Two methods are used to obtain the status bar height f, and two methods are used to obtain the status barMethod 1. 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.

To adapt to the display with different resolutions, bind the width attribute of the first ememplate to systemparameters. primaryscreenwidth, which is actually implemented by converter (see source ). The width attribute of the datatemplate of itemscontrol on the second layer also wants to be bound to systemparameters. primaryscreenwidth, so a converter is also customized. It should be noted that if the two-layer ememplate declares a resource, the binding of the Second-layer datatemplat
