初始化

implementation 'com.github.warkiz.widget:indicatorseekbar:2.1.2'

使用

xml

<com.warkiz.widget.IndicatorSeekBar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:isb_max="100"
    app:isb_min="-1.0"
    app:isb_progress="25"
    app:isb_seek_smoothly="true"
    app:isb_ticks_count="5"
    app:isb_show_tick_marks_type="oval"
    app:isb_tick_marks_size="13dp"
    app:isb_tick_marks_drawable="@mipmap/ic_launcher"
    app:isb_show_tick_texts="true"
    app:isb_tick_texts_size="15sp"
    app:isb_tick_texts_color="@color/color_blue"
    app:isb_thumb_color="@color/color_green"
    app:isb_thumb_size="20dp"
    app:isb_show_indicator="rounded_rectangle"

    app:isb_track_background_size="2dp"
    app:isb_track_progress_color="@color/color_blue"
    app:isb_track_progress_size="4dp" />

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)
                .build();

指示器总是停留

将IndicatorSeekBar放进IndicatorStayLayout后可以使Indicator总是停留，在此之前，请确保你使用属性去显示indicator.

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" <!--显示指示器属性不能为none-->
        ....../>
    <!--your layout-->
</com.warkiz.widget.IndicatorStayLayout>

Java

IndicatorSeekBar seekbar = IndicatorSeekBar
                .with(getContext())
                .max(50)
                .min(10)
                .showIndicatorType(IndicatorType.RECTANGLE) //显示指示器属性不能为none
                ...
                .build();

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

自定义指示器文字

向IndicatorSeekBar设置一个带有占位符的格式字符串,${PROGRESS} 或者 ${TICK_TEXT},指示器的文字就会改变.

例如: 如果你想显示带百分号后缀的指示器进度文字: % ，代码如下：

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

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

如果你想显示带前缀 I am的指示器tick text文字 ，代码如下：

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

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

自定义每一节的track块颜色

seekbar上每一块track的颜色都能被设置：

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
    }
});

支持Selector类型的图片或颜色

你可以为滑块和tick标记设置StateListDrawable 或者 ColorStateList, 而且，tick下面的文字也支持ColorStateList,使用的格式如下:

滑块图片 selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--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>

滑块颜色 selectorr:

<?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>

tick标记图片 selector：

<?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 left 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>

tick标记颜色 selector：

<?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 left 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>

tick文字颜色 selector：

<?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 left 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>

监听器

seekBar.setOnSeekChangeListener(new OnSeekChangeListener() {
            @Override
            public void onSeeking(SeekParams p) {
                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) {
            }
        });
