.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorControlNormal">#FFFFFF</item>
<item name="colorControlActivated">#FFFFFF</item>
<item name="colorControlHighlight">#FFFFFF</item>
</style>
Hope it will help you

Android normal button turns transparent

I have a RelativeLayout with a background set with android:background="#drawable/background".
In my RelativeLayout` I have a standard button but when I run the app in devices running 3.1 or higher the button are displayed transparent.
I have tried setting android:alpha to 1 with no luck.
I know I can make a custom background with selector and shapes but there has to be another way.
Anyone else had this problem?

You'll want to add something like this to your style.xml
Application theme
<style name="ApplicationStyle" parent="android:Theme">
<item name="android:buttonStyle">#style/MyButtons</item>
</style>
Button style
<style name="MyButtons" parent="#android:style/Widget.Button">
<item name="android:textSize">16sp</item>
<item name="android:background">#000000</item>
</style>
Make sure you're setting your theme correctly in the manifest also
<application
android:allowBackup="true"
android:icon="#drawable/app_icon"
android:label="#string/app_name"
android:theme="#style/Theme.ApplicationStyle" >

Simple Android app color

I have an app where I haven't explicitly defined any colors. The app looks different on my phone than it does on a few other phones around my office (the title bar at the top of the app on my phone is blue with white letters and on other phones it's gray with white letters). How do I make them all the same? Is it as simple as just explicitly setting the color in my app?

You need to apply one of available themes to your application. You can do it AndroidManifest.xml, just use android:theme attribute:
android:theme="#android:style/Theme.Holo" if you want dark theme or android:theme="#android:style/Theme.Holo.Light" if you want light theme.
If you use put this app in one of your <activity> tags, only corresponding activity will be styled, if you put it in <application> tag, style will be applied to the whole application.
Of course, you can define your own style in styles.xml:
<style name="AppTheme" parent="android:Theme.Light">
<item name="android:windowBackground">#drawable/bg_window</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style>
Here's the example of AndroidManifest.xml:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
>
<activity
android:name=".Activity1"
android:theme="#style/AppTheme2"
/>
<activity
android:name=".Activity2"
/>
In this example, AppTheme2 will be applied only to Activity1, while AppTheme will be applied to all other activities.

All the buttons, textviews and other UI elements not designed by you will change their aspect depending on the selected Theme. If you choose the default theme, all the GUI widgets will look different depending on the device manufacturer, the Android version, etc.
You can specify a concrete theme, such as Holo, with the problem that it won't work on Android versions prior to 3.0. You can keep the default theme for the old version, or otherwise you can use this website to generate all the Holo-style GUI elements yourself:

the title bar at the top of the app on my phone is blue with white
letters and on other phones it's gray with white letters
This is the problem with the customized frameworks of some OEMs. They override the default android styles. I assume that the device with a blue title bar is a Samsung device with TouchWiz on it, right?
I order to have a consistent title bar you'll have to declare your own theme:
<style name="AppTheme" parent="android:Theme.Light">
<item name="android:windowBackground">#drawable/title_bar</item>
<item name="android:windowTitleStyle">#style/WindowTitle</item>
</style>
<style name="WindowTitle">
<item name="android:singleLine">true</item>
<item name="android:textAppearance">#style/TextAppearance.WindowTitle</item>
<item name="android:shadowColor">#BB000000</item>
<item name="android:shadowRadius">2.75</item>
</style>
The original title_bar 9 patch.
This is the answer to your question. However in my opinion you should't use title bars, use the ActionBar instead. You can use ActionBarSherlock for backwards compatibility.

Is it possible to change android background black colour?

Is it possible to change the colour of background while switching between activities?
I mean the black colour what apear while one of activities disappear and before second appear. Thanks.

Just you need to head over to the activity_home.xml
At the starting lines of code add this background parameter to set the screen black
android:background="#ffffff"

you may change the theme that you are using as follows:
application android:icon="#drawable/icon" android:label="#string/app_name"
android:theme="#android:style/Theme.Light" >
Edit
as mentioned in the documentation:
<application android:theme="#style/CustomTheme">
and then tweak the theme that you like:
<style>
<color name="custom_theme_color">#b0b0ff</color>
<style name="CustomTheme" parent="android:Theme.Light">
<item name="android:windowBackground">#color/custom_theme_color</item>
<item name="android:colorBackground">#color/custom_theme_color</item>
</style>
