SimpleRangeView

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.

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();
