Parallax Everywhere#

Android Arsenal

Parallax everywhere (PEW) is a library with alternative android views using parallax effects.

Demo

You can try the demo app on google play.

https://play.google.com/store/apps/details?id=com.fmsirvent.ParallaxEverywhereSample

Views with effect?

Android view PEW view
ImageView PEWImageView
TextView PEWTextView

How it works?

  • Any parallax views (PEW*) needs to be inside a view with scroll events, ej: scrollView, listView, gridView....
  • Parallax effect on views will be related to its position on device screen.
  • Parallax effect in ImageView is calculated with left image in Scale mode centerCrop, centerInside or center. You can't make more parallax effect.
  • Parallax effect in no image views needs a size parallax parameter (read: Attributes)

Show me the code

Gradle dependencies:

compile 'com.fmsirvent:parallaxeverywhere:1.0.4'

Code in layout:

  <!-- add on top parent layout: xmlns:pew="http://schemas.android.com/apk/res-auto" -->


   <FrameLayout
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:layout_weight="1">

        <com.fmsirvent.ParallaxEverywhere.PEWImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:layout_margin="10dp"
            android:scaleType="centerCrop"
            android:src="@drawable/alicante_explanada" />

        <com.fmsirvent.ParallaxEverywhere.PEWTextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="10dp"
            android:gravity="bottom|center_horizontal"
            android:text="@string/alicante_explanada"
            android:textColor="@android:color/white"
            pew:block_parallax_x="true"
            pew:parallax_x="160dp"
            pew:parallax_y="160dp"
            pew:reverse="reverseY" />

    </FrameLayout>

Proguard:

-dontwarn com.fmsirvent.ParallaxEverywhere.**

Attributes

All PEW

  • reverse = ["none", "reverseX", "reverseY", "reverseBoth"] Change the direction of parallax effect. Default value "none".

  • block_parallax_x and block_parallax_y = "boolean" Blocks parallax effect. Default value false.

  • interpolation = ["linear", "accelerate_decelerate", "accelerate", "anticipate", "anticipate_overshoot", "bounce", "decelerate", "overshoot"] Animation interpolation. Default value "linear".

  • update_onDraw = = "boolean" Experimental attribute: update the parallax effect on draw event. Try if the parents don't has scroll. Now only works on +API:16 (Jelly bean). Default value false.

Only: no image PEW

  • parallax_x and parallax_y = "dimension" In non widgets images is necessary specify the size of parallax effect. The size will be split in half for each side. Default value 0.
