Recycler Fast Scroll

Widget for RecyclerView fast scrolling, like Android's built-in fast scroll option for ListView.
Supports any vertically scrolling LayoutManager, as well as proper integration for AppBarLayout.

Planned features are listed at the issues page.
You can download the sample APK from the releases page.

Sample

Dependency

Add this to your module's build.gradle file:

repositories {
  //...  maven {
 url "https://jitpack.io" 
}
 
}

dependencies {
  //...  compile 'com.github.pluscubed:recycler-fast-scroll:{
latest-version
}
@aar' 
}

The library is versioned according to Semantic Versioning.

Basic Usage

Add the widget to your layout file, e.g.:

<FrameLayout
  android:layout_width="match_parent"
  android:layout_height="match_parent">

<android.support.v7.widget.RecyclerView

android:layout_width="match_parent"

android:layout_height="match_parent" />

<com.pluscubed.recyclerfastscroll.RecyclerFastScroller

android:layout_width="wrap_content"

android:layout_height="match_parent"

android:layout_gravity="end" />  </FrameLayout>

Attach the RecyclerFastScroller to your RecyclerView:
```
fastScroller.attachRecyclerView(recyclerView);
```
If the adapter hasn't been set when you attach the fast scroller, call attachAdapter() afterwords.

See the sample project for demos.

AppBarLayout support

Use attachAppBarLayout(coordinatorLayout, appBarLayout). See the sample project for the demo.

Customization

Method	Attribute	Description
`setBarColor(int color)`	`rfs_barColor`	Color of scrollbar. Defaults to `colorControlNormal` attribute. Alpha of ~22% is applied to the drawable to match stock `ListView` fast scroller.
`setHandleNormalColor(int color)`	`rfs_handleNormalColor`	Color of handle. Defaults to `colorControlNormal` attribute.
`setHandlePressedColor(int color)`	`rfs_handlePressedColor`	Color of pressed handle. Defaults to `colorAccent` attribute.
`setTouchTargetWidth(int width)`	`rfs_touchTargetWidth`	Width of the touch target. Defaults to 24dp (while the Android docs recommend at least 48dp, 24dp is more practical considering it will block touch in the right of the `RecyclerView`).
`setHideDelay(int milliseconds)`	`rfs_hideDelay`	Hide delay in milliseconds. Defaults to 1500ms.
`setHidingEnabled(boolean enabled)`	`rfs_hidingEnabled`	Whether scrollbar is hidden after delay. Defaults to true.
`setOnHandleTouchListener(OnTouchListener listener)`	--	Sets listener for handle touch events.

Corresponding getters are also available.

CPOrm

Content Provider ORM for android. This ORM uses an android sqlite database as a backing store, but interactes with it using content providers. You use it like a normal ORM, by creating java objects, and then do all of you interations through the objects. And you get the added benefits of using it like normal content providers, so integration with list views and other components are simple.
