ViewPager 3D

This project aims to provide a reusable ViewPager widget for Android. It is based on the ViewPager class from Androids V4 compatibility package. Because of that android-support-v4.jar needs to be included in the build path.

Dependencies

• android-support-v4.jar
• Animations are handled by https://github.com/JakeWharton/NineOldAndroids. Add NineOldAndrois as a library project

Features

• 3D overscroll effect
• 3D swipe effect
• subtle fade out during swipe and over scroll

Usage

Layout

<!--
  The ViewPager3d replaces a standard android.support.v4.view.ViewPager widget.
-->
<de.inovex.android.widgets.ViewPager3D
    android:id="@+id/view_pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

You can control the 3D effect with XML attributes:

<de.inovex.android.widgets.ViewPager3D
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/view_pager"
    app:overscroll_rotation ="1.75"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

All attributes are optional.

• overscroll_rotation (float): Determines the amount of rotation during over scroll. Maximum rotation angle is 90 degrees divided by this value. Default is 2
• overscroll_translation (integer): determines the maximum amount of translation along the z-axis during the overscroll. Default is 150.
• swipe_rotation (float). Controls maximum rotation during swipe. Maximum rotation angle is 90 degrees divided by this value. Default is 3.
• swipe_translation (integer): Maximum z-translation during swipe. Default = 100.
• overscroll_animation_duration (integer): Duration of animation when user releases the over scroll. Default is 400 ms.
• animate_alpha (boolean): if true the alpha value of the children views is decreased as they scroll out of the screen. Default is false because of performance issues.
