SimpleRangeView

License Download Android Arsenal

SimpleRangeView is custom view component for Android, written in Kotlin, that provides for the selection of a range of discrete values designated by tick marks.

Gradle

dependencies {
	compile 'me.bendik.simplerangeview:simplerangeview:0.2.0'
}
Basic usage RangeView Builder

Attributes

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

Range Attributes

name format description default value
lineColor color Range bar color #F7F7F7
activeLineColor color Active range bar color #0C6CE1
fixedLineColor color Fixed range bar color #E3E3E3
lineThickness dimension Range bar thickness 4
activeLineThickness dimension Active range bar thickness 6
fixedLineThickness dimension Fixed range bar thickness 6
innerRangePadding dimension Range inner padding 16
innerRangePaddingLeft dimension Range inner left padding 16
innerRangePaddingRight dimension Range inner right padding 16
movable boolean It allows to move the entire active range false
showFixedLine boolean Show fixed range bar false
count integer Count of ticks 10
start integer Start of active range 0
end integer End of active range 9
minDistance integer Minimal active range length 1
maxDistance integer Maximal active range length 0 ~ count
startFixed integer Start of fixed range 0
endFixed integer End of fixed range 0

Tick Attributes

name format description default value
tickColor color Range bar tick color #C5C5C5
activeTickColor color Active tick color #FFFFFF
fixedTickColor color Fixed tick color #C5C5C5
tickRadius dimension Tick radius 1
activeTickRadius dimension Active tick radius 1
fixedTickRadius dimension Fixed tick radius 1
showTicks boolean Show ticks true
showActiveTicks boolean Show fixed ticks true
showFixedTicks boolean Show active ticks true

Label Attributes

name format description default value
labelColor color Label color #C5C5C5
activeLabelColor color Active label color #0C6CE1
fixedLabelColor color Fixed label color #0F7BFF
activeThumbLabelColor color Active thumb label color #C5C5C5
fixedThumbLabelColor color Fixed thumb label color #C5C5C5
labelFontSize dimension Label font size 12
labelMarginBottom dimension Label bottom margin 16
showLabels boolean Show labels true

Thumb Attributes

name format description default value
activeThumbColor color Active thumb color #0F7BFF
activeFocusThumbColor color Focused thumb color #0F7BFF
fixedThumbColor color Fixed thumb color #E3E3E3
activeFocusThumbAlpha float Focused thumb alpha 1.0
activeThumbRadius dimension Active thumb radius 10
activeThumbFocusRadius dimension Focused thumb radius 14
fixedThumbRadius dimension Fixed thumb radius 10

Examples

Layout XML

This is a SimpleRangeView with a lower and upper value, count of ticks and fixed range

<me.bendik.simplerangeview.SimpleRangeView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fixed_rangeview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:count="10"
    app:start="3"
    app:end="6"
    app:showFixedLine="true"
    app:startFixed="2"
    app:endFixed="7"
    />

This is a SimpleRangeView with movable active range and minimal length of active range

<me.bendik.simplerangeview.SimpleRangeView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fixed_rangeview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:count="10"
    app:start="3"
    app:end="6"
    app:movable="true"
    app:minDistance="2"
    />

Adding listeners

rangeView.setOnRangeLabelsListener(new SimpleRangeView.OnRangeLabelsListener() {
    @Nullable
    @Override
    public String getLabelTextForPosition(@NotNull SimpleRangeView rangeView, int pos, @NotNull SimpleRangeView.State state) {
        return String.valueOf("L" + (pos+1));
    }
});

rangeView.setOnTrackRangeListener(new SimpleRangeView.OnTrackRangeListener() {
    @Override
    public void onStartRangeChanged(@NotNull SimpleRangeView rangeView, int start) {
        editStart.setText(String.valueOf(start));
    }

    @Override
    public void onEndRangeChanged(@NotNull SimpleRangeView rangeView, int end) {
        editEnd.setText(String.valueOf(end));
    }
});

rangeView.setOnChangeRangeListener(new SimpleRangeView.OnChangeRangeListener() {
    @Override
    public void onRangeChanged(@NotNull SimpleRangeView rangeView, int start, int end) {
        editRange.setText(String.valueOf(start) + " - " + String.valueOf(end));
    }
});

Using Builder

final SimpleRangeView rangeView = new SimpleRangeView.Builder(this)
        .count(10)
        .start(2)
        .end(7)
        .startFixed(1)
        .endFixed(8)
        .showFixedLine(true)
        .movable(true)
        .onChangeRangeListener(this)
        .onTrackRangeListener(this)
        .onRangeLabelsListener(this)
        .build();
