Answer 1

finally, I just have a sudden thought. why not try modify it by java code. It works! following is the sample code:

protected void initViews(Context context) {
    LayoutInflater.from(context).inflate(getLayoutResId(), this);
    ButterKnife.bind(this);

    // set style, just once
    seekBar.setProgress(0);
    seekBar.setMax(0);

    seekBar.setPadding(0, 0, 0, 0);

    // ...
}
