ParallaxListView

This library is no longer maintained, please use ParallaxRecyclerView instead.

This library will provide you to have Parallax effect on every item of your ListView. Sample shows how to implement this features as async image loading with Picasso

Compatibility

This library works on 2.2+ probably earlier as well, but i didn't even bother to test because i believe at some point we have to stop supporting every version ;)

Usage

Get your ParallaxListView instance, and set its adapter as shown in sample. You need to provide a ParallaxImageView, which will handle parallax effect, on your listView's item.

In your adapter create a ViewHolder which extends ParallaxViewHolder. You need to use these specifications:

viewHolder.itemView = convertView; viewHolder.setBackgroundImage((ParallaxImageView) convertView.findViewById(R.id.parallaxImageView));

And this method needs to be called on getView method to notify ParallaxImageView that will be displayed once again, so it will re-center itselfs.

viewHolder.getBackgroundImage().reuse();

If you wish to change Parallax effects ratio, you can simple call setParallaxRatio on code, or you can set it by xml with parallax_ratio attribute.

Download

Add library dependency to your build.gradle file:

dependencies {

 compile 'com.yayandroid:ParallaxListView:1.1' 
}

References

This library has been built by our designer's insistence. She's seen JBParallaxCell library on IOS and want it to have in Android as well. Researches lead me to this repository but it wasn't quite affective as it is on IOS, so here ParallaxListView.

cwac-adapter

Android comes with a few "wrapper" classes, like CursorWrapper, that make it relatively easy for you to add just a bit of functionality to an existing object. The wrapper delegates all behaviors to the wrapped object; you just override the specific behaviors you need. This works well in cases where there are many possible underlying implementations, so you could not robustly accomplish these ends by subclassing.

Android lacks such a wrapper for ListAdapter, though. There is a WrappedListAdapter entry in the SDK, but it is an interface, not an implementation.

So, CWAC offers an AdapterWrapper to fill this void.

cwac-colormixer

Sometimes, you want your users to pick a color. A simple approach is to give the user a fixed roster of a handful of colors -- easy, but limited. A fancy approach is to use some form of color wheel, but these can be difficult to use on a touchscreen and perhaps impossible without a touchscreen.

ColorMixer is a widget that provides a simple set of SeekBars to let the user mix red, green, and blue to pick an arbitrary color. It is not very big, so it is easy to fit on a form, and it is still fairly finger-friendly.

It is also packaged as a dialog (ColorMixerDialog), a dialog-themed activity (ColorMixerActivity), and a preference (ColorPreference).

Color Pickers

cwac-layouts

This project has a handful of Android containers (ViewGroup implementations) designed to handle specific scenarios:

AspectLockedFrameLayout that resizes itself, and its children, to fit within a specific aspect ratio
MirroringFrameLayout and an associated Mirror that duplicates and scales the contents of the MirroringFrameLayout onto the Mirror

Layouts

BounceProgressBar

Android BounceProgressBar Widget.

Progress Indicators

AndroidKioskMode
