Demo I Enable private boolean isSliderAnimation = false; in MainActivity.java to apply this background pager transformation animation with Image translation effect..

Demo II Enable private boolean isSliderAnimation = true; in MainActivity.java to apply this background pager transformation animation without Image translation effect..

How to use

STEP 1:

Download the code and open arrays.xml.

<?xml version="1.0" encoding="utf-8"?>
<array name="landing_bg">
    <item>@color/light_green</item>
    <item>@color/light_purple</item>
    <item>@color/light_orange</item>
    <item>@color/light_cyan</item>
</array>

<array name="icons">
    <item>@drawable/email</item>
    <item>@drawable/calendar</item>
    <item>@drawable/shopping</item>
    <item>@drawable/socialnetwork</item>
</array>

<string-array name="titles" >
    <item>@string/email</item>
    <item>@string/calender</item>
    <item>@string/shopping</item>
    <item>@string/social_network</item>
</string-array>

<string-array name="hints" >
    <item>@string/email_hint</item>
    <item>@string/calender_hint</item>
    <item>@string/shopping_hint</item>
    <item>@string/social_network_hint</item>
</string-array>

Here I have added 4 slides with images, titles and title hints. You can update your png's, text content in above arrays.xml as per your project need and requirement.

Note: The array count of images, titles and title hints should be of same count to avoid IndexBoundException.

STEP 2:

Drop all your images that are to be used for making AppIntro's into drawable folders. To get exact output for multiple resolution and sizes, add scaled images seperately for drawable-xxxhdpi, drawable-xxhdpi, drawable-xhdpi, drawable-hdpi, drawable-mdpi etc., and fix the height and width of ImageView in viewpager_item.xml

Customization

To customize pager attributes like indicator stroke size, stroke color, solid color, solid size, solid color, selected color and unselected color, please open vpi_defaults.xml and customize according to your wish.

Following are the attributes that I have used in my project demo, you can also customize your own.

<resources>
    <bool name="default_circle_indicator_centered">true</bool> 
    <color name="default_circle_indicator_fill_color">#FFFFFFFF</color>  <!--change fill color-->
    <color name="default_circle_indicator_page_color">#40FFFFFF</color>  <!--change indicator un selected fill color-->
    <integer name="default_circle_indicator_orientation">0</integer> 
    <dimen name="default_circle_indicator_radius">3dp</dimen> <!--change radius of the circle-->
    <bool name="default_circle_indicator_snap">false</bool> 
    <color name="default_circle_indicator_stroke_color">#40FFFFFF</color> <!--change stroke color-->
    <dimen name="default_circle_indicator_stroke_width">1dp</dimen> <!--change stroke width-->
</resources>

The app which inspired me to create this repos

  • Background color transformation animation used in Google Inbox intro screen.
  • Image translation animation used in Duolingo intro screen.
