MaterialRangeBar

MaterialRangeBar is a fork from https://github.com/edmodo/range-bar that adds some basic material styling, as well as start and end values, values as floats and some other things. It is aiming to mimic this:

http://www.google.com/design/spec/components/sliders.html

It is similar to an enhanced SeekBar widget, though it doesn't make use of the SeekBar. It provides for the selection of a range of values as well as for a single value. The selectable range values are discrete values designated by tick marks; the pin (handle) will snap to the nearest tick mark. This is my first library project, apologies for poor coding, etc etc.

Supported on API Level 12 and above for animations.

Developers can customize the following attributes (both via XML and programatically):

Change Log

1.4.2 - Added option for rounding status Bar progress using mrb_rangeBar_rounded. Also Implemented seekbar to select the nearest tick, when clicked. Also Fixed Rangebar issue that was causing right pin to move left of left pin when both had same value.
1.4.1 - Small Ui fixes
1.4 - Added mrb_ prefix to all attributes. Also added mrb_selectorBoundaryColor and mrb_selectorBoundarySize attribute.  
1.3 - Stopped pins appearing on initialisation when temporary. Margin correct even if pin radius = 0. PR to correct motion down
1.2 - NPE fixed for movePin
1.1 - Merged pull requests
1.0 - Merged pull requests to fix range bar issues and issues in scrollview, promoted to 1.0 release due to few other PRs.
0.1 - released onto Maven Central. Fixed color pickers in sample. Added ability to set pin color via XML and pin text color via XML or programatically
0.0.1 - 0.0.7 - Initial releases.

Examples

Layout XML

This is a rangebar with both a lower and upper value

<com.appyvet.materialrangebar.RangeBar
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp"
        app:mrb_pinMaxFont="10sp"
        app:mrb_rangeBarPaddingBottom="12dp"
        app:mrb_selectorBoundaryColor="@color/accent"
        app:mrb_selectorBoundarySize="2dp"
        app:mrb_pinTextColor="#ACD123"
        app:mrb_selectorSize="10dp"
        app:mrb_temporaryPins="true"
        app:mrb_tickEnd="10"
        app:mrb_tickInterval="1"
        app:mrb_tickStart="5"/>

This is a seekbar with only a single pin (note rangeBar=false)

<com.appyvet.materialrangebar.RangeBar
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/rangebar"
        android:layout_width="match_parent"
        android:layout_height="72dp"
        app:mrb_rangeBar="false"/>

Adding a rangebar listener

Add a listener - rangeBar.setOnRangeBarChangeListener which returns left and right index as well as value.

rangebar.setOnRangeBarChangeListener(new RangeBar.OnRangeBarChangeListener() {
            @Override
            public void onRangeChangeListener(RangeBar rangeBar, int leftPinIndex,
                                              int rightPinIndex, String leftPinValue, String rightPinValue) {
            }

        });

Adding a text formatter

Formats the text inside the pin.

Add a formater - IRangeBarFormatter which will return the value of the current text inside of the pin
Transform string s into any string you want and return the newly formated string.

rangebar.setFormatter(new IRangeBarFormatter() {
            @Override
            public String format(String s) {
            // Transform the String s here then return s
                return null;
            }
        });

Plan for Future

Better documentation.
Properly implement Map of strings to each value

How to Use

In your project build.gradle. Add the following lines

allprojects {
    repositories {
        jcenter()
    }
}

Note: Don't put the above lines inside the buildscript block.

In your app build.gradle. Add the following lines

dependencies {
    implementation 'com.appyvet:materialrangebar:1.4.2'
}

if you are already using android support library inside your project and run into multiple version issues related to android support library then modify the gradle path like this

dependencies {
    compile ('com.appyvet:materialrangebar:1.4.2') {
            exclude module: 'support-compat'
    }
}
