Adding to your project

This library is available through jCenter.


compile 'com.stephentuso:welcome:1.4.1'

If you use proguard, add the following to your proguard rules

-keepclassmembers class * extends com.stephentuso.welcome.WelcomeActivity {

  public static java.lang.String welcomeKey();

Basic Usage

Extend WelcomeActivity

To create a welcome screen, add a class to your project that extends WelcomeActivity and add it to AndroidManifest:

<activity android:name=".MyWelcomeActivity"

The theme must be a child theme of WelcomeScreenTheme

Override the Activity's configuration() method. Use WelcomeConfiguration.Builder to set it up:

@Override protected WelcomeConfiguration configuration() {

  return new WelcomeConfiguration.Builder(this)

 .page(new TitlePage(R.drawable.logo,

 .page(new BasicPage(R.drawable.image,


"More text.")

 .page(new BasicPage(R.drawable.image,

"Lorem ipsum",

"dolor sit amet.")



You do not need to override onCreate or call setContentView.

Note: For now, defaultBackgroundColor() needs to be called before adding pages.

Show the welcome screen

Welcome screens are started with WelcomeHelper. onSaveInstanceState is needed to be sure only one instance of the welcome screen is started. Add the following to the Activity you want to show the welcome screen before (probably your launcher activity):

WelcomeHelper welcomeScreen;  @Override protected void onCreate(Bundle savedInstanceState) {

  welcomeScreen = new WelcomeHelper(this, MyWelcomeActivity.class);


  @Override protected void onSaveInstanceState(Bundle outState) {



If you have issues with the buttons/indicator being covered by the nav bar, use one of the .SolidNavigation welcome screen themes.

To force the welcome screen to be shown, for example, to let the user view it again when a button is pressed, create a WelcomeHelper as shown above and call .forceShow().

Skipping/Back button behavior

By default, the welcome screen can be skipped, and pressing the back button will navigate to the previous page or close (skip) the welcome screen if on the first page. This can be changed with Builder.canSkip(), backButtonSkips() (only applies if canSkip is true), and backButtonNavigatesPages(). If you disable skipping, the welcome screen will not be stored as completed when it closes.

If you want to require users to navigate through the welcome screen before using the app, call canSkip(false) and close your app if the welcome screen's result is RESULT_CANCELED.

See Results below for how to respond if a welcome screen is canceled.

Included pages

The classes listed below are subclasses of WelcomePage and can be used with the page method of WelcomeConfiguration.Builder


A page with an image and a title. A parallax effect can be applied to the image.


TitlePage(@DrawableRes int drawableResId, String title)


A page with an image, heading, and description. A parallax effect can be applied to the image.


BasicPage(@DrawableRes int drawableResId, String title, String description)


Similar to the basic page, but instead of an image you can supply a layout that will have a parallax effect applied to it. The speed at which the layout's children move is determined by their position in the layout, the first will move the slowest and the last will move the fastest.


ParallaxPage(@LayoutRes int layoutResId, String title, String description)


Applies a parallax effect in the same way the normal parallax page does, but the layout you provide fills the whole fragment, and there isn't a header or description.


FullscreenParallaxPage(@LayoutRes int layoutResId)

Custom pages

You can add your own fragments to the welcome screen with FragmentWelcomePage:

@Override protected WelcomeConfiguration configuration() {

  return new WelcomeConfiguration.Builder(this)


 .page(new FragmentWelcomePage() {


protected Fragment fragment() {

 return new ExampleFragment();




See animations below for adding animations to custom fragments.

Custom Done Button

If you want to use a button in a custom fragment instead of the default done button, call useCustomDoneButton(true) on the builder and new WelcomeFinisher(MyFragment.this).finish() in the button's OnClickListener.

Bottom Layouts

The layout shown beneath the pages can be changed with the bottomLayout Builder method, which uses the WelcomeConfiguration.BottomLayout enum. The possible values are explained below.


The default layout, can have skip/previous buttons, the current page indicator, and next/done buttons.


Same as STANDARD, but the done button is an ImageButton rather than a Button. Uses a check mark as the image by default (that can be changed with styles).


Has two buttons side by side at the bottom with the current page indicator above them. By default the text is "Log In" and "Sign Up", but can be changed with styles. In your WelcomeActivity subclass, override onButtonBarFirstPressed and onButtonBarSecondPressed to handle clicks. More documentation will be added later, see ButtonBarWelcomeActivity in the sample for an example.


Same as BUTTON_BAR, but with just one button (uses onButtonBarFirstPressed for clicks).


Just the current page indicator, no buttons.


No layout; no buttons, no indicator



The provided themes are listed below.

Transparent status/navigation on API 19+. Content does not flow under status bar:

  • WelcomeSceenTheme - The default theme. For use with dark backgrounds; the text, indicator, and buttons are light colored.
  • WelcomeScreenTheme.Light - For use with light backgrounds; the text, indicator, and buttons are dark colored.

Transparent status bar, solid navigation bar on API 19+. Content does not flow under status bar:

  • WelcomeScreenTheme.SolidNavigation
  • WelcomeScreenTheme.Light.SolidNavigation

Transparent status bar, solid navigation bar on API 19+. Content flows under status bar:

  • WelcomeScreenTheme.SolidNavigation.UnderStatusBar
  • WelcomeScreenTheme.Light.SolidNavigation.UnderStatusBar


Typefaces and a few other things (animations, button visibility) have to be set with WelcomeConfiguration.Builder, but everything else that is customizable can be changed with styles.

You can add styles as shown below. Optional items are in square brackets.

<style name="CustomWelcomeScreenTheme" parent="SEE THEMES ABOVE">

<!---- TEXT STYLES ---->

<!-- Color of button text and titles/headings (in built in fragments) 

  By default, this is also the color of the done/next button -->

  <!-- Add any properties that can be applied to a TextView --> </style> 

Welcome screen keys

If you want to use multiple welcome screens (in different parts of your app) or have updated one and want to show it again, you can assign keys (Make sure they are unique!) to welcome screens by adding the following to your welcome screen Activity.

public static String welcomeKey() {

  return "Your unique key"; 

Note: Only change this to a new value if you want everyone who has already used your app to see the welcome screen again! This key is used to determine whether or not to show the welcome screen.


You can listen for the result of a welcome screen in the Activity that started it by overriding onActivityResult:

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {

  super.onActivityResult(requestCode, resultCode, data);

 if (requestCode == WelcomeHelper.DEFAULT_WELCOME_SCREEN_REQUEST) {

// The key of the welcome screen is in the Intent

String welcomeKey = data.getStringExtra(WelcomeActivity.WELCOME_SCREEN_KEY);

 if (resultCode == RESULT_OK) {

 // Code here will run if the welcome screen was completed

 else {

 // Code here will run if the welcome screen was canceled

 // In most cases you'll want to call finish() here



One use for this is making sure users see the whole welcome screen before using your app - disable skipping and then close your main activity when the welcome screen is canceled.


Animations that play as pages are scrolled can be added to your custom fragments by implementing WelcomePage.OnChangeListener. As an example, a fade effect is shown below.

@Override public void onScrolled(int pageIndex, float offset, int offsetPixels) {

  if (Build.VERSION.SDK_INT >= 11 && imageView != null) {



To add parallax effects similar to the included parallax page, use WelcomeUtils.applyParallaxEffect() in onScrolled. For example:

@Override public void onScrolled(int pageIndex, float offset, int offsetPixels) {

  if (parallaxLayout != null)

WelcomeUtils.applyParallaxEffect(parallaxLayout, false, offsetPixels, 0.3f, 0.2f);
