Try this,

public static void setText(TextView textView, String text) {
    Spannable spannable = new SpannableString(text);

    // For Foreground Highlight
    spannable.setSpan(new ForegroundColorSpan(fromColor(ColorCode)), highlight.start, highlight.end, 0);

    // For Background Highlight
    spannable.setSpan(new BackgroundColorSpan(fromColor(ColorCode)), highlight.start, highlight.end, 0);

    textView.setText(spannable);
}

Try this,

TextView TV = (TextView)findViewById(R.id.mytextview01);

Spannable wordtoSpan = new SpannableString("I know just how to whisper, And I know just how to cry,I know just where to find the answers");        

wordtoSpan.setSpan(new ForegroundColorSpan(Color.BLUE), 15, 30, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

TV.setText(wordtoSpan);
