In my application I've customized multiple color SeekBar .But unable to set value(0,20,40) like this .Here is My Desire out put .

Here is my Xml

 <com.amiyo.CustomSeekBar
        android:id="@+id/seekBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:max="100"
        android:progress="5"
        android:progressDrawable="@android:color/transparent"
        android:thumb="@drawable/slider_thumb"
        android:thumbOffset="6dp"
        android:layout_gravity="center"
        />

Java Class. Oncreate Method

     SeekBar = ((CustomSeekBar) findViewById(R.id.seekBar));

        progressItemList = new ArrayList<ProgressItem>();

        // blue span
        mProgressItem = new ProgressItem();
        mProgressItem.progressItemPercentage = (blueSpan / totalSpan) * 100;
        mProgressItem.color = R.color.blue;
        progressItemList.add(mProgressItem);

        // green span
        mProgressItem = new ProgressItem();
        mProgressItem.progressItemPercentage = ((greenSpan / totalSpan) * 100);
        mProgressItem.color = R.color.green;
        progressItemList.add(mProgressItem);

        mProgressItem = new ProgressItem();
        mProgressItem.progressItemPercentage = (yellowSpan / totalSpan) * 100;
        mProgressItem.color = R.color.yellow;
        progressItemList.add(mProgressItem);

        SeekBar.initData(progressItemList);
        SeekBar.invalidate();
    }
}

Here is CustomSeekBar Class

    public class CustomSeekBar extends SeekBar {

    private ArrayList<ProgressItem> mProgressItemsList;

    public CustomSeekBar(Context context) {
        super(context);
    }

    public CustomSeekBar(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomSeekBar(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public void initData(ArrayList<ProgressItem> progressItemsList) {
        this.mProgressItemsList = progressItemsList;
    }

    @Override
    protected synchronized void onMeasure(int widthMeasureSpec,
                                          int heightMeasureSpec) {
        // TODO Auto-generated method stub
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }

    protected void onDraw(Canvas canvas) {
        if (mProgressItemsList.size() > 0) {
            int progressBarWidth = getWidth();
            int progressBarHeight = getHeight();
            int thumboffset = getThumbOffset();
            int lastProgressX = 0;
            int progressItemWidth, progressItemRight;
            for (int i = 0; i < mProgressItemsList.size(); i++) {
                ProgressItem progressItem = mProgressItemsList.get(i);
                Paint progressPaint = new Paint();
                progressPaint.setColor(getResources().getColor(
                        progressItem.color));

                progressItemWidth = (int) (progressItem.progressItemPercentage
                        * progressBarWidth / 100);

                progressItemRight = lastProgressX + progressItemWidth;

                // for last item give right to progress item to the width
                if (i == mProgressItemsList.size() - 1
                        && progressItemRight != progressBarWidth) {
                    progressItemRight = progressBarWidth;
                }
                Rect progressRect = new Rect();
                progressRect.set(lastProgressX, thumboffset / 2,
                        progressItemRight, progressBarHeight - thumboffset / 2);
                canvas.drawRect(progressRect, progressPaint);
                lastProgressX = progressItemRight;
            }
            super.onDraw(canvas);
        }

    }

}

Here is Output . How to set value 0,20,40 ?
