### 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:



```groovy

compile 'com.fmsirvent:parallaxeverywhere:1.0.4'

```



Code in layout:



```xml

  



   



        



        



    



```



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.
