SCViewPager

Jazz for android

A simple ViewPager extends that provide scroll based animation like Jazz Hands for iOS. Jazz Hands library provided by IFTTT : https://github.com/IFTTT/JazzHands

Install

With Gradle (JCenter):

compile "com.dev.sacot41:scviewpager:0.0.4"

Start

First, add SCViewPager to your project. Create an activity with the viewPage and the views you want to animate.

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
	xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
	android:layout_height="match_parent"
	tools:context=".MainActivity">

	<com.dev.sacot41.scviewpager.SCViewPager
        android:id="@+id/viewpager_main_activity"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
	</com.dev.sacot41.scviewpager.SCViewPager>

	<TextView
        android:id="@+id/textview_to_animate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/white"
        android:text="@string/textview_bonjour"/>

Retrieve view and add animation after you have set viewPager and his adapter.

Point size = SCViewAnimationUtil.getDisplaySize(this);

View view = findViewById(R.id.textview_to_animate);
SCViewAnimation viewAnimation = new SCViewAnimation(view);
viewAnimation.startToPosition((int)(size.x*1.5), null);
viewAnimation.addPageAnimation(new SCPositionAnimation(this, 0, -(int)(size.x*1.5), 0));
mViewPager.addAnimation(viewAnimation);

Disclaimer

This project is not yet implemented in a real app and it's hasn't the pretension to implement all feature provided by JazzHand on IOS; this projects is a pretext to me to better understand animation based on scrollview (viewpager) and publish my first library on Jcenter.

If you want a more complete library, heck Nightonke library, he add more animation and correct some bug : https://github.com/Nightonke/WoWoViewPager.
