MaterialScrollBar

DEPRECIATED

MaterialScrollBar has been moved to MaterialScrollbar2. MaterialScrollbar2 has been re-written in Kotlin and should be generally faster and easier to use. This repo will be moved over to that address in the coming months. See you there!

Apache 2.0 Version Android Arsenal

An Android library that brings the Material Design 5.1 scrollbar to pre-5.1 devices. Designed for Android's recyclerView.

Documentation

Note: All customisation methods (setAutoHide, setBarColor, etc) return the materialScrollBar, so they can be chained together if wanted. Alternatively, you can just operate on a variable.

How to use

The library comes in two flavours, drag and touch. Try both out to see which you prefer.

Option 1 - Drag

<com.turingtechnologies.materialscrollbar.DragScrollBar
    android:id="@+id/dragScrollBar"
    android:layout_width="wrap_content"
    app:msb_recyclerView="@id/recyclerView"
    app:msb_lightOnTouch="[[boolean]]"
    android:layout_height="match_parent" />

or

Option 2 - Touch

<com.turingtechnologies.materialscrollbar.TouchScrollBar
    android:id="@+id/touchScrollBar"
    android:layout_width="wrap_content"
    app:msb_recyclerView="@id/recyclerView"
    app:msb_lightOnTouch="[[boolean]]"
    android:layout_height="match_parent" />

Additonal optional attributes:

  • msb_handleColor - Color
  • msb_barColor - Color
  • msb_handleOffColor - Color
  • msb_textColor - Color
  • msb_barThickness - Integer
  • msb_rightToLeft - Boolean

Please note that for both of these configurations, both recyclerView and lightOnTouch* must have a valid value. The recyclerView attribute should point to the id of the recyclerView to which you want to link the scrollbar.

* lightOnTouch behaves like this: A value of true will cause the handle to be grey until pressed, when it will become the normal accent color (as set). A value of false will cause the handle to always have the accent color, even when not being pressed.


My recyclerView elements aren't all the same size! What do I do?

If you are in the situation of using headers of one size and elements of another, we've developed a solution speicifcally for you. Please follow the tutorial here.

If you are in some other situation where you're elements are differently sized, implement ICustomScroller in your adapter and complete the included methods.


Indicators

To add an indicator, simply add the following line of code:

scrollBar.setIndicator({{Indicator}}, {{addSpace}});

The indicator should be either AlphatbetIndicator, DateAndTimeIndicator, or CustomIndicator. See below for specific instructions per indicator.

{{addSpace}} is a boolean which indicates whether there should be space in between the indicator and the bar. True adds space, as in the latest version of the Google Launcher, while false adds no space, as in the Android 5.1 system scrollbars.

To use an indicator, you MUST make your recyclerView's adapter implement the relevant interface. If you do not, the library will throw a runtime error informing you of your mistake. See documentation for the relevant interface.


Specific Indicators

AlphabetIndicator

Required Interface: INameableAdapter

To implement an AlphabetIndicator, which displays one character usually corresponding to the first letter of each item, add the following to the end of your scroll bar instantiation, or add it as a seperate line.

...setIndicator(new AlphabetIndicator(this));

DateAndTimeIndicator

Required Interface: IDateableAdapter

To implement a DateAndTimeIndicator, which displays any combination of time, day of the month, month, and year, add the following to the end of your scroll bar instantiation, or add it as a seperate line.

...setIndicator(new DateAndTimeIndicator(this, {{includeYear}}, {{includeMonth}}, {{includeDay}}, {{includeTime}}));

All of the arguments are booleans (except for this first one obviously). The indicator will dynamically size, add punctuation, and localise for you. All you need to do is provide a Date object for each element in your adapter. You should almost always use miliseconds since the epoch unless you have a good reason not to. Otherwise, the library might crash.

CustomIndicator

Required Interface: ICustomAdapter

To implement a CustomIndicator, which displays any text you want, add the following to the end of your scroll bar instantiation, or add it as a seperate line.

...setIndicator(new CustomIndicator(this));
