@Override
public int getBackgroundColor() {
    return Color.TRANSPARENT;
}

@Override
public int calcColor(int numOfRect, double percentOfHeight) {
    return Color.argb(150, (int)(255 * (1d - percentOfHeight)), 0, (int)(255 * percentOfHeight));
}

}

TextAdapter overriding example :

public class WordTextAdapter implements Cosin.TextAdapter {

private String word;

public WordTextAdapter(String word) {
    this.word = word;

    if (word.isEmpty()) return ' ';
    return word.charAt(numOfRect % word.length());
}
