Get the height of the window status bar and title bar

1. Get the status bar height:

Decorview is the topmost view in window, you can get to decorview from window, and Decorview has a getwindowvisibledisplayframe method to get to the area displayed by the program, including the title bar , but does not include the status bar.

So we can figure out the height of the status bar.

[Java]View Plaincopy < param name= "allowfullscreen" value= "false" >< param name= "wmode" value= "Transparent" >

1. Rect frame = new Rect ();
2. GetWindow (). Getdecorview (). Getwindowvisibledisplayframe (frame);
3. int statusbarheight = Frame.top;

2. Get the title bar height:

GetWindow (). Findviewbyid (Window.id_android_content) This method can get to the part of the view that does not include the title bar, and then you can know the height of the title bar.

[Java]View Plaincopy < param name= "allowfullscreen" value= "false" >< param name= "wmode" value= "Transparent" >

1. int contenttop = GetWindow (). Findviewbyid (window.id_android_content). GetTop ();
2. Statusbarheight is the height of the status bar that is asked above
3. int titlebarheight = Contenttop-statusbarheight; (Statusbarheight see above)

As to the above point, since the window view is drawn with a certain delay, it is not possible to use the above method directly from OnCreate ()->onresume () in the visible phase of the window when acquiring the height of the status bar. There are 3 ways to solve this problem:
1. The onclick () method can be placed under the onclicklistener of a button;
2. Of course you can also get in OnPause ()->ondestroy ()
3. Use a handler. The test code is as follows:
Inside the OnCreate () method, execute:
Mhandler.postdelayed (R, 200);

[Java]View Plaincopy

2. Runnable r = New Runnable () {
4. @Override
6. public Void Run () {
8. Rect frame = new Rect ();
10. GetWindow (). Getdecorview (). Getwindowvisibledisplayframe (frame);
12. int statusbarheight = frame.top;
14. LOG.D (TAG, "&&&&" + statusbarheight);
16. }
18. };

The last suggestion is to get this value only once, and then store it, similar to the high-width gain of the screen, and reduce the duplication of system resources by using too much.
