Android: How to set status bar and navigation bar semi transparent

Question

In some applications I noticed that the status bar and navigational bar are transparent however, not completely. I do not know if this is a background color or something else. Would someone tell me how to implement this? Thank you.

You can use this two method:

getWindow().setStatusBarColor(Color.parseColor("#20111111"));
getWindow().setNavigationBarColor(Color.parseColor("#20111111"));
