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.

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) {

            }

            @Override
            public void onTouchEnded(RangeBar rangeBar) {

            }

            @Override
            public void onTouchStarted(RangeBar rangeBar) {

            }
        });

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.
• Kotlin conversion

Demo (Outdated)

Get it from the Google Play Store

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:1.4.8'
}

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:1.4.8') {
            exclude module: 'support-compat'
    }
}
