Height of statusbar?

For those, like me, who want to use it in your XML layouts:

<...
  android:layout_marginTop="@*android:dimen/status_bar_height"
  ... />

Don't be confused by that Android Studio (2.2 Preview 3 -- at the moment of writing) doesn't support this notion. The runtime does. I took it from the Google's source code.

Rect rectgle= new Rect();
Window window= getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rectgle);
int StatusBarHeight= rectgle.top;
int contentViewTop= 
    window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
int TitleBarHeight= contentViewTop - StatusBarHeight;

   Log.i("*** Jorgesys :: ", "StatusBar Height= " + StatusBarHeight + " , TitleBar Height = " + TitleBarHeight); 

Get the Height of the status bar on the onCreate() method of your Activity, use this method:

public int getStatusBarHeight() { 
      int result = 0;
      int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
      if (resourceId > 0) {
          result = getResources().getDimensionPixelSize(resourceId);
      } 
      return result;
}
