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

  compile 'com.github.rtugeek:colorseekbar:1.7.3'

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.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 [BETA]

  <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();
        }
    });
