Java

 IndicatorSeekBar seekBar = IndicatorSeekBar
                .with(getContext())
                .max(110)
                .min(10)
                .progress(53)
                .tickCount(7)
                .showTickMarksType(TickMarkType.OVAL)
                .tickMarksColor(getResources().getColor(R.color.color_blue, null))
                .tickMarksSize(13)//dp
                .showTickTexts(true)
                .tickTextsColor(getResources().getColor(R.color.color_pink))
                .tickTextsSize(13)//sp
                .tickTextsTypeFace(Typeface.MONOSPACE)
                .showIndicatorType(IndicatorType.ROUNDED_RECTANGLE)
                .indicatorColor(getResources().getColor(R.color.color_blue))
                .indicatorTextColor(Color.parseColor("#ffffff"))
                .indicatorTextSize(13)//sp
                .thumbColor(getResources().getColor(R.color.colorAccent, null))
                .thumbSize(14)
                .trackProgressColor(getResources().getColor(R.color.colorAccent,null))
                .trackProgressSize(4)
                .trackBackgroundColor(getResources().getColor(R.color.color_gray))
                .trackBackgroundSize(2)
        .onlyThumbDraggable(false)
                .build();

Indicator stay always

Put IndicatorSeekBar into a IndicatorStayLayout can make the indicator stayed always. By the way, make sure you had called the attr to show the indicator before.

Xml

<com.warkiz.widget.IndicatorStayLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <!--your layout-->
    <com.warkiz.widget.IndicatorSeekBar
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:isb_show_indicator="rectangle" <!--show indicator can not be NONE-->
        ....../>
    <!--your layout-->
</com.warkiz.widget.IndicatorStayLayout>

Java

IndicatorSeekBar seekBar = IndicatorSeekBar
                .with(getContext())
                .max(50)
                .min(10)
                .showIndicatorType(IndicatorType.RECTANGLE) //show indicator can not be NONE
                ...
                .build();

new IndicatorStayLayout(getContext()).attachTo(seekBar);

Custom indicator’s View

You can custom the indicator View by below way:

If you want to replace the indicator’s View on top part, you can call:

 seekBar.getIndicator().setTopContentView(yourTopView);

or want to custom the indicator’s View you want , you can call:

seekBar.getIndicator().setContentView(yourView);

Custom indicator’s text

Set a format string with placeholder ${PROGRESS} or ${TICK_TEXT} to IndicatorSeekBar, the indicator’s text would change. For example: If you want to show the progress with suffix: % ，the code like：

seekBar.setIndicatorTextFormat("${PROGRESS} %")

Kotlin:
seekBar.setIndicatorTextFormat("\${PROGRESS} %")

or want to show the tick text with prefix: I am ，the code like：

seekBar.setIndicatorTextFormat("I am ${TICK_TEXT}")

Kotlin:
seekBar.setIndicatorTextFormat("I am \${TICK_TEXT}")

Custom section tracks color

The color of every block of seek bar can also be custom.

seekBar.customSectionTrackColor(new ColorCollector() {
    @Override
    public boolean collectSectionTrackColor(int[] colorIntArr) {
        //the length of colorIntArray equals section count
        colorIntArr[0] = getResources().getColor(R.color.color_blue, null);
        colorIntArr[1] = getResources().getColor(R.color.color_gray, null);
        colorIntArr[2] = Color.parseColor("#FF4081");
        ...
        return true; //True if apply color , otherwise no change
    }
});

Selector drawable&color were supported

    <!--this drawable is for thumb when pressing-->
    <item android:drawable="@mipmap/ic_launcher_round" android:state_pressed="true" />
    <!--for thumb in normal-->
    <item android:drawable="@mipmap/ic_launcher" />
</selector>

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--this color is for thumb which is at pressing status-->
    <item android:color="@color/colorAccent" android:state_pressed="true" />
    <!--for thumb which is at normal status-->
    <item android:color="@color/color_blue" />
</selector>

TickMarks selector drawable：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--this drawable is for tickMarks those are at start side of thumb-->
    <item android:drawable="@mipmap/ic_launcher_round" android:state_selected="true" />
    <!--for tickMarks in normal-->
    <item android:drawable="@mipmap/ic_launcher" />
</selector>

TickMarks selector color：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--this color is for marks those are at start side of thumb-->
    <item android:color="@color/colorAccent" android:state_selected="true" />
    <!--for marks those are at right side of thumb-->
    <item android:color="@color/color_gray" />
</selector>

TickTexts selector color：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--this color is for texts those are at start side of thumb-->
    <item android:color="@color/colorAccent" android:state_selected="true" />
    <!--for tick text which is stopped under thumb -->
    <item android:color="@color/color_blue" android:state_hovered="true" />
    <!--for texts those are at right side of thumb-->
    <item android:color="@color/color_gray" />
</selector>

Listener

seekBar.setOnSeekChangeListener(new OnSeekChangeListener() {
            @Override
            public void onSeeking(SeekParams seekParams) {
                Log.i(TAG, seekParams.seekBar);
                Log.i(TAG, seekParams.progress);
                Log.i(TAG, seekParams.progressFloat);
                Log.i(TAG, seekParams.fromUser);
                //when tick count > 0
                Log.i(TAG, seekParams.thumbPosition);
                Log.i(TAG, seekParams.tickText);
            }

            @Override
            public void onStartTrackingTouch(IndicatorSeekBar seekBar) {
            }

            @Override
            public void onStopTrackingTouch(IndicatorSeekBar seekBar) {
            }
        });
