Gradle:

Step 1. Add the JitPack repository in your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Step 2. Add the dependency

implementation 'com.github.rtugeek:colorseekbar:1.7.7'

Usage

XML

<com.rtugeek.android.colorseekbar.ColorSeekBar
  android:id="@+id/colorSlider"
  android:layout_width="match_parent"
  app:colorSeeds="@array/material_colors"
  android:layout_height="wrap_content" />

JAVA

colorSeekBar.setMaxPosition(100);
colorSeekBar.setColorSeeds(R.array.material_colors); // material_colors is defalut included in res/color,just use it.
colorSeekBar.setColorBarPosition(10); //0 - maxValue
colorSeekBar.setAlphaBarPosition(10); //0 - 255
colorSeekBar.setPosition(10,10); // An easier way to set ColorBar and AlphaBar

colorSeekBar.setShowAlphaBar(true);
colorSeekBar.setBarHeight(5); //5dpi
colorSeekBar.setThumbHeight(30); //30dpi
colorSeekBar.setBarMargin(10); //set the margin between colorBar and alphaBar 10dpi

Listener

colorSeekBar.setOnColorChangeListener(new ColorSeekBar.OnColorChangeListener() {
        @Override
        public void onColorChangeListener(int colorBarPosition, int alphaBarPosition, int color) {
            textView.setTextColor(color);
            //colorSeekBar.getAlphaValue();
        }
});

Vertical Bar

<com.rtugeek.android.colorseekbar.ColorSeekBar
  android:id="@+id/colorSlider"
  android:layout_width="match_parent"
  app:colorSeeds="@array/material_colors"
  app:isVertical="true"
  android:layout_height="wrap_content" />

getColor() issue

Render flow:
1.Activity->onCreate();
2.Activity->onResume();
3.ColorSeekBar->onMeasure();
4.ColorSeekBar->onSizeChanged();
5.ColorSeekBar->init();
6.ColorSeekBar->onMeasure();
7.ColorSeekBar->onDraw();

getColor()/getColors()/getColorIndexPosition() do not work correct until onDraw() method invoked. So, If you want to get color or something else form ColorSeekBar on Activity.onCreate() function, just do:

mColorSeekBar.setOnInitDoneListener(new ColorSeekBar.OnInitDoneListener() {
    @Override` `
    public void done() {
        mColorSeekBar.getColorIndexPosition(mColor);
        //mColorSeekBar.getColors();
        //mColorSeekBar.getColor();
    }
});
