MaterialRangeBar

MaterialRangeBar is a fork of 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.

Examples

Layout XML

This is a rangebar with both a lower and upper value

<com.appyvet.rangebar.RangeBar
        xmlns:custom="http://schemas.android.com/apk/res-auto"
        android:id="@+id/rangebar"
        android:layout_width="match_parent"
        android:layout_height="72dp"
        custom:tickStart="5"
        custom:tickInterval="1"
        custom:tickEnd="10"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp"/>

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

<com.appyvet.rangebar.RangeBar
        xmlns:custom="http://schemas.android.com/apk/res-auto"
        android:id="@+id/rangebar"
        android:layout_width="match_parent"
        android:layout_height="72dp"
        custom:rangeBar="false"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp"/>

Adding a listener

//TODO add a full example here

  • 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 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;
            }
        });

TODO

  • Better instructions.
  • Properly implement Map of strings to each value
