How can I change the titlebar color in an Android app?

I tried:

this.setTitleColor(Color.BLUE); 

but it changes color of written text on it not title bar color.

getWindow() method of Context return the current view context, for get the title bar of an Activity, android.id.id.title

View title = getWindow().findViewById(android.R.id.title);
View titleBar = (View) title.getParent();
titleBar.setBackgroundColor(Color.RED);`
