Android gets the height of the status bar and title bar

1. Get the status bar height:

Decorview is the top-level view in the window. You can obtain the decorview from the window. Then, decorview has a getwindowvisibledisplayframe method to obtain the display area of the program, including the title bar, but not the status bar.
So we can calculate the height of the status bar.

01. rect frame = new rect ();
02. getwindow (). getdecorview (). getwindowvisibledisplayframe (FRAME );
03. Int statusbarheight = frame. Top;
Rect frame = new rect ();
Getwindow (). getdecorview (). getwindowvisibledisplayframe (FRAME );
Int statusbarheight = frame. Top;

2. Obtain the title bar height:

The view obtained by the getwindow (). findviewbyid (window. id_android_content) method is the part of the title bar that the program does not contain. Then you can know the height of the title bar.

01. Int contenttop = getwindow (). findviewbyid (window. id_android_content). gettop ();
02. // statusbarheight is the height of the status bar requested above
03. Int titlebarheight = contenttop-statusbarheight
Int contenttop = getwindow (). findviewbyid (window. id_android_content). gettop ();
// Statusbarheight is the height of the status bar requested above
Int titlebarheight = contenttop-statusbarheight
